Dietary Fibre


Dietary Fibre And Constipation

Compared to third world countries, the typical diet in the Western world contains less dietary fibre. This leads to illness. Conditions that are relatively rare in countries where people eat a diet high in natural fibre are common here.

Such conditions include cancer and diverticular disease of the large bowel. Cancer of the bowel is one of the commonest cancers in Britain. Constipation resulting from a low dietary fibre intake is common and leads to straining when opening your bowels; this can cause further problems such as haemorrhoids (piles) that can bleed and are painful.

Dietary fibre is good for you

It is now well accepted that increased fibre in the diet represents a better way of preventing constipation than uncontrolled, often excessive, use of laxatives by people with a poor diet. The elderly, particularly, have a low fibre intake and as a result suffer from more constipation. Wholemeal bread, fruit and vegetable consumption is better than taking laxatives. Increasing the amount of fibre in the diet has other benefits as well. People with a high fibre intake have less risk of diseases affecting the large bowel such as piles, diverticular disease, and also less risk of cancer. These diseases can cause considerable pain and bleeding, resulting in money being spent on medicines. Cancer, of course, is fatal if not caught early. Increasing fibre also helps to reduce your cholesterol level and promotes a smoother absorption of dietary sugars. Fruit and vegetables as sources of fibre also provide plenty of vitamins. Fruit and vegetables contain a variety of natural chemicals that will help protect your heart.

What should I eat?

Eat at least 3 portions of fruit of vegetables daily. A portion might be one apple, a pear, a small banana, or a handful of grapes or cherries. Choose a variety of vegetables each day. Use more peas, beans and lentils; in many meals you can replace some of the meat with beans. This is much cheaper and very nutritious. Eat at least 4 thick slices of wholemeal bread each day and use wholemeal flower for baking.

Other tips include using tinned beans. They are a good way of getting fibre and are already cooked. Dried beans, like red kidney beans, are a very good and cheap way of getting fibre, but need to be soaked for at least 5 hours before thorough cooking. After soaking and cooking for 10 minutes you can put them into stews, casseroles or soups, or cool them and use in salads and cold dishes.

Potatoes contain a lot of fibre in the skin so try using them baked or boil with their jackets on. Brown rice contains much more fibre than white rice, sticks less and has a tastier flavour. Use wholemeal pasta. Breakfast cereals are also a good source of fibre. Try those whose ingredients are wholegrains and avoid sugar coated cereals.

Losing weight

Make sure that you have plenty of fluid with your meals to make the fibre nice and soft. Increasing the amount of fibre in your diet might, at first, cause an increase in abdominal bloating and wind. After a while, this becomes less of a problem. Foods high in fibre will fill you up more easily and this will probably help you to avoid eating excessive amounts of food. Increasing dietary fibre can be helpful if you are trying to lose weight.

Cheap, delicious and nutritious

You do not have to add bran to your food to increase fibre. The fibre rich foods mentioned above contain plenty of vitamins, are cheap and are delicious too!

Chocolate-Good or Bad?


Chocolate

Chocolate has a long history as a favoured food of many cultures, including Aztec and Mayan. Today, it is considered a luxury food that should be eaten sparingly, since it can contribute to migraines, and obesity. However, new research is debunking these common fallacies. Studies are now indicating that chocolate or cocoa in moderation is actually good for us, and may help prevent heart disease, cancer and other degenerative illnesses, but more evidence is needed.

Vitamins, minerals and nutrients
The nutritional content of chocolate varies according to its recipe. Generally, chocolate contains:

  • Protein - needed for cell maintenance and repair.
  • Fat - mainly saturated fats, up to 50 per cent.
  • Vitamin E which is a fat-soluble vitamin essential for the integrity of cell membranes.
  • Calcium, phosphorus and magnesium minerals that are essential for strong bones and teeth.
  • Iron - needed to form haemoglobin, the oxygen-carrying compound in blood.
  • Caffeine - a nervous system stimulant.
  • Copper assists iron metabolism, formation of melanin (in hair and skin), and in the functioning of the central nervous system.

    The link to migraines
    Migraines are debilitating headaches caused by spasms of the arteries leading to the brain. The underlying mechanisms remain unclear, but a number of triggers seem to be needed to start the migraine process. Certain foods, including chocolate, are commonly cited as triggers. However, for most sufferers, chocolate can't start the migraine chain reaction by itself. Numerous international trials have found that other factors, such as stress (as a result of tiredness, excitement or anger) and hormones, need to be present at the same time. Fasting and some foods may also play a role. More research is needed before chocolate can be completely exonerated, but the evidence so far seems promising for chocolate lovers.

    Acne and pimples
    A recent study has shown that most people, around 70 per cent, believe that certain foods can cause or exacerbate acne. Chocolate was indicated as one of the main culprits. However, there is no evidence to back up this long held belief. According to scientific research to date, there are no compounds, ingredients or naturally occurring chemicals in chocolate that can either trigger acne or make it worse.

    Obesity
    If a person regularly eats more food than their body needs, they will store the excess energy as body fat. Chocolate is energy dense, which means it contains comparatively high levels of kilojoules for its weight, approximately 2,200kJ per 100gm. Regularly eating energy dense foods is perhaps the fastest way to gain excess weight, but it would be wrong to say that regularly eating chocolate will lead to obesity. It is overeating in general that is the culprit, not specific foods. A person with a healthy diet can safely eat chocolate in moderation without fear of weight gain.

    A healthier type of saturated fat
    On average, chocolate contains around 50 per cent fat. Blood cholesterol levels are usually boosted by foods containing saturated fats, but the main type of saturated fat in chocolate is stearic acid. This type seems to have no effect on blood cholesterol levels at all, which means those who are trying to limit their saturated fat intake for the sake of their blood cholesterol could safely consume chocolate on the odd occasion.

    Heart disease and cancer
    Antioxidants, such as catechins, are substances found in some foods like tea, fruits and vegetables and are thought to protect the body against degenerative illnesses like heart disease and cancer. The antioxidant content of chocolate has been found to be significantly higher than tea. Chocolate, particularly dark chocolate, is a good source of catechins and may help prevent the oxidation of blood cholesterol and decrease the tendency for blood clotting. However, more evidence is needed on how these findings translate to heart health. If you want to boost your intake of catechins, while keeping your fat intake low, try drinking cocoa instead of eating chocolate, since it generally has a much lower fat content.

