Plan to
Increase Metabolism
In very simple terms, your metabolism is the rate at which your
individual body burns up energy in your diet plan. Metabolism varies from person to
person. You may have a faster metabolism than normal, for a person
of your size, or a slower one in your diet plan.
Basal Metabolic Rate (BMR)
In order to compare one person's metabolism with another's,
scientists have devised a new buzz word - basal metabolic rate (BMR).
Your BMR is the metabolic rate at which you use up energy when at rest -
e.g. when you are sleeping or just lying in bed. You might call it
your tick over speed.
The more you weigh the higher your BMR will be. The metabolic rate
of very fat women is 25% higher than that of thin women.
BMR is much greater in childhood than in adulthood. After the age
of about 20, metabolic rate drops about 2% per decade.
People whose bodies contain a higher proportion of muscle to fat,
tend to have a higher BMR than those with lower muscular
proportions - all other things being equal.
What is the 'average' person's BMR?
As a very rough guide, the average person's BMR is about half a
calorie per pound of body weight, per hour. So, if you weigh 140
pounds your metabolic rate will use up approximately 70 calories an hour or 1680
calories per day doing nothing.
The 5 things you need to know about BMR
- The higher your BMR, the easier it is to lose weight
All other things being equal, the more energy your metabolic rate needs in
order to tick over, the more food you can eat without gaining
weight - or conversely, the less reduction in food you need to
make in order to lose weight. Thus you increase metabolism which tends to make
dieting and weight loss easier.
- Your BMR decreases when you go on a diet plan which has fewer
calories than your normal diet plan
In response to fewer calories in your diet plan, the body lowers its BMR because it
thinks there is a famine. It therefore 'slows down' in order to
conserve energy. Hence the 'plateau' effect during dieting.
- Your BMR increases in response to increased physical activity
Not only do we use up calories doing exercise but the increased
BMR continues even after we have done our exercise, often for
several hours. The amount of increase varies from person to person
but even a modest increase should counteract the body's tendency
to decrease BMR when we cut calories.
Note: The exact reason why physical exercise leads to an increased
BMR is not known. The present consensus is that exercise preserves
more of our lean body tissue. Remember, the higher our proportion
of lean body tissue the higher our metabolic rate will be.
- Exercise is the ONLY effective way to increase metabolism
Many diets claim to increase metabolic rate through special
fat-burning exercises or fat-burning foods. The truth is, your
metabolic rate falls if you start dieting and start to shed excess
pounds. You may be able to reduce the extent of the fall by
increased exercise but there is no evidence whatsoever that your
metabolic rate will be higher than it was before you dieted.
- Obesity is not caused by a slow BMR
Except in the rare cases of serious metabolic illness it is not
possible to blame your metabolism for obesity. Your metabolism
certainly has an effect on how much you weigh but the main reasons
lie elsewhere.
