In theory, you can lose weight by drinking only water for a week without eating. But this is only a theoretical data. In real life, this is not realistic. If you don't eat anything for a week, your body can't stand it. If you can really lose weight, it will not be worth the loss and will do great harm to your body.

Although you can lose weight without eating for a few days, your muscles will be melted away, which will affect your normal function, slow down your metabolism and hinder your weight loss. Moreover, once the diet is restored, it will rebound quickly.

The harm of dieting to lose weight is that it will directly hurt the stomach. Long-term dieting will lead to the decline of gastric motility and endurance. If you don't eat on time, there is no food in your stomach, which will directly stimulate your stomach to produce gastric acid. Over time, gastric vascular sclerosis will occur, causing various stomach diseases such as gastric ulcer.

People ensure a reasonable diet of three meals a day to obtain nutrients needed by the human body, such as protein, fat and minerals. Long-term dieting can easily lead to the lack of vitamins and trace elements, slow down the metabolic function of human body, lead to endocrine disorders and seriously affect health.
