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

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

The entire metabolic process is run by biological catalysts known as enzymes. They are long, chain-like protein molecules that are twisted into characteristic three-dimensional shapes. Enzyme molecule
s function rather like templates to hold reacting molecules together in the proper position to speed their interactions. If your enzymes lose their shape ("denature"), they stop functioning, your meta
bolism ceases, and you're dead. Birds are no different. That's why boiling kills; it denatures enzymes.

Dangerous side-effects for rasing metabolism -In America, some over-the-counter weight loss supplements contain thyroid extract from animals, or other substances that (supposedly) act like human t
hyroid hormones to speed up metabolism. -Reported side-effects of these products include: - Nervousness and tremors - Bulging eyes - Racing heart beat - Diarrhea - Excessive
sweating - And worse!

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).
