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!

The physical and chemical processes that maintain a life are called, collectively, its "metabolism." A flow of energy is required to run the metabolism of any organism, and the basic energy source for
all birds is the sun. Green plants "capture" the sun's energy in the process of photosynthesis, and birds then acquire it by eating plants or by eating other animals that eat plants. The energy is us
ed to do the work of building tissues, contracting muscles, manufacturing eggs, processing information in the brain, and powering all the other activities of a living bird

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.

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.

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

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!
