It's better for a college student like you to lose weight, so you should take some time to exercise every day, mainly strength training, such as parallel bars and horizontal bars. Now that you are studying in a university, there are basically gyms in the university. Where can you go to exercise? Exercise for 45 minutes at most, and then go running or brisk walking after exercise. What lasts more than 30 minutes is exercise, followed by diet. Diet needs to eat more high-protein food, not any food containing fat, and eat less staple food. Generally eat some staple foods before exercise. Long-term persistence will soon have obvious effects.
