Of course, drinking well at night is more conducive to losing weight. You don't need a lot of fatty things at night. Eat enough fruit and vegetable juice in the morning. Fruit and vegetable juice is rich in organic acids, which helps digestion, makes the upper part of the small intestine acidic and helps the absorption of calcium and phosphorus. At the same time, it contains a variety of vitamins, which can supplement vitamins and inorganic salts and regulate the acid-base balance in the body. Note when drinking: 1, between meals or half an hour before meals is the best time to drink juice. 2, freshly squeezed juice should not add sugar, otherwise it will increase calories. 3. Don't heat it. Heated fruit juice will not only make the aroma of fruit run away, but also destroy various vitamins. 4. It is not advisable to take drugs with fruit juice, otherwise the fruit acid in fruit juice will easily lead to the decomposition and dissolution of various drugs in advance, which is not conducive to the absorption of drugs in the small intestine and affect the efficacy. 5, ulcer, acute chronic gastroenteritis patients and people with poor renal function can't drink juice.
