First, do more exercise. You can do sports on the university playground, such as running, yoga, basketball and so on. Or you can take part in sports organized by school or physical education class, or you can go to the gym to exercise. Gyms are also very popular now. I believe there will be many gyms near the school. You can choose one of them and have more professional training there.
Second, go to bed early and don't stay up late. Nowadays, college students seem to be used to staying up late, going to bed almost after one o'clock and getting up early for class in the morning. This kind of lack of sleep is particularly prone to obesity. If your roommate will affect your sleep time or quality, it is recommended to communicate with your roommate and express your thoughts or needs in a peaceful tone. I believe your roommate will understand you. Earplugs and eye patches are also very good choices. Wearing earplugs and eye patches can keep you as quiet as possible, and collective life needs to adapt to the environment.
Third, choose the meals in the canteen reasonably. Eat breakfast, eat less fried food, eggs and soy milk. Eat whatever you can for lunch and dinner, regardless of cooking, but don't eat fried food, eat less greasy food, eat more fruits and vegetables, learn to choose your own ingredients and eat in moderation.
Fourth, don't eat supper. Often some students will be hungry after self-study in the evening and want to eat supper, but they want to lose weight, so don't eat supper, because supper is easy to make people fat, which will lead to a series of metabolic problems, such as hypertension, hyperlipidemia and high uric acid. It may even lead to diabetes. Nightingale can also lead to gastrointestinal diseases, thus affecting sleep and indirectly making you fat.
The above are my suggestions on how to lose weight during college. The important thing is whether I can implement them myself. Losing weight is an act. If you can't carry out the behavior, you can't get good results.