    Things to remember

  • Chocolate doesn't cause acne or automatically trigger migraine attacks.
  • The main type of saturated fat in chocolate is stearic acid, which doesn't increase blood cholesterol levels.
  • Chocolate and cocoa contain substances called catechins, which may help protect the body against degenerative illnesses like cancer.
  • Chocolate is a high fat food that must be consumed in moderation as part of an otherwise nutritious diet.
  • Cocoa provides the same amount of catechins as chocolate, but with less fat.
  • Sports Nutrition


    Sport Performance And Food

    It is common knowledge that poor diet is a decisive factor in many conditions and diseases, including obesity, certain types of cancer and heart disease. The link between good health and good nutrition has been well established, and interest in nutrition and its impact on sporting performance is now a science in itself. Whether you are a competing athlete, a weekend sports player or a dedicated daily exerciser, the cornerstone to improved performance is a well balanced diet.

    Daily requirements
    The basic training diet should:

  • Provide adequate energy and nutrients to meet the demands of training and exercise.
  • Include a wide variety of foods like wholegrain breads and cereals, vegetables (particularly leafy green varieties), fruit, lean meat and low fat dairy products.
  • Enable the athlete to achieve optimal body weight and body fat levels for performance.
  • Promote a quick and full recovery during exercise.
  • Provide adequate fluids to ensure maximum hydration.
  • Consider both the short and long term health of the individual.

    An athlete's diet should be similar to that which is recommended to the general population. Energy intake should divided into:

  • More than 55 per cent from carbohydrates
  • About 12 to 15 per cent from protein
  • Less than 30 per cent from fat.

    Athletes who exercise strenuously for more than 60 to 90 minutes daily may benefit from increasing the amount of energy they derive from carbohydrates to 65 to 70 per cent of energy intake. The World Health Organisation states that athletes can comfortably consume up to 35 per cent of energy from fat without compromising performance. Some sports nutritionists have recently suggested that extra fat in an athlete's diet may improve performance for endurance events - this is a new area of thought and is currently not widely recommended or practiced.

    Carbohydrates
    Foods rich in carbohydrate, particularly unrefined carbohydrates like wholegrain breads and cereals, should form the basis of the diet. More refined carbohydrate foods - such as white bread, jams and lollies - are useful to boost the total intake of carbohydrate. During digestion, all carbohydrates are broken down into a simple sugar, called glucose.
    Glucose is the body's primary energy source and is delivered to every cell via the blood. Excess glucose is converted into a substance called glycogen and stored in the liver and muscle tissue. Once glycogen stores are full, glucose is stored as fat, however, this storage process requires a lot of energy.

    Glycogen
    Glycogen is the most important energy source for the body during exercise.

    When you exercise, the glucose present in the blood is used as an energy source. The body converts the stored glycogen back into glucose in order to fuel the exercising muscle tissue and other body systems. Athletes can increase their stores of glycogen by regularly eating high carbohydrate foods. This is particularly important for athletes who exercise strenuously for more than 60 to 90 minutes daily.

    If carbohydrate in the diet is restricted, a person's ability to exercise is compromised due to poor glycogen storage. This can result in a loss of protein tissue (and muscle), as well as urinary loss of essential ions, such as potassium.

    Glycaemic index
    The glycaemic index (GI) ranks carbohydrate-rich foods based on their rate of digestion and absorption. Moderate to high GI foods can efficiently deliver carbohydrate to the body during exercise and recovery. This is why they are increasingly used by sportspeople. However, it is generally recommended that the bulk of the carbohydrate consumed in the overall diet should have a low glycaemic index.

    Eating should be tailored to maximise the performance of the particular sport in which the individual is involved. The type and timing of food eaten are often specific for different sports and different individuals.

    Pre-event meal
    A high carbohydrate meal three to four hours before exercise is thought to have a positive effect on performance. A small snack, one to two hours, before exercise may also benefit performance. Some people's blood glucose levels may react negatively to eating close to exercise - it varies between individuals.

    The pre-event meal should be easily digestible, high carbohydrate, low fat, low fibre and known not to cause gastrointestinal upset. Examples of suitable pre-competition snacks include fresh fruits and juices, muesli bars (without the chocolate coating), bread, toast, cereal with low fat or skim milk. Contrary to popular belief, consuming sugary foods or drinks just before a sporting event doesn't give your energy levels an immediate boost.

    Eating during exercise
    If exercise lasts longer than 60 minutes, it might be a good idea to eat some source of carbohydrate during exercise to top up blood glucose levels and delay fatigue. Low fat and low fibre food choices of a high glycaemic index, such as lollies (without chocolate) and sandwiches made with white bread, are ideal in these situations. Sports drinks and very diluted cordial or fruit juice offer the benefit of delivering both carbohydrate and fluid to the body.

    Eating after exercise
    To top up glycogen stores after exercise, the best foods to eat are carbohydrates with a moderate to high glycaemic index. This is best done in the first half hour or so after exercise. This should then be followed by foods high in carbohydrate, with a low glycaemic index. Exercise should be avoided during recovery.

    Protein
    Protein is an important part of a training diet. It plays a key role in post-exercise recovery and repair. Protein needs are generally met by following a high carbohydrate diet, because many foods - especially cereal-based foods - are a combination of carbohydrate and protein.

    The amount of protein recommended for sporting people is only slightly higher than that recommended for the general public. For example:

  • General public and active people - the daily recommended amount of protein is 0.75gmper kg of body weight (a 60kg person should eat around 45gm of protein daily).
  • Sports people involved in non-endurance events - who exercise daily for less than 60 minutes: daily protein intake should be between 0.75 to 1.0gm of protein per kg of body weight per day.
  • Sports people involved in endurance events and strength events - who exercise for longer periods (more than one hour) or who are involved in strength exercise, such as weight lifting, should consume about 1.24 to 1.7gm of protein per kg of body mass.

    Dietary surveys have found that most athletic groups comfortably reach and often exceed their protein requirements by consuming a high energy diet. Despite this, protein and amino acids (the building blocks of protein) are popular nutritional supplements.

    Amino acids and supplements
    Amino acids are important in many areas of the metabolism affected by exercise. This is why many people believe that additional protein, or even specific amino acid supplements, will provide additional benefits for athletes involved in intense training. This is not the case. Dietary supplements with protein are not likely to provide any benefit for athletes. Too much protein in the diet can be potentially dangerous to both short and long term health.
    Too much protein can:

  • Strain the kidneys and make them susceptible to kidney failure.
  • Compromise bone density.
  • Lead to weight gain if food choices are also high in fat.

    Vitamin supplements
    A well planned and nutritionally adequate diet should meet an athlete's entire vitamin and mineral needs. Taking vitamin or mineral supplements can only be of benefit if a person's diet is inadequate, or where a deficiency has been diagnosed, such as in the case of iron or calcium. There is no evidence to suggest that mega-doses of vitamins can improve sporting performance. The indiscriminate use of vitamins and mineral supplements is potentially dangerous and they should not be taken without the advice of a qualified health professional. Dietary imbalances should be rectified by analysing and altering the diet, rather than by using a supplement or pill.

