As a student, you will continue to grow and develop, so don't deliberately lose weight, and pay due attention to eating foods rich in dietary fiber, such as kelp, fungus, laver, various fungi, Flammulina velutipes, boletus, Agrocybe aegerita and other foods with more cellulose. Appropriately increase milk and yogurt to supplement calcium, eat more vegetables and fruits to supplement vitamins, strengthen physical exercise, and increase aerobic exercise such as jogging, swimming and skipping rope. Both help to promote the body's metabolism and consume calories.
