A calorie diet of less than 800 calories per day belongs to a "very low calorie diet" in medicine, which will lead to a decrease in thyroid hormone secretion and a long-term slowdown in metabolic rate. You may faint and your heart beat faster because you eat too few calories. Worst of all, the percentage of fat lost is very low. When you resume dieting, your brain will send instructions to your body to store more fat in case of your "catastrophic fasting".

This method of losing weight with life is unnecessary. Going out for a walk every day is hundreds of calories. With one-sided hope, following the method of drinking some supplements to lose weight is not suitable for everyone.
