Drinking 15ml vinegar before going to bed at night can reduce weight. Vinegar contains more than 20 amino acids and 16 organic acids. These amino acids and organic acids can promote the metabolism of sugar, so that sugar is consumed in the body instead of being converted into fat and stored in the body. Regular consumption of vinegar can not only consume body fat, but also promote the metabolism of sugar and protein. Protein in the body can be converted into energy to lose weight, so most female friends can drink 10- before going to bed.