    Water
    Heavy sweating depletes the body of water. Dehydration can impair athletic performance and, in extreme cases, can lead to collapse and even death. Drinking plenty of fluids before, during and after exercise is very important. The thirst mechanism should not be relied upon as a reliable indication to drink.

    Following exercise, you should drink 500ml of water for every 0.4 to 0.5kg of weight lost during exercise. Fluids are especially important in warm and humid conditions. Water is the preferred fluid in most situations. Sports drinks may be useful in ultra-endurance events (greater than 90 minutes) or when a quick recovery is necessary. If you prefer taking commercially prepared sports drinks, make sure that they are low in sodium - no more than about 30mmol (millimoles) per litre. Sodium can interfere with glucose getting into the cells and may exacerbate dehydration.

    Pregnant women, children, adolescents and the elderly should pay particular attention to their fluid intake.

    The use of salt tablets to combat muscle cramps is no longer advised, since it is lack of water - not lack of sodium - which affects the muscle tissue. Persistent muscle cramps might be due to zinc or magnesium deficiencies.

    Things to remember

  • Good nutrition can enhance sporting performance.
  • Carbohydrate should form the basis of the diet.
  • A diet high in protein isn't generally needed or recommended, since it can hinder performance, impair kidney function and compromise bone integrity.
  • Athletes can increase their stores of glycogen by regularly eating high carbohydrate foods.

  • Vitamins and Minerals


    Vitamins And Minerals

    Unlike protein, carbohydrates and fats, vitamins do not yield usable energy when broken down. They assist the enzymes that release energy from carbohydrates, proteins and fats, but they do not provide energy themselves. (thus, beware of claims for "energy vitamins" or for diets that replace foods with vitamin supplements)

    Vitamins and minerals are widely available from the natural foods we eat. So, before you reach for the vitamin jar, try eating your vitamins from natural foods.

    Cholesterol lowering foods

    'Functional' for your heart

    For years, a "healthy diet" has been largely defined by foods that should be avoided. We've learned to (try to) stay away from potato chips, cookies and virtually everything else that tastes good. Now, the focus may be about to shift toward foods you should work to include in your diet. When major food manufacturers introduce new, specially engineered product lines, their message may be: Eat our cereals, pastas, and even cookies and potato chips as part of your healthful diet.

    These new products, enhanced with natural ingredients, are being called "functional foods." According to the American Dietetic Association (ADA), functional foods may provide specific health benefits beyond basic nutrition when consumed as part of a varied diet. Many of the first functional foods to hit the shelves will tout the ability to lower cholesterol, a major contributing factor in cardiovascular disease, the leading cause of death in the United States and other industrialized countries.

    However, you don't need to wait until functional foods reach supermarket shelves to make your diet more heart-healthy. "The idea of functional foods came, in part, from understanding which components in natural foods help lower cholesterol, such as soluble fiber, soy protein and plant sterols," says Tu T. Nguyen, M.D., an endocrinologist at Mayo Clinic, Rochester, Minn.

    A careful review of what's already in your kitchen may reveal a ready cholesterol-fighting menu.

    Natural foods

    Natural foods fight cholesterol in a number of ways. Although dietary supplements are available for many of these natural substances, they are generally not as effective as the real thing.

    Consider increasing your intake of foods containing the following cholesterol-lowering components:

    Soluble fiber
    We've all heard the phrase, "An apple a day keeps the doctor away." But did you know that adage also holds true for lentils? Apples and lentils are both rich in soluble fiber, which regulates your body's production and elimination of cholesterol. Other good sources of soluble fiber include dried beans, peas, barley, citrus fruits, carrots and oats. Products containing lots of rolled oats and oat bran were the first to receive approval from the Food and Drug Administration (FDA) to boast on their labels that they may reduce the risk of heart disease when combined with a diet low in saturated fat and cholesterol. However, in order to reap the cholesterol-lowering benefits of oats, you must eat a sizable portion — the equivalent of about 3/4 cup of raw oatmeal each day.

    Soy
    Scientists first suspected a connection between soy and lower cholesterol levels after observing that people in Asian countries where diets contain much more soy than in the United States — have significantly lower levels of heart disease than Americans. Experts believe natural soy compounds called isoflavones act like human hormones that regulate cholesterol levels. A 1998 study concluded that regular consumption of soy isoflavones may reduce total cholesterol levels by up to 10 percent.

    A minimum of 25 grams of soy protein must be consumed daily in order to reap optimal cholesterol-lowering benefits. Good sources of soy protein include soy milk, tempeh, tofu, and textured soy protein, a main ingredient in many meat substitutes.

    Fish
    Researchers have found that, in general, the more fish people eat, the less coronary artery disease they have. Fish contain high concentrations of a unique type of fat, omega-3 polyunsaturated fatty acids (PUFAs). In addition to lowering blood fats (triglycerides), studies suggest that omega-3 PUFAs make the blood more slippery and less likely to clot.

    A unique study completed in 1997 provided compelling evidence that eating fish can reduce blood cholesterol levels. Researchers studied people in two African villages located 40 miles apart. People from both villages had very similar lifestyles, but their diets were quite different. While one group ate a fish-heavy diet, the other group ate a healthy vegetarian diet consisting largely of rice and maize. Researchers found that the villagers who ate lots of fish had lower cholesterol than the vegetarians. The American Heart Association recommends eating fish two or three times a week.

    Plant sterols
    Foods containing plentiful plant sterols naturally occurring compounds found in certain plants and vegetable oils also may improve cholesterol levels. "Plant sterols are known to specifically block cholesterol from being absorbed by the intestine," Dr. Nguyen says.

    However, very large portions of plant sterols extracted in powder form must be consumed in order to benefit. Functional foods may soon make heart-healthy consumption of plant sterols more feasible.

    Eating healthy foods to reduce your cholesterol is a great idea and a good way to ensure a healthy life. However, your diet might not be the only factor contributing to your high cholesterol. Some factors can only be remedied with cholesterol reducing drugs that your doctor can give you a prescription for. While eating a low-cholesterol diet is a fabulous idea, prescription drugs will help increase your chances of lowering your cholesterol.

    Healthy Diet-Basics

    Basics of a Healthy Diet

    What’s in a healthy diet? It’s hard to know these days, isn’t it? Regardless of the type of diet you eat, most all nutrition professionals agree on three basic concepts:

    Balance. Providing balance in your diet involves an intentional inclusion of different foods in proportion to each other based on the value that each food has to your total goal. For some, food choices might include a specific macronutrient balance. Most health organizations recommend a diet consisting of a balance from Carbohydrate at 55-65%, Protein at 10-15% and Fats at no higher than 30% of total calories. Other programs sometimes recommend that the nutrient balances be altered to a 40: 30: 30% or 75: 15: 10% Carbohydrate: Protein: Fat total calorie percent balance, respectively. Lastly, balance refers to choosing healthier foods more often than foods that are less healthy.

