Metabolism is the sum of all the chemical reactions involved in the continual process of breakdown and renewal in the body. Metabolic processes result in growth, produce energy, eliminate wastes and control other body functions, which distribute nutrients in the blood after food is digested.

A steady state is maintained by Metabolism in the body. Enzymes are important because they act as catalysts in making one chemical from another in the process of metabolism. Basal metabolism rate is important aspect of diet and related effects. Because individuals metabolize food differently, the foods and supplements that are beneficial to one person are literally dietary poison to another.

Metabolism is controlled primarily by two body systems: the oxidative system and autonomic system. The oxidative system converts nutrients into energy. Some individuals have oxidative systems that work quickly, while other people's oxidative systems work slowly. The autonomic system controls the use and distribution of energy. The important thing to be understood here is that we have to discard only the excess fat from the body and protect other useful cells of the body instead of becoming a victim of malnutrition. It is indeed very difficult to provide an accurate estimate of the exact rate of weight-reduction.

Some times, in the beginning, the amount of water and fluids in the body may go down quickly and therefore it appears that the weight is reducing fast but after three to four days the rate of weight-reduction decreases.

Exercises, diet, physical activity helps you to improve basal metabolism. Discarding extra fats, low intake of carbohydrates may help you result into weight loss. Drugs like thyroid group, in almost all the cases, the weight starts increasing after the withdrawal of drugs.
