Chapter 17 How Exercise Burns Fat
When it comes to losing weight, exercise is inevitable.In fact, the essence of weight loss is to burn off excess fat.So how exactly does exercise burn fat?

First, exercise reduces the secretion of insulin, a fat-storing hormone. When insulin secretion decreases, fat storage also decreases.Exercise can effectively curb the secretion of insulin, prompting the "stored" fat to be burned like fuel.Insulin is a hot topic right now for weight loss because it stores fat.When the blood sugar concentration in the body rises.The secretion of insulin increases, which "removes" sugar from the blood and sends it to the liver to synthesize liver glycogen.Once the amount of glycogen in the muscles and liver reaches saturation, excess liver glycogen is converted into fat and stored in the body fat layer in the form of triacylglycerol.If you don't exercise, liver glycogen is always in a saturated state, and more and more liver glycogen will be converted into fat and stored.Long-term intake of too much sugar will lead to high insulin levels, and when insulin levels are high, you will not be able to burn fat.You'll also be hungry, your liver will produce more cholesterol, and your triglycerides will be higher.Therefore, if you want to lose weight and want to be healthy, you must control the secretion of insulin.And the more exercise you do, the more your blood sugar drops, the more fat you burn, and the less insulin you secrete.In short, the tighter your insulin control, the less fat you store.

Second, exercise can increase the secretion of fat-consuming hormones.Adrenaline and growth hormone are fat-burning hormones.When you exercise, the levels of these two hormones in the blood increase, which burns stored fat like fuel.Adrenaline is mainly secreted by the adrenal medulla, which can speed up metabolism and burn fat in the body.Growth hormone stimulates body growth by stimulating the release of growth interferon.It will affect the metabolism of protein, sugar and fat.The characteristic of growth hormone is that it can bind to the receptors in human cells and then exert its effect, and there are growth hormone receptors in fat cells.Once growth hormone binds to receptors in fat cells, it promotes the breakdown of triglycerides in fat cells and inhibits fat cells from absorbing and accumulating circulating lipids.Growth hormone keeps blood sugar levels in the body within the normal range.It is said that growth hormone has the function of inhibiting insulin, thereby promoting the absorption of glucose from limbic tissues and enhancing the process of blood sugar synthesis in the liver.By accelerating the breakdown and oxidation of triacylglycerols, HGH greatly accelerates fat burning.

In addition, exercise can also accelerate the basic metabolism.The more you exercise, the faster your metabolism will be, and the more fat you will burn, the slimmer you will be.The metabolic system is the engine in the body. When food is eaten, the metabolic system starts to turn food into heat, store it as fat, or excrete unusable things as waste.If you just eat without exercising, the food will be turned into fat and stored; on the contrary, if you do a moderate amount of exercise, the food will be immediately converted into heat and consumed, and no excess fat will be generated.