    Moderation. With obesity incidence growing at epidemic rates, one of the biggest concerns for Americans should be portion control. Moderation first involves learning how much food is enough and how much is too much. Many dieting programs are very successful simply because they are very good at helping clients learn to plan food portion sizes appropriately. Because the feeling of fullness in the stomach can take as long as twenty minutes to register to the brain, it is important to regulate how much food is ingested before waiting for a full-feeling. Moderation, therefore, also involves learning the distinct difference between hunger satisfaction and fullness.

    Variation. All healthy diets involve the inclusion of several food-types. The primary reason for this is health. Including a wide-variety of foods increases your likelihood of obtaining the required amounts of essential nutrients. It is well recognized that vitamin and mineral composition is food-specific. While some fruits are high in vitamin C, they are low in Calcium. Also, variation helps to avoid food-boredom: trying new foods can be interesting and exciting.

    Burning fat? How hard to exercise

    How Hard Do I Need to Exercise to Burn Fat?

    To answer this question we need to focus on two areas of the FIT principle (Frequency, Intensity, and Time of exercise). These two areas are intensity and time.

    Let's look at 2 sample workouts performed by the same individual exercising on a stairclimber.

    SESSION #1SESSION #2
    Percentage of MHR85%65%
    Exercise time30 minutes30 minutes
    Calories expended during exercise480300
    Percentage of calories from fat50%80%
    Fat calories utilized240240

    These numbers are used for the sole purpose of demonstrating how a higher intensity cardiovascular workout can achieve an equal or greater number of fat calories utilized as a lower intensity workout. Individuals caloric numbers will vary.

    So you can work out at a higher intensity and still burn an equal or greater number of fat calories as compared to a lower intensity workout. The following are added benefits of the higher intensity workout.

  • Larger number of total calories utilized
  • Metabolism remains elevated for a longer period of the time after exercise.
  • You gain a higher level of cardiovascular conditioning.

    Keep in mind that individuals who are ill or injured should start at a lower intensity level until they have regained their health.

    Should Burning Fat Calories Be My Goal?

    I think not. I believe that caloric expenditure should be our main goal in exercise when we are trying to lose fat weight. The reason is that 3,500 calories equals one pound of fat. Theoretically if we ate an extra 3,500 calories in a week, we would gain a pound. The same applies to eating 3,500 fewer calories than our body needs in a week - we would lose a pound. Instead of eating 3,500 fewer calories and depriving our bodies of the fiber and nutrients that we need, let's eat nutritionally dense food, make healthy food choices, and expend those calories in the form of exercise. Whether the majority of calories expended are from fat or glycogen, ultimately calories are calories when it comes to exercise.

    While keeping in mind that you don't want to exercise at such a high level that you can only last a few minutes, remember that the longer you exercise the more calories you expend, and the higher your intensity, the more calories you expend.

    If you are in good physical condition and you're trying to lose or maintain weight, and you feel like exercising at a higher heart rate, go ahead.

    Exercise Myths

    Fitness Tips - 10 Exercise Myths

    Although some old fitness fictions, such as "no pain, no gain" and "spot reducing" are fading fast, plenty of popular exercise misconceptions still exist. Here are some of the most common myths as well as the not-so-common facts based on current exercise research.

    1. You Will Burn More Fat If You Exercise Longer at a Lower Intensity. The most important focus in exercise and fat weight control is not the percentage of exercise energy coming from fat but the total energy cost, or how many calories are burned during the activity. The faster you walk, step or run, for example, the more calories you use per minute. However, high-intensity exercise is difficult to sustain if you are just beginning or returning to exercise, so you may not exercise very long at this level. It is safer, and more practical, to start out at a lower intensity and work your way up gradually.

    2. If You’re Not Going to Work Out Hard and Often, Exercise Is a Waste of Time. This kind of thinking keeps a lot of people from maintaining or even starting an exercise program. Research continues to show that any exercise is better than none. For example, regular walking or gardening for as little as an hour a week has been shown to reduce the risk of heart disease.

    3. Yoga Is a Completely Gentle and Safe Exercise. Yoga is an excellent form of exercise, but some styles are quite rigorous and demanding both physically and mentally. As with any form of exercise, qualified, careful instruction is necessary for a safe, effective workout.

    4. If You Exercise Long and Hard Enough, You Will Always Get the Results You Want. In reality, genetics plays an important role in how people respond to exercise. Studies have shown a wide variation in how different exercisers respond to the same training program. Your development of strength, speed and endurance may be very different from that of other people you know.

    5. Exercise Is One Sure Way to Lose All the Weight You Desire. As with all responses to exercise, weight gain or loss is impacted by many factors, including dietary intake and genetics. All individuals will not lose the same amount of weight on the same exercise program. It is possible to be active and overweight. However, although exercise alone cannot guarantee your ideal weight, regular physical activity is one of the most important factors for successful long-term weight management.

    6. If You Want to Lose Weight, Stay Away From Strength Training Because You Will Bulk Up. Most exercise experts believe that cardiovascular exercise and strength training are both valuable for maintaining a healthy weight. Strength training helps maintain muscle mass and decrease body fat percentage.

    7. Water Fitness Programs Are Primarily for Older People or Exercisers With Injuries. Recent research has shown that water fitness programs can be highly challenging and effective for both improving fitness and losing weight. Even top athletes integrate water fitness workouts into their training programs.

    8. The Health and Fitness Benefits of Mind-Body Exercise Like Tai Chi and Yoga Are Questionable. In fact, research showing the benefits of these exercises continues to grow. Tai chi, for example, has been shown to help treat low-back pain and fibromyalgia. Improved flexibility, balance, coordination, posture, strength and stress management are just some of the potential results of mind-body exercise.

    9. Overweight People Are Unlikely to Benefit Much From Exercise. Studies show that obese people who participate in regular exercise programs have a lower risk of all-cause mortality than sedentary individuals, regardless of weight. Both men and women of all sizes and fitness levels can improve their health with modest increases in activity.

    10. Home Workouts Are Fine, But Going to a Gym Is the Best Way to Get Fit. Research has shown that some people find it easier to stick to a home-based fitness program. In spite of all the hype on trendy exercise programs and facilities, the "best" program for you is the one you will participate in consistently.

    About Exercise

    About Exercise

    Working out should be a challenge, but it definitely should not be painful. If you find yourself running straight for the ice packs and aspirin after working out, you are probably doing something wrong. Before you convince yourself you have a wonderful excuse to quit, try evaluating your exercise program.

