Losing weight is first of all willpower. You need to understand why people are fat or thin, that is, whether they consume more or less energy than they consume. If you consume more energy than you do, you will be fat; if you consume less energy, you will be thin. That way is to reduce energy intake and increase energy consumption. Increasing energy consumption means increasing exercise intensity. You can jog in the morning and evening or go to the gym to exercise. I think it is more important to reduce energy intake, which can guarantee to lose weight in a short time and achieve the goal of losing weight. It is not recommended to reduce the amount of food to lose weight. After changing my diet, my habits have become better. I also achieved the goal of losing weight by reducing meat and increasing vegetarian diet. Eat well in the morning, milk, bread and eggs are no problem, and eat a little at noon, mainly vegetarian. Eat as little as possible at night, light, mainly low-calorie foods such as fruits. If you used to eat meat every day, it is recommended to eat it two or three times a week for Chinese food. In this way, the whole calorie intake will be reduced a lot, and the obvious effect will be seen in two months in college. There is no shortcut to lose weight, and all weight-loss advertisements are at the expense of hurting the body and wasting money.
