For students, breakfast should be rich in protein, and the fat in three meals can reach the highest.
Students' mental activities are actually very energy-consuming, and the daily exercise of day students is basically enough (2000 steps a day). So there is no need for a lot of exercise.
According to your current situation, reduce the meat on your waist: suck your abdomen when you walk, and try to suck your abdomen when you sit. Massage the stomach before going to bed, then go to sleep 50 times clockwise (excretion) and 50 times counterclockwise (consolidation). Gradually, your toxins will be discharged smoothly, your waist will be thinner, and your skin will be much better (I have practiced).
As for the girls who grow taller and taller, they have passed the best period of growing taller, but they still grow three or four centimeters. They should do more exercise, such as playing basketball, and have a bag of milk every day, preferably yogurt, not fruity (much more energy). Eat fish once a week. Eat less sugar and snacks.
