Control calorie intake: protein and cellulose are the main daily intake, and sugar, fat and fresh water compounds are strictly controlled. For example, Mayweather's daily diet is high in protein, no fat and no carbohydrates. To put it simply, the mainstream is to eat boiled chicken breast, tomatoes, cucumbers and carrots, but not rice and pasta, high-sugar fruits such as desserts, watermelons and apples, and drinks such as cola and yogurt.

Lose weight before the game: this is mainly to eliminate water in the body. Generally, drink more water and urinate more on 1 day. Drinking water in half the next day, the body will continue to urinate a lot. On the third day, drinking water will be halved, and the body will still urinate a lot. Drink a little water on the fourth day, no water on the fifth day, and sweat in the sauna. The sixth day is the lightest day, and then I start drinking sports drinks to regain my weight. Play games on the seventh day.
