Does More Frequent Meals Really Rev Up Your Metabolism?

You’ve probably heard that eating smaller meals, several times a day will stimulate your metabolism, and keep it revved to burn more calories throughout your day.
…………….CLICK & SEE
The New York Times points out that although some studies have found modest health benefits to eating smaller meals, the research usually involved extremes.

Many weight-loss books and fad diets claim six meals a day is a more realistic approach.

But will it really make a difference?

The New York Times states:

“As long as total caloric and nutrient intake stays the same, then metabolism, at the end of the day, should stay the same as well. One study that carefully demonstrated this, published in 2009 in The British Journal of Nutrition, involved groups of overweight men and women who were randomly assigned to very strict low-calorie diets and followed for eight weeks. Each subject consumed the same number of calories per day, but one group took in three meals a day and the other six.

Both groups lost significant and equivalent amounts of weight. There was no difference between them in fat loss, appetite control or measurements of hormones that signal hunger and satiety. Other studies have had similar results.”

Exercise, on the other hand, seems to effectively increase metabolism according to studies.

Some Health Quaries & Answers

 

Not a death knell :
Q: My 54 year-old widowed mother has been diagnosed with diabetes. She works as a secretary. Following the diagnosis she has given up her job and sits at home staring at the television. She insists she is very sick.

A: The diagnosis may have been a shock and she may be feeling depressed. You have to explain to her that it is not a terminal disease. It can be easily brought under control with a 1,500 calorie diet, regular exercise (walking for 40 minutes a day) and the prescribed medication.

This way she can lead a long and healthy life. Failure to adhere to this may result in complications.

Fat, but can’t walk
Q: I have arthritis of the knees. Walking is painful, so I have been taking rest. In the process, I put on 15kg. Now the doctor says I must lose weight. I cannot walk. Dieting is not effective at all. What am I to do?

A: You can lose only a certain amount of weight with dieting alone. If you are sitting at home with nothing else to do, the hunger pangs can be devastating. You could purchase a recline exercise cycle. In that you actually sit with a backrest and cycle. It is easy on the knees. Two hours of cycling and a calorie-restricted diet will guarantee weight loss!

Do sunglasses help?
Q: Do wearing sunglasses in India help in any way?

A: Sunglasses are not just fashionable. Good quality glasses with ultra violet protection prevent premature ageing of the eye, cataract formation and yellowing of the sclera.

Stop smoking
Q: My leg feels numb and I cannot walk more than 100m without feeling pain. I am 26 years old and smoke around 20 cigarettes a day.

A: The nicotine and other poisonous chemicals in cigarettes constrict the blood vessels. When the main blood vessels are affected intermittent claudication (pain on walking a certain distance relieved by rest) develops. When the blood supply to the nerves is affected tingling and numbness develops. It is better for you to stop smoking altogether. It offers no benefits, is expensive and in your case is adversely affecting your health.

Lots of red blood cells
Q: I have been suffering from drowsiness and feel uneasiness in the chest in the morning hours. I have consulted doctors and after various pathological tests found that I have excessive haemoglobin (last test reveals 21.0 g/dl). I was told I had polycythemia and was advised to remove 250ml of blood from my body twice a week. This is frightening and I do not understand why a high haemoglobin count is considered bad and not healthy.

A: Polycythemia is a condition in which there is a net increase in the total number of red blood cells in the body. This may be a response to low oxygen levels in the body as a result of smoking, renal or liver tumours, haemangioblastomas in the central nervous system, heart or lung diseases, or endocrine abnormalities. It can occur in athletes who dope themselves with high testosterone levels. High levels of haemoglobin increase the viscosity of the blood. This can lead to blockages and strokes. If you live at a high altitude, are a smoker, or have any of the correctable causes listed above, you can be cured once the underlying disease is treated. Otherwise removal of the blood at regular periodic intervals is the only solution.

Help, I’m bald
Q: I have lost a great deal of hair and am now bald. Can I use minoxidil?

A: Hair loss and hereditary baldness do respond to minoxidil. The problem is that the lotion has to be applied regularly. The hair which grows is fine and silky (lanugo hair) and tends to fall out soon after the applications are stopped.

Six Pack Abs

[amazon_link asins=’B004L6ZY3W,B0042AGNB4,B014VB6OYO,B01D95D64O,B01LZI0685,1520919328,B007PRQ5J6,B01N0DUF3N,1516975553′ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’068e48e4-4677-11e7-8ab4-7bd14057a38b’]

Gone are the days when a paunch, a plump wife and a couple of well-fed children were signs of success. The “now “ generation follows the fashion trends of its idols (the Khan brigade of Aamir, Shah Rukh, Salmaan and a few others in Bollywood) and everyone wants a six pack, or at least a four pack ab. Such ambition is not the prerogative of men alone. Women too want a midriff that can be bared and need not be concealed under voluminous folds of chiffon.
...CLICK & SEE THE PICTURES
The concept is simple. Just strengthen the abdominal muscles and lose body fat. What could be easier?

The catch lies in putting the equation to action. If your job and personal monetary value rest on your appearance (as with models and movie stars), many hours a day can be dedicated to achieving and maintaining this goal. Personal trainers, physiotherapists, physicians and dieticians can be employed.

For most people, an hour a day is about all they can spare, and the household income will not support the services of additional helpers.

