How is human body fat formed? How to spend?

Most of the fat is digested and absorbed by the small intestine, so we know why we are pregnant! The environment in the stomach is acidic, which is not conducive to the digestion of fat. In the alkaline environment of small intestine, combined with the action of some digestive enzymes and the peristalsis of the intestine itself, fat is first decomposed into tiny latex, and then decomposed into fatty acids and glycerol again, and enters the blood circulation along the intestinal wall through the lymphatic system for consumption by the body.

When a lot of energy is consumed, the fat in adipose tissue will be mobilized and decomposed into fatty acids and glycerol under the action of enzymes. Then a series of oxidation reactions occur, producing energy, carbon dioxide and water. Energy is used for physical activities, and carbon dioxide and water are excreted mainly through breathing, sweat and urine.

If you want to consume excess fat in your body quickly, you must break this balance, that is, control diet and exercise consumption.

Expand the data of human body fat, that is, fat in the popular sense. Of course, human body fat not only refers to the fat that we can see externally, but also many things that we can't see. Fat is emulsified into small particles by bile. Lipases secreted by pancreas and small intestine hydrolyze fatty acids in fat into free fatty acids and monoglycerides (occasionally completely hydrolyzed into glycerol and fatty acids).

Hydrolyzed small molecules, such as glycerol, short-chain and medium-chain fatty acids, are absorbed by the small intestine and enter the blood. After monoglycerides and long-chain fatty acids are absorbed, triglycerides are first synthesized in small intestinal cells, and form chylomicrons with phospholipids, cholesterol and protein, which enter the blood circulation from the lymphatic system.
