Lunch: You can eat vegetables, fruits, chicken, duck and fish. Because you are a student, you have to study hard in the afternoon, so you should eat some staple food for lunch.
Dinner: Give up the staple food and eat some light vegetables. Have the opportunity to exercise more after meals. If you have evening self-study or evening self-study, it is recommended to eat less staple food at night. This is better than eating when you are hungry before going to bed.
There are several sports worthy of reference:
1. Run in the same place: choose an open space of about one square meter indoors or in the corridor and run barefoot every day 15 minutes.
2. Walking: Walking for about 45 minutes after a meal will burn calories quickly. If you walk again 2-3 hours after meals, the effect will be better.
And personally, I think that if you are not too fat, it is important to keep fit and study hard first. Losing weight can wait until college or winter and summer vacation. College is very good for losing weight, and you have time and experience ~!
I hope my personal opinion is helpful to you!
