This eating habit actually limits the intake of fatty foods and starchy foods, which can play an ideal role in losing weight.

2. Disadvantages of the valley-avoiding diet:

(1) Easy to rebound: Going through the valley to lose weight is to achieve a certain weight loss effect through fasting or excessive dieting. This is a Taoist regimen. You don't eat anything for a certain period of time, so that your body is hungry to burn fat and achieve the purpose of losing weight. Only this method, once a little careless in diet, will easily lead to a rebound.

(2) Hypoglycemia: It is precisely because the purpose of losing weight is mainly achieved through fasting or excessive dieting that the basic nutritional needs of the body will inevitably be in short supply. At this time, the body may have hypoglycemia symptoms, such as dizziness or anemia. These are very common health risks caused by weight loss, so this method is not recommended for some friends with poor health.
