Generally speaking, it is impossible to lose weight overnight. Even if you lose weight normally and lose so much at once, you will feel uncomfortable in one way or another. Therefore, we can only give you some weight loss suggestions based on our weight loss experience:

First of all, for the thighs, you can sit half against the wall, that is, sit in a chair with your back against the wall (with the wall as the back of the chair), the thighs and calves are at 90 degrees, and your hands are naturally flat on your thighs (without force). Stick to it for five minutes and do it when you have time.

Secondly, for the stomach, it is sit-ups and insist on it every day.

Third, eat less and eat more, and have a light diet. As a student, you are not advised to go on a diet, but you can eat until 7 o'clock every meal. Eat less at night and don't eat after 8 o'clock. Drink less If you don't like boiled water, have some tea (not milk tea). I don't eat dinner every day now. Not only have I lost weight, but I have no acne on my face, but students should not skip dinner.

Fourth, regular sitting posture, adequate sleep, irregular sitting posture is easy to make people fat. When I used to work overtime, the harder I worked, the fatter I got.

I'm about your height, and I lost weight when I was fattest15,20 kg. I lost15,20 kg before (not by taking medicine), but my physical strength was exhausted, and I was prone to dizziness and irregular menstruation. So I suggest you lose weight step by step, which is the healthiest.
