Hunger diet may have obvious short-term effects and will definitely rebound, because no one insists on not eating. Even if you are hungry and thin, you may turn yourself into a fat body. For most people, the hunger diet is ineffective and the failure rate is high. 10 people lose weight, and maybe only one "wonderful flower" can starve. Even if you really rely on willpower to force yourself to be hungry, once you resume dieting, it is very easy to retaliate.

In the process of dieting and losing weight, water, excrement and fat are reversible and relatively easy to reproduce, while muscles are irreversible. When a muscle is lost, it is not easy to grow back. Muscle tissue is consumed and fat is not much reduced. Although the weight has decreased, the metabolic capacity has also decreased. Once the normal diet is restored, due to the decrease of basal metabolism, the upper limit is lowered, and what is eaten is converted into fat and bounces back.
