Even if more exercise is undertaken a net loss of protein can occur if calorie intake is low.
-Remember dieters reduce their calorie intake but exercise uses extra carbs so the body must breakdown
extra protein to convert into carbohydrates. More carbs are needed because a less fit individual often has an untrained cardiovascular system and cannot supply enough oxygen for cells to burn fat for
energy during the exercise. Also if no exercise is performed the body has no need to use extra body fat because so little energy is required when inactive.
-Exercise can increase metabolism but the
trick for the unfit person is to perform the correct exercise and not cut calories too much too soon. To lose FAT weight fast the best way is to prepare the body by increasing the metabolism BEFORE c

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.

How does Human Metabolism Work? - Resting Metabolic Rate (RMR)
-This is the amount of calories needed to run all essential functions and chemical reactions while in a rested and quiet state. RMR is
the largest part of total metabolism and accounts for 65 - 75% of calories burned in a day.
-If lean weight is lost from the body through increased protein metabolism the RMR decreases. This often
happens when people go on a strict diet, the body is forced into what's known as a "negative nitrogen balance" which means more protein is lost than what is replaced due to less protein/energy intake
. This imbalance causes a gradual loss in lean weight thus lowering the RMR.
-Many dieters limit the amount of lean weight loss with some type of intense exercise in order for muscles to develop a

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

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).

The 5 things you need to know about Basal Metabolic Rate (Metabolism)
-(1) The higher your BMR, the easier it is to lose weight
-(2) Your Basal Metabolic Rate decreases when you go on a diet wh
ich has fewer calories than your normal diet
-(3) Your BMR increases in response to increased physical activity
-(4) Exercise is the ONLY effective way to increase your BMR
-(5) Obesity is no
t caused by a slow BMR