With patience, dedication and will power, a six pack is an achievable objective and the effort is well worth it. Your morale, and physical and mental health will improve. An added bonus — despite your age, heads will turn.

The first step is often the most difficult — to get off the couch, put down the TV remote and start exercising.

When you eventually do get a six pack, the idea is that it should be seen and appreciated. This will not happen if it is hidden under a layer of body fat. Priority one is, therefore, to get rid of that flab. To do this, cardiovascular exercises like running, swimming, cycling, skipping or stair climbing for at least 20 to 30 minutes have to be combined with muscle training. Ideally the cardiovascular exercise should be performed after weight training. Having a light tea or coffee before starting also kick starts the metabolism.

Weight training increases muscle mass, calorie consumption at rest and reduces flab. Around 20 repetitive movements with a light weight (1-5kg) for each group of muscles is usually sufficient. This will not result in huge bulging muscle masses as in body builders.

Abdominal exercises have to be repeated at least every other day to maintain muscle tone. Exercises involve lying on the floor with the knees bent and then trying to touch the knee with the nose, bringing the knee up to touch the nose or moving both together simultaneously to meet in the middle. Start with 20 repetitions and eventually work up to 500 of each exercise set, increasing the number done only once a week. The most efficient abdominal exercise is cycling in the air.

While performing any manoeuvres, protect the neck. Do not attempt to place the fingers behind the head and pull up using arm strength. Place the arm across the chest or else place just the tips of the fingers behind the ears. Also, make the movements smooth and fluid. Jerky jack knife movements can injure the lower back.

Exercise does not really have to be a “no pain, no gain” process. Activities like flexing, stretching, clenching and unclenching the stomach while sitting behind a desk (especially if your job is sedentary) will effortlessly go a long way to achieving a flat stomach.

The abdominal machines advertised on television are really not worth the money. Similar results can be achieved with persistence. Targeting just a specific area of your body and doing exercises only to reduce fat from that particular region does not work. Dieting, exercising and working out have to be combined to get the ideal shape. Space out calories in 3-4 meals instead of missing a meal altogether. Try eating a fruit or drinking a large glass of water before a meal. Both will curb the appetite and offer health benefits as well.

Snacking on high calorie foods is unhealthy and silently adds to the number of calories consumed. Even when the meals actually eaten are small, there is no weight loss and the paunch remains. A written record of the food eaten and exercise done will help to keep a reality check on intake and output.

Many supplements (pills, powders, liquids) are advertised as the magic cure for increasing muscle mass and/or weight loss. They are expensive and the claims misleading. Thyroid tablets (to increase the metabolism) and anabolic steroids (for muscle) or diuretics (to lose water) are dangerous. There are specific appetite suppressant drugs that can be taken under strict medical supervision. Adjuvants will work only if combined with diet and exercise.

Everyone has an opinion on diet, exercise and body sculpting. Listen to these opinions, settle on a routine that works for you, and, remember, working out is like having a job. You cannot “take off” too many days without losing out.

Eating less, exercising more equally good

 Eating less and exercising more are equally good at helping take off the pounds, US researchers said on Friday in a study that challenges many of the popular tenets of the multibillion dollar diet and fitness industry…..click & see

Tests on overweight people show that a calorie is just a calorie, whether lost by dieting or by running, they said.

They found there is no way to selectively lose belly fat, for instance, or trim thighs. And their carefully controlled study added to evidence that adding muscle mass does not somehow boost metabolism and help dieters take off even more weight.

“It’s all about the calories,”said Dr. Eric Ravussin of the Pennington Biomedical Research Center, part of Louisiana State University in Baton Rouge.

“So long as the energy deficit is the same, body weight, fat weight, and abdominal fat will all decrease in the same way.”

Ravussin said the study, published in the Journal of Clinical Endocrinology & Metabolism is one of the few done under controlled conditions that can actually show what happens to a human body while dieting and exercising.

Ravussin’s team has been testing volunteers for another reason — to see if taking in fewer calories helps people live longer.

Strict diets have been shown to help animals from worms to dogs live longer, but it takes longer to study monkeys and humans.

They tested 24 people, 12 who ate a calorie-restricted diet, and 12 who dieted and also exercised five times a week for six months.

The dieters ate 25% less than normal, while the exercisers reduced their calorie intake by 12.5% and increased their physical activity to lose an extra 12.5 in calories.

Another 10 volunteers acted as controls. All food was provided in carefully measured portions for most of the study.

The volunteers in both groups lost 10% of body weight, 24% of fat mass, and 27% of abdominal visceral fat. Visceral fat is packed in between the internal organs and is considered the most dangerous type of fat, linked with heart disease and diabetes.

The distribution of the fat on the body was not altered by either approach — helping prove that there is no such thing as “spot reducing”, Ravussin said in a telephone interview. This suggests that “individuals are genetically programmed for fat storage in a particular pattern and that this programming cannot easily be overcome”, he added.

Ravussin has published other studies that also dispute the idea that exercise builds muscle that helps people lose weight.

“If anything, highly trained people are highly efficient, so they burn fewer calories at rest,”Ravussin said. Dieting alone also did not appear to cause the volunteers to lose muscle mass along with fat, Ravussin’s team found.

“There is a concept that if you exercise, you are going to lose less of your muscle,”he said. But his team found no evidence this is true.
