First of all, I want to tell you three things:
1, try to eat less reasonable high-calorie and high-fat foods and eat more green leafy vegetables with uniform dietary fiber.
2. Make a plan for yourself. For a year, you should have a work and rest plan every day. Can't stay up late to ensure sleep. Then you can start planning your exercise. You can divide into several groups at a time and do as much as one group. What you are most afraid of is the air barrier and the inability to persist. It is possible to achieve your goal by persisting in exercise during fatigue.
All the diet pills on the market are fake. Scientific diet+reasonable diet = success.
Come on, you will succeed.
