First of all, exercise can reduce the secretion of insulin, a hormone that can store fat. If the secretion of insulin decreases, the storage of fat will also decrease. Exercise can effectively inhibit the secretion of insulin and promote the burning of "stored" fat like fuel. Insulin is a hot topic to lose weight now, because it can store fat. When the blood sugar concentration in the body rises. Insulin secretion increases, and sugar is "cleared" from the blood and sent to the liver to synthesize glycogen. Once the glycogen content in muscle and liver is saturated, the excess glycogen will be converted into fat and stored in the body fat layer in the form of triacylglycerol. If you don't exercise, liver glycogen will always be saturated, and more and more liver glycogen will be converted into fat and stored. Eating too much sugar for a long time will lead to high insulin level, and once the insulin level is high, you can't burn fat. At the same time, you will feel hungry, your liver will produce more cholesterol and your triglycerides will be higher. Therefore, if you want to lose weight and be healthy, you must control the secretion of insulin. The more you exercise, the more your blood sugar drops, the more fat you burn and the less insulin you secrete. In short, the tighter you control insulin, the less fat you store.
Secondly, exercise can increase the secretion of hormones that consume fat. Adrenaline and growth hormone are hormones that consume fat. During exercise, the content of these two hormones in the blood will increase, and the stored fat will burn like fuel. Adrenaline is mainly secreted by adrenal medulla, which can accelerate metabolism and burn body fat. Growth hormone can promote the growth of the body and release growth media through stimulation. Will affect the metabolism of protein, sugar and fat. The characteristic of growth hormone is that it can combine with receptors in human cells and play a role. There are also receptors for growth hormone in fat cells. Once growth hormone binds to the receptor in adipocytes, it will promote the decomposition of triacylglycerol in adipocytes and inhibit the absorption and accumulation of circulating lipids in adipocytes. Growth hormone can keep the blood sugar concentration in the body within the normal range. It is said that growth hormone can inhibit insulin, thus promoting the absorption of glucose by marginal tissues and strengthening the process of blood sugar synthesis in the liver. Growth hormone greatly accelerates the burning of fat by accelerating the decomposition and oxidation of triacylglycerol.
In addition, exercise can also accelerate basal metabolism. The more you exercise, the faster your metabolism, the more fat you burn, and the slimmer your body will be. The metabolic system is the engine in the body. When food is eaten, the metabolic system starts, or food becomes heat, or food becomes fat storage, or things that cannot be used become waste excretion. If you just eat and don't exercise, food will be converted into fat and stored; On the contrary, if you do moderate exercise, food will be immediately converted into calories and consumed, and there will be no excess fat.
