The process of eliminating fat by the body

posted in: Diet | 0

All physique processes of the body demand power to be able to function effectively. Once the body is expending a lot more power than it can be consuming (e.g. when working out), the body’s cells depend on internally stored power sources, just like complex carbohydrates and fats, for energy. The initial supply to which the body turns is glycogen (by glycogenolysis). Glycogen is a complex carbohydrate, 65% of that is stored in skeletal muscles along with the remainder, within the liver (totaling about 2,000 kcal within the whole body). It is created from the excess of ingested macronutrients, mostly carbohydrates. When glycogen is practically depleted, the body starts lipolysis, the mobilization and catabolism of fat deposits for power. Within this method, fats, obtained from adipose tissue, or fat cells, are broken down into glycerol and fatty acids, which may be utilised to produce energy. The principal by-products of metabolism are carbon dioxide and water; carbon dioxide is expelled via the respiratory system.

Fats may also be secreted from the sebaceous glands (within the skin).
