In terms of food, most of the dishes in the school canteen are oily. Avoid those dishes with heavy oil, but they are not oil-free. You can eat coarse grain steamed bread and casual Chinese food for breakfast, but don't eat too much. Try not to eat rice for dinner, and eat some coarse grains, such as corn, sweet potatoes and other digestible foods.
In terms of work and rest, the most important thing is not to stay up late and develop good work and rest habits. As a college student, this thing is the easiest to do. What I can't do can only be said that my self-control ability is not enough.
In sports, run five kilometers every night or morning. If you can't run, make up. One day you will break through.
Sticking to a month will have obvious effects, but if it is a short-term effect, it must not stop, otherwise it will not be worth the loss if you miss the novice welfare period.
You can go to the gym if you can, because there are coaches there. As long as you listen to the coach more, you will definitely lose weight. I'm afraid you are a person who will never go again after three minutes of exercise, so it's meaningless to apply for a card in the gym.
Finally, I wish you success in losing weight. You have to understand that a self-disciplined person is very terrible.
