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

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

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

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
