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

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.

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

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.

Factors that affect speed of metabolism
-BODY SIZE:
-WEIGHT GAIN
-BODY COMPOSITION:
-SEX:
-AGE
-DRUGS
-HEREDITARY
-HORMONES
-PSYCHOLOGICAL STATE
-TEMPERATURE

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 rate at which you use u
p 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 wom
en is 25% higher than that of thin women.
- BMR is much greater in childhood than in adulthood. After the age of about 20, it drops about 2 per cent, per decade.
- People whose bodies contai
n a higher proportion of muscle to fat, tend to have a higher BMR than those with lower muscular proportions - all other things being equal.
