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.

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

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!

How does Human Metabolism Work?- Thermic Effect of Food (TEF)
-The body uses energy to digest and absorb the nutrients present in the food we eat. The rate of energy used for the TEF is about 10%,
it can be increased depending on the composition of each meal.
-The TEF causes much confusion when dieters calculate calories in and out. For example;
-If we overeat the TEF actually increases
due to more food to digest, the stomach and intestines have to work harder and longer. It means if we ate an extra 3500 calories ( number of calories per pound of fat ) we wouldn't actually gain 1 pou
nd of body fat because the TEF has to be accounted for, we would gain less.
-The opposite also happens if we cut 3500 calories to lose 1 pound. The TEF decreases because there would be less food/n

An increase metabolism provides many benefits to help maintain continuous and permanent weight loss:
-less exercise would be needed - giving you more time
-less effort if you did exercise - no n
eed to try burning lots of calories during each session!
-less chance of weight regain later
-still enjoy some favorite foods - no need to be as strict on the diet
-less time spent preparing
low / non fat recipes and meals
-save money from not needing to buy all the expensive low fat varieties
-more chance majority of weight loss is fat rather than water

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
