The weight loss principle of high fat low carbon diet is mainly through strict control of carbohydrate intake, so that the body is in a state of starvation, thus accelerating the consumption of fat. Low-carb, high-fat diet for weight loss puts the body in a glucose-deficient starvation state, and under normal circumstances human movement and physiological activities require the consumption of a certain amount of glucose and fat to provide energy. If you strictly control the intake of carbohydrates, it will make the body in the glucose shortage into the fat consumption state, and then achieve the purpose of weight loss. In addition, low-carb, high-fat diet can also be called ketogenic diet, this is because fat consumption is easy to produce ketone bodies, but if the body generates too many ketones may exceed the metabolic capacity of the liver, which in turn causes ketoacidosis.
