How does Human Metabolism Work?- Thermic Effect of Food (TEF)
-The body uses energy to digest and absorb the nutrients present in the food we eat. The rate of energy used for the TEF is about 10%,
it can be increased depending on the composition of each meal.
-The TEF causes much confusion when dieters calculate calories in and out. For example;
-If we overeat the TEF actually increases
due to more food to digest, the stomach and intestines have to work harder and longer. It means if we ate an extra 3500 calories ( number of calories per pound of fat ) we wouldn't actually gain 1 pou
nd of body fat because the TEF has to be accounted for, we would gain less.
-The opposite also happens if we cut 3500 calories to lose 1 pound. The TEF decreases because there would be less food/n

From the viewpoint of diet and weight loss, metabolism is the process whereby the body converts food into energy (or uses it for bodily repairs) or stores it as fat for future use. In simple terms, if
we have a faster metabolism we burn calories more efficiently and store less fat. If we have a slower metabolism we burn calories less efficiently and therefore store more calories as fat. In very si
mple terms, our Metabolic Rate is the rate (and efficiency) with which our body performs these metabolic tasks.

What is the 'average' person's Basal Metabolic Rate (Metabolism) ?
-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 you will use up approximately 70 calories an hour or 1680 calories per day doing nothing.

Increasing the metabolism is the fastest way to permanent weight loss, a lowered metabolism is very often the reason weight loss progress grinds to a sudden halt. When weight loss slows a dieter may r
educe food intake further, however progress is still slow because a net loss of protein continues to lower the metabolism.

An increase metabolism provides many benefits to help maintain continuous and permanent weight loss:
-less exercise would be needed - giving you more time
-less effort if you did exercise - no n
eed to try burning lots of calories during each session!
-less chance of weight regain later
-still enjoy some favorite foods - no need to be as strict on the diet
-less time spent preparing
low / non fat recipes and meals
-save money from not needing to buy all the expensive low fat varieties
-more chance majority of weight loss is fat rather than water

living things must have an unceasing supply of energy and matter. The transformation of this energy and matter within the body is called metabolism.
-Catabolism
-Catabolism is destructive metab
olism. Typically, in catabolism, larger organic molecules are broken down into smaller constituents. This usually occurs with the release of energy (usually as ATP).
-Anabolism
-Anabolism is co
nstructive metabolism. Typically, in anabolism, small precursor molecules are assembled into larger organic molecules. This always requires the input of energy (often as ATP).