    First, determine if you are exercising at the proper level. A beginner should not try to bench press 300 lbs or run the treadmill at the highest level. Believe it or not, starting off slowly will actually make you stronger faster, as you will avoid injuring your muscles. Also, pain is an excellent deterrent. You should feel invigorated and even a little sore, but ever like a mouse who has hit the wrong feeder bar. If you are working out at a gym, ask a trainer to help you develop a proper exercise program. If you are exercising on your own, there is a myriad of books and resources from which to learn.

    Two important points people tend to minimize are stretching and warming up. These are a must. The stretching before you workout should be light, as your muscles are cold. Never bounce or be jerky. This increases the likelihood of tearing your muscles. Warm up for about 10 minutes then stretch lightly. After working out, you can stretch more thoroughly. It is very important to stretch the muscles you have just worked in order get the most out of the exercise. Stretching the muscles lengthens them and allows them to heal stronger and be more limber. Again, never bounce or jerk while stretching.

    Proper form is more than important, it is a must. If you are not executing the exercise properly, you might as well not be doing it at all. Improper form leads to injuries and an inefficient use of the muscle and your time. Do not tweak yourself in order to do more sets or to keep up with an aerobics instructor. It is always quality and not quantity that will get you results. Besides, it can be quite embarrassing to be spastically moving around or straining in an unnatural position.

    Further, be sure that you are giving your body ample rest time between workouts. One should not exercise the same muscles in the same manner every day. Exercising tears down the muscles. It is the healing of the muscles that makes them grow and become stronger. Try working your upper body one day and your lower body the next. Or, if you are a runner, alternate your long distance runs with weight training or short distance runs.

    Finally, it is always important to use the proper equipment. Even if you are working out at home, it is imperative that you have the proper equipment. If you are doing an aerobic workout video, it may be as simple as the right pair of shoes. If you are dead lifting 500 pounds, you will also need gloves and a back support. Do not skimp on the equipment. It not only can aid in the prevention of injuries, but also help you keep good form.

    If after trying all of these, you are still experiencing pain, be sure to check with your doctor. You may be doing an exercise that is not right for your body. Before you throw away your workout sweats and limp to your easy chair, be sure you are exercising correctly with the correct form and equipment. There are so many things that one can do to exercise. Don't give up.

    Benefits of Exercise

    What Are the Specific Benefits of Exercise?

    Longevity and Aging

    Exercise, even after age 50, can add healthy and active years to one's life. Studies continue to show that it is never too late to start exercising and that even small improvements in physical fitness can significantly lower the risk of death. Simply walking regularly can prolong life in the elderly. Moderately fit people, even if they smoke or have high blood pressure, have a lower mortality rate than the least fit. Resistance training is important for the elderly, because it is the only form of exercise that can slow and even reverse the decline in muscle mass, bone density, and strength. Adding workouts that focus on speed and agility may be even more protective for older people. Flexibility exercises help reduce the stiffness and loss of balance that accompanies aging.

    Cardiovascular Health (Heart Disease and Stroke)

    General Guidelines. Inactivity is one of the four major risk factors for heart disease, on par with smoking, unhealthy cholesterol, and even high blood pressure. Like all muscles, the heart becomes stronger and larger as a result of exercise so it can pump more blood through the body with every beat. Exercise does not increase the maximum heart rate, but a fit heart can pump more blood at this maximum level and can sustain it longer with less strain. The resting heart rate of those who exercise is also slower, because less effort is needed to pump blood. For preventing heart disease frequency of exercises may be more important than duration. Exercise even helps reverse some of the effects of smoking. Children should be especially encouraged to exercise every day to prevent heart disease later in life.

    Effect on Coronary Artery Disease and Cholesterol Levels. People who maintain an active lifestyle have a 45% lower risk of developing coronary heart disease than do sedentary people. A recent study reported that moderate dietary changes improve cholesterol levels and so lower the risk for coronary artery disease only when an aerobic exercise program is also followed. Regular aerobic exercises -- brisk walking, jogging, swimming, biking, aerobic dance, and racquet sports -- are the best forms of exercise for lowering LDL and raising HDL cholesterol levels. It may take up to a year of sustained exercise for HDL levels to show significant improvement. Burning at least 250 calories a day (the equivalent of about 45 minutes of brisk walking or 25 minutes of jogging) seems to confer the greatest protection against coronary artery disease. Even moderate exercise, however, reduces the risk of heart attack, but in terms of raising HDL levels, more is better. Resistance (weight) training offers a complementary benefit by reducing LDL levels. Triglycerides, which rise after a high-fat meal, can be lowered either with a single, prolonged (about 90 minutes) aerobic session or by several shorter sessions during the day. One study indicates, however, that short-bursts of exercise actually increase LDL oxidation -- the process that makes LDL dangerous to the heart -- so individuals should always aim for a consistency in their exercise program. Before engaging in any strenuous exercise, it is advisable to consult a physician.

    High Blood Pressure. Studies indicate that regular exercise helps keep arteries elastic, even in older people, which in turn keeps blood flowing and blood pressure low. Sedentary people have a 35% greater risk of developing hypertension than athletes do. No person with high blood pressure should start an exercise program without consulting a physician. Studies have shown that high-intensity exercise may not lower blood pressure as effectively as moderate intensity exercise. In one study, for example, moderate exercise (jogging two miles a day) controlled hypertension so well that more than half the patients who had been taking drugs for high blood pressure were able to discontinue their medication. Studies have indicated that T'ai Chi, an ancient Chinese exercise involving slow, relaxing movements may lower blood pressure almost as well as moderate-intensity aerobic exercises. Before exercising, people with hypertension should avoid caffeinated beverages, which increase heart rate, the workload of the heart, and blood pressure during physical activity.

    Stroke. The benefits of exercise on stroke are uncertain. According to one analysis, a group of 11,000 men, men who burned between 2,000 and 3,000 calories a week (about an hour of brisk walking five days a week) cut their risk of stroke in half. Groups who burned between 1,000 and 2,000 calories or more than 3,000 calories per week also gained some protection against stroke but to a lesser degree. In the same study, exercise that involved recreation was more protective than exercise routines consisting simply of walking or climbing.

    Heart Failure. Traditionally, heart failure patients have been discouraged from exercising. Now, exercise is proving to be helpful for many of these patients and, when performed under medical supervision, does not pose a risk for a heart attack. In one study, patients between the ages of 61 and 91 increased their oxygen consumption by 20% after six months by engaging in supervised treadmill and stationary bicycle exercises. Performing daily hand grip exercises may improve blood flow through the arteries of patients with heart failure.

