Metabolism Information

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).

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.

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.

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

How does Human Metabolism Work?- Physical activity
The amount of energy the body burns during daily activities such as exercise, recreation, work, housework, etc. Daily physical activities accoun
t for 20 - 40% of calories burned each day. This part will vary depending on the individual and how active they are each day. A sedentary person will require less calories to maintain weight than a bu
sy worker in a construction site!

Increase the metabolism for less chance of water weight loss!
-If more protein is lost more water is also lost because protein holds four times its weight in water. Think about if a person lost 5 p
ounds in a week, that would require an extra 17500 calories so how could all this weight possibly be fat. In fact over a week only about 1 pound of the 5 pounds lost would be fat, the rest would be mo
stly water!
-Protein and its fluid replacement is the main reason many dieters regain weight after a diet. Again think about if someone regained 4 pounds in a week then does it mean that person has
eaten an extra 14000 calories?
-Increasing the metabolism means the body has a reason to hold onto protein thus less water is lost
