Dear student
Metabolism is a termed in which the food that we intake is changes to energy. The sum total of all the chemical reaction ocuring in our body is metabolism.During the complex metabolism biochemical process, calories in food and any potable liquid are combined with oxygen to release the energy that our body require to do any work and function. When we are at resting position , our body burns number of resting metabolism.Muscles burns more calories than fat so when we are with excess weight our resting metabolism is slower than those who has more muscle mass.So , in this way efficient metabolism is needed to affect body weight and body function.
