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.

Speed Up Metabolism
-Increasing the speed of our metabolism is probably one of the easiest ways to lose weight naturally.
-Speeding up the metabolism creates some benefits that will maintain we
ight loss progress.
-less exercise would be needed - giving you more time
-less effort if you do exercise
-less chance of weight regain after dieting
-still enjoy some favorite foods
-l
ess time spent preparing healthy low fat meals
-save money from not buying all the expensive low fat varieties

Effective fat loss cannot occur when the metabolism is low!
-Its a physiological fact that when losing weight we also lose protein from muscle. The faster the weight loss the more protein is used f
or energy and/or protein synthesis and a net loss of protein will always decrease the metabolism.
-As protein is lost from cells it gradually lowers the total lean body weight, this affects the bo
dy composition and lowers the metabolism. As this occurs it means we gradually require less calories to maintain weight so if the present diet is continued results will eventually stop, its even possi
ble to slowly GAIN back weight that was previously lost!

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).

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!

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.
