It's a bit difficult for girls to grow taller ~ and 90 kg is a bit too thin. Just set the goal at 94~95, and it's not easy to lose weight together. The most important thing to lose weight is to eat less taboos and try to supplement protein and various nutrients. These two are not the same concept ~ If you want to lose weight, quit all high-calorie foods and snacks, a high-sugar snack is even impossible. Nutritious, but high in calories, you can forget lunch. Eat half of your usual meal. Eat vegetarian nutrition for dinner. Drink more soup and eat more fruits and vegetables. The sooner you have dinner, the better. If you are hungry, you can drink a box of pure milk (no fruit) before going to bed. You should exercise at least twice a week. Don't be too tired, walk slowly, jump rope or something. Actually, shopping is super effective. The point is not to drink while shopping.
