Breakfast: Eat nutritious food, absorb it well, and don't get fat.
Lunch: You can only exercise when you are full, but remember not to eat too much.
Dinner: Just eat eight points full. If you feel hungry in the future, eat a fruit.
Give up snacks, especially potato chips and fried foods. Not much snacks are bad for health, skin and nutrition absorption. I just need to eat a little occasionally.
Exercise more, remember: don't lie down if you can sit, don't sit if you can stand, and don't stand if you can walk.
If you go to school, you can ride a bike instead of taking a bus. And don't sit in your seat after class. Go out and dance.
That's it. You're still young. Don't cut too much.
