Anabolism is a succession of chemical reactions that build molecules from smaller components and usually require energy. Anabolism allows the body to grow new cells and maintain all the tissues.

Catabolism is a series of chemical reactions that break down complex molecules into smaller units and usually release energy. Catabolism provides the energy our bodies need for all its activities.

It's a result of the amount of energy we release into our bodies (catabolism) minus the amount of energy our bodies use up (anabolism). The excess energy is stored either as fat or glycogen in the muscles and liver, with fat being the most caloric dense of the two.
