1. What exactly is metabolism.?
2. How does it affect people.?
3. What is the average metabolism of a 15 year old.? (if it has some sort of measurement)
4. Is it possible to raise or lower metabolism, and if so how.?

If you know of a website containing this information that would be great too.Health Question & Answer


Answers:
1. Metabolism is how fast your body can turn food sugars into energy and how quickly your body can use up that energy. A fast metabolism usually signifies that you can expend your energry easily and not gain weight easily.

2. Having a fast metabolism means that you can easily eat whatever foods you like without gaining weight. Those that have a slow metabolism will typically gain weight much easier from the foods that they eat (especially if it is "junk food")

3. Don't know exactly how to measure your metabolic rate...although I'm sure doctors may have a way to do it

4. As you get older, your metabolism slowly slows down. As you get older, you should be more watchful of what you eat and how much you eat and exercise daily.Health Question & Answer

Metabolism is the set of chemical reactions that occur in living organisms in order to maintain life. These processes allow organisms to grow and reproduce, maintain their structures, and respond to their environments. Metabolism is usually divided into two categories. Catabolism breaks down organic matter, for example to harvest energy in cellular respiration. Anabolism, on the other hand, uses energy to construct components of cells such as proteins and nucleic acids.Health Question & Answer
