BMR is much greater in childhood than in adulthood metabolism-thyroid-problems After thyroid-function the age of about 20, it drops about 2 per cent, per decade metabolism-thyroid-problems People whose bodies contain a higher proportion of muscle muscle to fat, tend to have a higher BMR than those with lower muscular proportions - all other things being equal metabolism-thyroid-problems What is thyroid-function the 'average' person's BMR? As a very rough guide, the thyroid-function the average person's BMR is about half a calorie per pound of body weight, per hour metabolism-thyroid-problems So, if you weigh 140 pounds you will use up approximately 70 calories an hour or 1680 1680 calories per day doing nothing metabolism-thyroid-problems thyroid-function The 5 things you need to know about BMR (1) The higher your BMR, the easier it is to lose weight All other things being equal, the thyroid-function the more energy your body 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 order to lose weight metabolism-thyroid-problems Thus a high BMR tends to make dieting and weight loss easier metabolism-thyroid-problems (2) Your BMR decreases when you go on a diet which has fewer calories than your thyroid-function your normal diet In response to fewer calories, thyroid-function the body lowers its BMR because it thinks there is a famine metabolism-thyroid-problems It therefore 'slows down' in order to conserve energy metabolism-thyroid-problems Hence the 'plateau' 'plateau' effect during dieting metabolism-thyroid-problems (3) Your BMR increases in response to increased physical activity Not only do we use up calories doing exercise but thyroid-function the increased BMR continues even after we have done done our exercise, often for several hours metabolism-thyroid-problems thyroid-function 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 metabolism-thyroid-problems calories metabolism-thyroid-problems Note: thyroid-function The exact reason why physical exercise leads to an increased BMR is not known metabolism-thyroid-problems The present consensus is that exercise preserves more of our lean body tissue metabolism-thyroid-problems Remember, the thyroid-function the higher our proportion of lean body tissue the higher our metabolic rate will be metabolism-thyroid-problems (4) Exercise is the ONLY effective way to increase your BMR Many diets claim to increase metabolic rate rate through special fat-burning exercises or fat-burning foods metabolism-thyroid-problems thyroid-function The truth is, your metabolic rate falls if you start dieting and start to shed excess pounds metabolism-thyroid-problems You may be able to reduce the thyroid-function 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 metabolism-thyroid-problems (5) Obesity is not caused by by a slow BMR Except in thyroid-function the rare cases of serious metabolic illness it is not possible to blame your metabolism for obesity metabolism-thyroid-problems Your metabolism certainly has an effect on how much you |
