All activities of the body require energy, and all needs are met by the consumption of food containing energy in chemical form. The human diet comprises three main sources of energy: carbohydrates, proteins, and fats. Of these three, carbohydrates most readily provide the kind of energy needed to activate muscles. Proteins work to build and restore body tissues. The body transforms chemical energy derived from food by the process of metabolism, an activity that takes place in the individual cell. Molecules of the food substances providing energy pass through the cell wall. Inside the cell, chemical reactions occur that produce the new forms of energy and yield by-products such as water and waste materials; see also adenosine triphosphate.
energyThe capacity to do work, measured in joules Types Potential/stored energy, kinetic/in motion energy. See Activation energy, Adaptation energy, Binding energy, Biomass energy, Bond dissociation energy, Department of Energy, Orgone energy.
energyThe capacity of a body to do work. Energy occurs in several forms-potential as in a compressed spring or a mass in a high position, kinetic as in motion, chemical as in petroleum and nuclear as in the binding forces of the atomic nucleus. Its effect, when manifested, is to bring about a change of some kind. The term is also used metaphorically to refer to human vitality and appetite for exertion or work.
energythe capacity of a body or system to do work. The most important energy forms, as far as living organisms are concerned, are heat, radiant, chemical and mechanical energy. Energy units of importance are:
The quantity of solar energy entering the earth's atmosphere is 64.3×108 J m-2 yr-1. The amount of solar energy available to plants in Britain is 10.5×108 J m-2 yr-1. The SI UNIT of energy is the joule (J). In plants and animals, energy is stored in ATP (short-term storage), and starch and FAT (long-term storage).

Q. Is energy drinks really boost my energy? Now-a-days the sale of the energy drinks have grown high. Is energy drinks really boost my energy?
Energy drinks are not necessarily bad for your health. But you shouldn't see them as some "natural" energy boost — the boost they give is from caffeine. Some of the claims made by manufacturers of energy drinks — such as "improves performance and increases concentration" — can be misleading.
Consider a better way to boost your energy: Get adequate sleep,
