Sleeping on your side to lose weight is called "the last chance to lose weight". The liver is in the upper right abdomen, and when lying on the right side, it is in a lower position, so blood can be supplied to the heart more, which is conducive to digesting food and metabolizing nutrients in the body, without worrying about obesity. However, sleeping on the right side and sleeping on the left side belong to the bow sleeping position, and the back can't be stretched, which will accumulate fat. But in comparison, sleeping on the right side is the most weight loss.