    Diabetes

    Diabetes, particularly type 2, is reaching epidemic proportions throughout the world as more and more cultures adopt Western dietary habits. Aerobic exercise is proving to have significant and particular benefits for people with both type 1 and type 2 diabetes; it increases sensitivity to insulin, lowers blood pressure, improves cholesterol levels, and decreases body fat. Regular exercise, even of moderate intensity, improves insulin sensitivity. In fact, studies of older people who engage in regular, moderate, aerobic exercise (e.g., brisk walking, biking) lower their risk for diabetes even if they don't lose weight. Anyone on insulin or who has complications from diabetes must take special precautions before embarking on a workout program (see, What Are the Hazards of Exercise?, below).

    Effects on Bones and Joints

    Osteoarthritis. Exercise helps to reduce pain and stiffness, and increases flexibility, muscle strength, endurance, and well being. Exercising also helps people reduce their weight and maintain weight loss. Osteoarthritis patients should avoid high-impact sports such as jogging, tennis, and racquetball. The three types of exercise that are best for people with arthritis are range of motion, strengthening (or resistance), and aerobic exercises. Strengthening exercises include isometric exercises (pushing or pulling against static resistance) and stretching exercises to build strength and flexibility without unduly stressing the joints. These exercises may be particularly important if leg muscle weakness turns out to be a cause of osteoarthritis, as some research suggests. Low-impact aerobics also help stabilize and support the joints and may even reduce inflammation in some joints. Cycling and walking are beneficial, and swimming or exercising in water is highly recommended for people with arthritis.
    One study compared a group of patients who embarked on an aerobic and resistance exercise program with a group that received patient education; the exercising group developed less disability and pain and showed a better ability to perform physical tasks. Patients should strive for short but frequent exercise sessions guided by physical therapists or certified instructors.

    Osteoporosis. Exercise is very important for slowing the progression of osteoporosis. Women should begin exercising before adolescence, since bone mass increases during puberty and reaches its peak between ages 20 and 30. Weight bearing exercise, which applies tension to muscle and bone, encourages the body to compensate for the added stress by increasing bone density by as much as 2% to 8% a year. High-impact weight-bearing exercises, such as step aerobics, are very protective for premenopausal women. These exercises, however, increase the risk for osteoporotic fractures in elderly patients, who would benefit most from regular, brisk, long walks. Even moderate exercise (as little as an hour a week) helps reduce the risk for fracture, but everyone who is in good health should aim for more. Careful weight training is beneficial as well for older women. Low-impact exercises that improve balance and strength, particularly yoga and T'ai Chi, have been found to decrease the risk of falling; in one study, T'ai Chi reduced the risk by almost half.

    Back Problems. One of the most common complaints of modern men and women, lower-back pain, afflicts up to 80% of all Americans. Sedentary living, obesity, poor posture, badly designed furniture, and stress all contribute to back pain. An appropriate exercise program focusing on flexibility and strengthening the muscles in the abdomen may help prevent back problems. Yoga stretching is beneficial and can be incorporated into the warm-up and cool-down periods. The best exercises for athletes with bad backs include swimming, walking, and cross-country skiing. High-impact sports, including aerobic dance and downhill skiing, should be avoided. Exercises that strengthen the abdominal muscles such as partial sit-ups, which maintain the back's normal curve and help support the body's weight, can alleviate stress on the lower back. However, the classic full sit-up (raising your head and shoulders off the floor up to your knees) may aggravate back pain and should be avoided by anyone at risk for lower back problems.

    Lung Disease

    Although exercise does not improve lung function (except for intense, regular aerobic exercise), training helps some patients with chronic lung disease by strengthening their limb muscles, thus improving endurance and reducing breathlessness.

    Cancer

    A number of studies have indicated that regular, even moderate, exercise reduces the risk of colon cancer. Strenuous activity, in fact, adds only slight or no additional benefit. Moderate exercise may also help reduce the risk for prostate cancer and possibly for breast cancer. A recent study of 100,000 nurses, however, suggested that the benefits of exercise on breast health may be greater or lesser at different times in a woman's life, depending on her menstrual status and estrogen levels. For example, the study found no added protection against from exercise in young adulthood (when the disease is uncommon in any case).

    Effects on Colds and Flu

    Although offering no evidence of improved immunity from exercise, one study reported that people who exercised as little as once a week in employee fitness programs averaged nearly five fewer sick days annually than those who did not participate in such programs. The immediate effect of exercise on the immune system is uncertain. High-intensity or endurance exercises might actually suppress the immune system while they are performed. Some highly trained athletes, for instance, report being susceptible to colds after strenuous events. A recent study suggested that in people who already have colds, exercise has no effect on the illness -- severity or duration of the infection. People should avoid strenuous physical activity when they have high fevers or widespread viral illnesses, however.

    Central Nervous System Diseases

    People with multiple sclerosis, Parkinson's disease, and Alzheimer's disease should be encouraged to exercise. Specialized exercise programs that improve mobility are particularly valuable for Parkinson's patients. Patients with neurological disorders who exercise experience less spasticity as well as reduction in -- and even reversal of -- muscle atrophy. In addition, the psychological benefits of exercise are extremely important in managing these disorders. Exercise machines, aquatic exercises, and walking are particularly useful.

    Pregnancy

    Healthy women with normal pregnancies should exercise at least three times a week, being careful to warm up, cool down, and drink plenty of liquids. Many prenatal calisthenics programs are available. Experts advise, in general, that when exercising, the expectant mother's pulse rate should not exceed 70% to 75% of the maximum heart rate or more than 150 beats per minute. Fit women who have exercised regularly before pregnancy, however, may work out more intensively as long as no discomfort occurs.
    According to a new study, vigorous exercise may improve the chances for a timely delivery. Overly strenuous exercise during pregnancy is not advocated, however, for women who did not exercise intensely before becoming pregnant. And all pregnant women should avoid high-impact, jerky, and jarring exercises, such as aerobic dancing, which can weaken the pelvic floor muscles that support the uterus. During exercise, women should monitor their temperature to avoid overheating -- a side effect that can damage the fetus. (No pregnant women should use hot tubs or steam baths, which can cause fetal damage and miscarriage.)
    Swimming may be the best option for most pregnant women. It involves no impact, overheating is unlikely, and swimming face down promotes optimum blood flow to the uterus. Walking is also highly beneficial. To strengthen pelvic muscles, women should perform Kegel exercises at least 6 times a day, which involve contracting the muscles around the vagina and urethra for 3 seconds 12 to 15 times in a row.

    Gastrointestinal Problems

    Older people who exercise moderately may have a lower risk for severe gastrointestinal bleeding. Experts suggest that moderate exercise might even reduce the risk for some intestinal disorders, including ulcers, irritable bowel syndrome, indigestion, and diverticulosis.

