Dieting to lose weight is to control energy intake. There is little food supply every day, and the weight loss in the early stage is fast, but the human body is hungry for a long time and is easy to rebound. The ketogenic diet is a "simulated" hunger state, which only strictly controls the intake of staple food, but greatly increases the intake of fat. Carbohydrate: protein: fat ≈ 5%: 20%: 75%, so the energy intake can basically maintain the basic metabolism of the human body, and the human body will not feel too hungry, but also have a thin experience, and the rebound rate is much less.

Therefore, compared with dieting, the process of reducing weight by ketogenic diet greatly reduces the pain of hunger, and with the rapid weight loss, a large number of people naturally flock to it.

Ketogenic diet was first used in clinic, mainly used to treat epilepsy, allergic gastrointestinal syndrome, inflammatory gastrointestinal syndrome, ulcerative colitis, Crohn's disease, celiac disease and other diseases. In the process of treating these diseases, it is observed that patients will lose weight, so they are gradually used in weight loss research.

Generally, weight loss advocates controlling energy and fat intake, while ketogenic diet greatly increases fat intake. How can I lose weight? Two technical terms have to be mentioned here-gluconeogenesis and ketogenic reaction. Because the intake of carbohydrates is extremely low, which leads to insufficient carbohydrate energy supply, the body will heterogenize protein into carbohydrate energy supply, which is called gluconeogenesis. When the sugar substance is insufficient, fatty acids can not be completely decomposed to form a large number of intermediate products of fat metabolism-ketogenesis, which greatly improves the decomposition speed of fat. Therefore, this is actually a process of rapidly consuming and wasting fat. When there is no carbohydrate for energy supply, the fat stored in the body is mobilized for energy supply, and naturally you can lose weight quickly.
