First grade, are you living on campus? When I was in grade one, I suddenly learned a lot, and then I had a good appetite. I ate more than ten kilograms in the canteen.

But now it has come back.

It is recommended to eat milk and eggs in the morning. Milk should be pure milk, not skim, and oats should be white, not those messy smells. Because you have studied biology, you will know that protein repairs cells and provides substances needed for growth. Without nutrition, you can lose weight all your life, but you won't grow tall after these years.

You can eat more at noon, as long as you don't eat a big bowl of meat. The starch and fat contained in these things can provide you with energy all day.

You can only eat vegetables and fruits at night, as long as you are not hungry, you will be fine, but you can't help eating or you will get stomach trouble, so take vitamins.

If you are under pressure, you won't get fat easily. My final weight will be 3-4 kg less than usual, but I will eat it back during the holiday.

Remember that drinking water is also a way to lose weight, and you should exercise more.