    Leg Cramps

    Exercise can even improve pain from clogged arteries in the legs, a condition called intermittent claudication. The best approach in such cases is to walk until pain develops; then rest until pain resolves before resuming walking. In six-month studies, people had tripled the amount of time they could walk before the onset of pain.

    Weight Loss

    Exercise burns calories and can help individuals fight obesity. If caloric intake remains constant, regular workouts lead to weight loss. Be forewarned, however, that the pounds won't melt off magically. It takes 35 miles of walking or jogging to consume the calories in one pound of fat. Effective weight loss means a long-term commitment to a regular program of vigorous exercise. One recent study indicated that for obese patients, a few daily sessions for as short as 10 minutes each was effective in helping the patients adhere to an exercise program. Abdominal crunches may help replace abdominal fat with muscle. To perform this exercise, the individual lies on the back with the head and shoulders raised; he or she contracts the stomach muscles, curling the torso slightly forward. Abdominal fat is a particular danger to the heart, although it is unknown whether doing crunches will specifically protect against heart disease. Swimming is less effective than walking or cycling in reducing body fat, but overall regular aerobic exercise is a good way to shed pounds. Contrary to popular belief, exercise does not increase appetite in people who want to lose weight; oddly enough, however, exercise improves appetite in people who are already lean.
    People should be warned that without dieting, weight loss may be minimal with exercise alone, because dense muscle mass replaces fat as the body gets more fit. Nonetheless, a fit body will look more toned and be healthier.

    Psychological and Emotional Benefits

    Aerobic exercise is linked with improved mental vigor, including reaction time, acuity, and math skills. Exercising may even enhance creativity and imagination. According to one study, older people who are physically fit respond to mental challenges just as quickly as unfit young adults. (Stretching and weight training appear to have no such effects.) Both aerobic and nonaerobic workouts have been shown to reduce depression. According to one study, exercise was as effective for improving mood in people with clinical depression as some common forms of psychotherapy. Either brief periods of intense training or prolonged aerobic workouts can raise levels of important chemicals in the brain, such as endorphins, adrenaline, serotonin, and dopamine, that produce feelings of pleasure, causing the so-called runner's high. One study found that teenagers who were active in sports have a much better sense of well being than their sedentary peers; the more vigorously they exercised, the better was their emotional health. In one study, regular brisk walking cut in half the incidence of sleep disturbances in people who suffer from them. It should be noted that exercise in the evening, however, can cause sleep disturbances. Rhythmic aerobic and yoga exercises may be particularly helpful for combating stress, anxiety, and sleeplessness.

    What is a Calorie..And why should I care?

    The official definition of a calorie is "...the amount of heat needed to raise the temperature of a liter of water 1 degree (DHHS)." But if that's a little too scientific for you, think of it this way...

    A calorie isn't actually a tangible thing, it's a unit of measurement.

    A calorie measures the energy in food and beverages we take in. We all need that energy to live. Everything we do relies on the energy that comes in the form of calories.

    The food we eat becomes the fuel that runs our bodies. Drinks also contain calories; sodas, for example, are referred to as "empty calories" meaning they carry no other nutritional value; but the calories definitely still count.

    No matter the form of your calories ...

    if you "overload your tank" you will find yourself gaining weight.

    Understanding caloric needs is an integral part of weight loss. Research over the years has proven -- whether diets focus on fat or carbs -- that calories still count. Why? Regardless of what diet you're following, if you take in more calories than you need ... you gain weight.

    The daily recommended caloric intake for the average American maintaining their weight is 2,000 calories, give or take a few: Men can eat a little more, women, less. Your specific, individual calorie needs depend on several factors such as your activity level and metabolism.

    Where are Calories?

    Calories are found in four components of foods. They are: fat, carbohydrates, protein and alcohol (i.e., sugar). Fat contains twice the calories of carbohydrates or protein.

    Are All Calories the Same?

    It depends on who you ask. The overwhelming response among experts over the years has been a "calorie is a calorie is a calorie", that, no matter where your calorie comes from, it doesn't work any differently.

    There is a bit of controversy about whether or not a calorie's value can vary among particular foods or when people follow a certain diet.

    In a study that appeared in the professional publication, Nutrition Journal, "'A calorie is a calorie' violates the second law of thermodynamics," researchers go so far as to say that the "calorie is a calorie" theory is completely untrue and is an "old idea" that has helped to continue the obesity epidemic.

    But until medical science can prove there are different types of calories that bring different results, it's safe to assume that there aren't any variations.

    How do Calories Get Stored as Fat?

    We all have a basal caloric need that our bodies require each day to provide its minimum functions, including keeping our organs running.

    When you are in excess of that, your body doesn't have any choice but to do something with those extra calories. It puts them in storage in the form of fat.

    In other words, calories turn into fat when they're sitting around doing nothing. When you have taken in 3,500 calories above your caloric needs ... you gain a pound.

    Learn to Count Calories and You'll Lose Weight

    It follows that if it takes 3,500 extra calories to gain a pound, all it takes is to cut 3,500 calories to lose one. This is best achieved by cutting some calories from your regular diet with simple changes, such as choosing reduced-calorie beverages daily and burning additional calories by exercising on a regular basis.

    Reducing your caloric intake by and/or burning a total of 500 calories a day will lead to an average of one pound lost each week, a healthy and sustainable rate at which to lose weight. The most important thing to remember is to not cut calories too drastically. Not only can it "backfire" and actually prevent weight loss, doing so puts your health at risk.

    The History of Food Labels

    The History of Food Labels

    Food labels were regulated in 1994. Before then, food companies could print their products’ nutritional information basically anywhere they wanted to (and often in really small print).

    The Food and Drug Administration required companies to format the information in a structured way and to include helpful information on the label -- in a set size and organized manner.

    These regulations required both the ingredients and nutritional information to be provided along with a food label of a standard size and shape (a rectangle) labeled “Nutrition Facts”. In this box, you will find nutritional information listed in order of importance.

    In 1994, the FDA and U.S. Department of Agriculture required that:

    • labels provide information on how the food fits into an overall daily diet
    • labels will include information on the amount per serving of saturated fat, cholesterol, dietary fiber, and other nutrients of health concern to today's consumers
    • terms such as light," "fat-free," and "low-calorie" meet government definitions
    • be consistent across product lines to make comparison shopping easier
    • expressed in common measures
    • reflect amounts people actually eat (Good Reading)

    Serving Sizes

    Serving size is the first item listed on a nutrition label. Serving sizes are standardized, recommended snack or meal size portions. Depending on the type of food, the serving size may be indicated by cup measure or number, such as one cup of cereal or one slice of bread. Some foods, like salad dressing, can be represented by small measures like tablespoons. This information is followed by the metric amount (e.g., grams) the serving contains.

