There are many reasons for easy rebound after losing weight, one of which is that diet and exercise habits have not changed during weight loss. When people start to lose weight, they usually change their eating habits and exercise habits to reduce calorie intake and increase calorie consumption. However, once they reach their weight loss goal, they may return to their original diet and exercise habits, which will lead to a weight rebound.

In addition, people usually take some extreme ways to lose weight in the process of losing weight, such as dieting, exercising a lot, using diet pills and so on. These methods seem to be able to lose weight in a short time, but they are extremely suppressing their willpower or appetite. Once they return to normal, they will overeat and gain weight.
