Ketogens can lose weight quickly, without too much exercise and hunger, and only need to change the eating structure to achieve the purpose of losing weight. Ketogenic diet replaces glucose by eating less carbohydrates, proper amount of protein and a lot of fat, providing energy for the body, thus producing ketones. In the process of eating a lot of fat, there is no strong hunger, and the body maintains normal operation by consuming fat. The effective time of ketogenic diet depends on the dieter's own diet and intake times.

Through low-carbon water diet or even low-carbon water diet, the body is forced to get rid of the mode of ingesting carbohydrates and then converting them into sugars to provide energy for the body, and instead use ketones generated by the decomposition of fat by the liver to provide energy, and even finally achieve the goal of completely getting rid of the sugar energy supply cycle. This way will make the body enter a physical state called ketosis, and at the same time, the body will have symptoms of weakness of limbs, dizziness and headache, which is risky. Therefore, it is recommended to try under the guidance of a doctor or a professional.

Ketogenic diet theory is to end the physiological metabolic pathway of glucose and use ketone body as the source of body energy instead. When the intake of carbohydrates is limited to less than 20 grams a day, especially the energy source of the brain is only ketone body except glucose. Especially in patients with type 1 diabetes, if insulin is not used moderately, ketoacidosis will occur, which is a physiological and metabolic problem and may even be life-threatening. ?

Ketogenic diet can not get enough essential nutrients, such as vitamins, minerals, fiber, antioxidants and phytochemicals. Especially people with heart disease or diabetes should pay special attention, and it is best not to try it easily. At the same time of decomposing fat, the muscles of limbs will be decomposed and consumed, and eventually muscle atrophy will occur. For example, diabetic patients with poor control will have ketosis, and the muscles of limbs will be significantly reduced. ?

Ketogenic diet can also lead to metabolic acidosis in the body, that is, the acidity of body fluids and tissues (pH less than 7.0). In addition to high-fat and low-carbohydrate diets, patients with renal failure, obesity, dehydration, excessive use of aspirin, methanol and diabetes also develop metabolic acidosis. When the body is acidic, it will inhibit the formation of osteoblasts in bones, increase osteoclasts and increase bone loss.
