Drinking water before meals will obviously reduce food intake and change the desire for food, because with enough water, the body will prefer protein to carbohydrates.

Studies have shown that a glass of water can stimulate the sympathetic nervous system as high as 1. After 5~2 hours, the secreted adrenaline can gradually consume the fat stored in the body and obviously reduce the excess weight. Compared with dieting, the weight lost in this way is more stable and lasting.

2. Drink water in the afternoon to reduce fat.

The main manifestation of obesity is fat, which is caused by sedentary and high-calorie food. Afternoon is a time when people feel tired and tired, and this is a fragile moment when people consume unnecessary calories because of their emotions, which is easy to produce fat.

You can drink a glass of water to relieve your desire to eat and reduce your appetite.

3. Drink water before exercise at night to speed up excretion.

After dinner, you can go for a walk outside. Drinking some water at this time helps to excrete.

Extended data

1. First of all, control the diet, limit the total energy intake to 1000- 1500kcal/ day, and reduce the fat intake, which should account for 25%-35% of the total energy. The diet is rich in fruits, vegetables and dietary fiber; Lean meat and vegetable protein are used as sources of protein. There should be enough high-quality protein in the diet to lose weight. In addition to the necessary nutrition, it is also necessary to supplement the necessary vitamins, minerals and adequate water.

2, but also change eating habits, you need to chew slowly when eating, which can slow down the absorption of nutrients and control energy intake. The goal of diet control is to control the monthly weight loss at about 0.5 ~ 1 kg, and lose 7-8% in 6 months. Obese patients had better make a strict diet plan under the guidance of a special dietitian.

3. During exercise, the utilization of fatty acids and glucose in muscle tissue is greatly increased, so that excess sugar can only be used for energy supply and cannot be converted into fat storage. At the same time, with the increase of energy consumption, the stored adipose tissue is "mobilized" to burn for energy, and the adipose cells in the body shrink, thus reducing the formation and accumulation of fat. This can achieve the purpose of losing weight. Weight loss exercise should emphasize scientificity, rationality and individualization, and master the appropriate amount and degree of exercise according to its own characteristics.

4. At present, there are two kinds of drugs commonly used to treat obesity: one is appetite suppressants acting on the central nervous system: these drugs, also known as anorexics, reduce the reuptake of serotonin and norepinephrine by affecting the activity of neurotransmitters, thus reducing food intake, suppressing appetite and improving basal metabolic rate to lose weight, such as sibutramine.

5. There is also a lipase inhibitor that acts on the periphery: it can achieve the purpose of losing weight by blocking the absorption of some fat in the diet. For example, orlistat inhibits gastric lipase and pancreas in the gastrointestinal tract, thus reducing the fat absorption by about 30%. Patients who need medication have a body mass index greater than 30kg/m2 and no complications, or have other complications greater than 28kg/m2.