    Serving size is the most important part of the food label. It is integral to using the additional information on the label to lose weight. Whether you count calories, fat grams, or carbs, it is impossible to accurately track them without knowing and measuring serving sizes.

    The following items are indicated on all food labels:

    Percent Daily Value

    Sometimes referred to is DV, the Percent Daily Value displays the amount of nutrients found in each serving of the food such as calories, fat, cholesterol, sodium and vitamins. These values are set by the Food and Drug Administration.

    For example, a food that has 13g of fat per serving would state a 20 percent daily value on the label (Daily Values).

    Calories and Percent Fat Calories

    The calories in a serving are displayed directly under the portion sizes. The number of calories you actually take in is determined by the number of servings you eat.

    The FDA considers a food with 40 calories or less per serving to be low calorie; 100 calories per serving, moderate; and 400 calories or more per servings is a high calorie food (How to Understand).

    The food label assumes that the typical adult needs 2,000 calories a day to maintain his/her weight.

    Most people fall somewhere in the middle, with men requiring more daily calories than women to maintain their weight.

    It is recommended that your diet provides no more than 30 percent of total calories from fat (Choose a Diet). For a 2,000 calorie diet, no more than 600 calories of your day’s food intake should comprise of fat.

    Fat

    A food’s fat and saturated fat content is displayed next. Starting in 2003, the FDA added trans fat to the label and it became required in 2006. Some manufacturers also include monounsaturated and polyunsaturated fats on labels.

    Fat is listed in grams. Too much fat leads to overweight and obesity, however our bodies need some fat in order to function. For a 2,000 calorie diet, it means eating no more than 65 grams of fat each day.

    Saturated and trans fat are known as “bad fats” because they raise cholesterol and can lead to health risks such as heart disease.

    Unsaturated fat is a “good fat” that is healthy because it will not raise your cholesterol level. An example of a good fat is olive oil.

    Cholesterol

    Cholesterol is listed under fats. It is a fatty substance found in animal products such as meat and dairy products. Cholesterol is a major factor in the risk of heart disease and heart attack. The American Heart Association recommends that you limit your average daily cholesterol intake to less than 300 milligrams (Limiting Fats).

    Carbohydrates

    Carbohydrates -- often referred to as carbs -- are listed next. Carbohydrate is an energy source used for bodily functions for everything from just walking to intense, prolonged exercise.

    Carbohydrates from whole grain sources such as brown rice are preferable to those contained in refined carbohydrates such as white bread because of the way the body processes them.

    Unless you're following a low-carbohydrate diet, it is acceptable to eat up to 300 grams of carbohydrate each day.

    Protein

    Protein is used by the body to build cells and maintain muscle and other tissues. In the average American’s diet, it is mostly derived from meat, poultry, fish, and/or eggs. Dairy foods, beans and nuts also contain protein.

    Protein does not have a recommended daily value indicated on the food label.

    Protein needs are actually variable depending on your weight and activity level.

    Using Food Labels in the Real World

    The key part of using food labels is they provide instant portion control. The only way you can use food labels effectively is to measure and eat portions based on the recommended servings sizes.

    The good news is, in time, assessing the serving size of your favorite foods will become second nature.

    At first, measuring food servings will seem tedious, but it will not always be that way. Within a matter of weeks, you will learn to eyeball servings and practice automatic portion control.

    Once you assess your caloric needs, food labels will help you identify areas in which you can cut back painlessly and lose weight.

    For example, when you see your favorite yogurt contains 160 calories per serving, it will be much easier to identify one that contains 100 calories if you always check the nutrition label. If you eat yogurt every day, this one change can cut over 400 calories from your diet each week!

    Remember ... every 3,500 calories cut or burned equals one pound lost. A little light reading on the packages of your favorite foods could be the start to making it happen

    7 Ways to Triumph over Turkey Day

    ou -- yes, you -- can triumph over Thanksgiving weight gain! Check out these 7 simple ideas:

    1. Don't Save Up

      Don't save calories from earlier meals for "the big one." You'll inevitably get too hungry and overeat to compensate for missing those meals. Thanksgiving day should include a substantial, healthy breakfast and a normal lunch. Then, you won't be too famished to practice portion control when dinnertime arrives.
    2. Make Like a Rabbit

      That is, help yourself to a veggie-filled salad or raw vegetables, such as carrots and celery, before the main meal. Doing so will curb your appetite, provide you with extra nutrients, help you feel fuller later, and give you something to munch while others are eating high-cal hors d'oeuvres.
    3. Figure Out What's Filling

      If you don't know which dishes to avoid, think filling -- the ones you eat one serving of and think, "I couldn't eat another bite" (but usually manage to anyway). This includes high-fat casseroles, such as broccoli and cheese, cream-based soups, mashed potatoes, potatoes au gratin, stuffing, and dressing. In this case, the more filling, the more fattening.
    4. Drink Less Like a Fish

      If your family serves wine during Thanksgiving dinner, try to limit yourself to just the first glass. A few glasses add up to hundreds of calories. (According to Calorie Count Plus, three glasses of white wine serve up 210 calories!) Plus, drinking can actually stimulate your appetite, make you more likely to disregard portion control and less likely to say no to the dessert table. So after one glass, swap that glass of wine for a glass of water.
    5. Don't Sleep it Off

      Triptophan is a worthy adversary, but fight the urge to nap the evening away. Moving more than normal -- whether it be a game of touch football in the front yard, or a marathon of shopping on Black Friday -- will help compensate for any little indulgences that slipped by over the last couple of days.
    6. Eat Turkey Until You Never Want to See Another Turkey

      All those leftovers don't have to spell diet disaster. Turkey is a healthful, lean protein source that's perfect for healthy meals. Slices of turkey (without skin and gravy) with whole grain rice and steamed veggies makes a low-cal, well-rounded meal -- you can even save room for a tiny slice of Mom's pumpkin pie.

      A turkey sandwich on whole wheat with reduced-fat mayo, lettuce, tomato and baby carrots is a nutritious, diet-friendly lunch to use up more leftovers, or to enjoy year-round.

    7. Maintaining is Marvelous

      Don't worry about losing weight during the holidays. Resolve instead to maintain what you've already accomplished. In the end, staying right where you are on the scale is better than putting on a few pounds. Don't stress out over no net loss -- celebrate a lack of gain.

    One More Thing...

    Don't let yourself think a few Turkey Day slip-ups are cause to give up your weight loss efforts altogether. It's rather tempting to go back to eating all of your old favorite fattening foods after you've blown your diet a few meals in a row.

    But remember, you will look and feel better come January 1 if you get right back on the wagon and return to your new, improved eating habits. Happy Thanksgiving!
