First of all, if you want to keep your weight and don't want to rebound, you must keep exercising. You should keep the same amount of exercise as before, and you can't be lazy. Otherwise, your weight will definitely rebound, and your three-month efforts will be in vain.

Second, develop good eating habits, eat a balanced diet, eat less high-fat and high-calorie foods and eat more fruits and vegetables.

Third, work and rest regularly, go to bed early and get up early, and don't stay up late.

I hope my answer can help you and make you satisfied.
