Mild fasting, also known as "5/2 fasting method", is a new weight-loss method initiated by British medical doctors, that is, only 500-600 kilocalories of food are consumed every day for two consecutive days in a week, and food is freely eaten for the remaining five days without control.
Carbohydrate has a great influence on blood sugar, and the increase of blood sugar will lead to the increase of insulin concentration. Insulin can store fat in the body, but its functions of supplying heat, detoxifying and saving protein can not be ignored. Therefore, it is not recommended to completely ban carbohydrate intake on fasting days, and foods with low glycemic index, such as oats and brown rice, should be selected.
