First of all, meat is rich in protein, which makes you feel full and can control the rise of blood sugar.

Meat provides rich protein, 100g lean meat can provide about 20g protein, and enough protein in the diet can provide a longer satiety, so that your appetite will not grow wildly and you will not fall into the situation of disorderly eating. Moreover, the compound diet rich in protein can delay the increase of postprandial blood sugar, reduce the secretion of human insulin and inhibit the synthesis of fat. In addition, maintaining normal basal metabolism and repairing body tissues also need the participation of protein. If you don't eat meat at all, you need to eat more staple food to make up for protein, and the utilization rate of plant protein is often not as high as that of animal protein.

Secondly, meat is rich in vitamins that promote the metabolism of the new city.

Meat is rich in B vitamins, especially vitamin B 1 (which is high in pork), nicotinic acid, pantothenic acid and folic acid. They are all essential nutrients for human body's heat metabolism. Without them, the calories you consume are hard to consume, and will eventually turn into fat accumulation. Meat can also provide vitamin B 12, which is rare in plant foods. Long-term lack of vitamin B 12 will cause megaloblastic anemia and seriously threaten human health. Of course, whole grains are also the main source of B vitamins, but now people eat staple foods too carefully, and most B vitamins are lost in vain.

Third, meat regulates blood pressure and blood lipids and prevents chronic diseases.

Meat can also provide essential fatty acids. Not all meat is saturated fat. In fact, lean meat contains quite a lot of monounsaturated fatty acids and omega-6 polyunsaturated fatty acids. The former is the kind of fatty acid mainly contained in olive oil, which is similar to olive oil, especially poultry fat. The latter is one of the essential fatty acids for human body, which helps to regulate blood pressure and blood lipid, prevent chronic diseases and reduce the immune burden. Those who lose weight with a lot of exercise often have a heavy immune burden.

Finally, meat is rich in iron and zinc, without which it is difficult for the human body to lose weight.

Meat can provide rich iron and zinc, and its absorption rate is higher than that of plant food. It is difficult to lose weight because iron is the carrier of oxygen in the body. Iron deficiency will lead to insufficient oxygen supply in the body, and insufficient lipolytic enzyme activity will make it difficult to burn fat, slow down basal metabolism and even reduce visceral function. Moreover, people with iron deficiency are prone to fatigue and it is difficult to keep exercising. Zinc, known as the "life element", is also very important to lose weight. Zinc is the raw material for synthesizing insulin, which controls the blood sugar balance of human body, and stable blood sugar plays a vital role in losing weight. Zinc can also promote gastric acid secretion and help protein digest and absorb it. In addition, it also participates in the metabolism of protein, protects and repairs human DNA, maintains the normal metabolism of human cells, and makes you thin and beautiful.
