1. Low-carb diet weight loss method refers to a low-carbohydrate diet, that is, strictly limiting the intake of carbohydrates and increasing the intake of protein and fat in the diet. It was first proposed by American Atkins in "Dr. Atkins's New Diet Revolution" in 1972.

2. At present, the effect of low-carb diet is still controversial in the medical community. Supporters believe that low-carb diets can reduce body weight (about 10% on average) and blood cholesterol levels (about 5% on average) to a certain extent, and reduce the risk of heart disease, but whether it is effective in the long term is uncertain. Opponents believe that few people can adhere to a low-carb diet for a long time. Studies have found that only 1% of people can adhere to a low-carb diet for an average of 19 months. Moreover, low-carb dieters eat less carbohydrates and eat more protein and fat, which runs counter to the health concepts of the medical and nutritional circles and is not suitable for patients with coronary heart disease, gout, and kidney disease.
