Of course it's not scientific. If you are a girl, I suggest you do the most basic aerobic exercise (jogging).

It's best to run 5 kilometers a day (if you want to get good grades, it's best to run in 26 minutes and I'll run in 22 minutes)

Also, don't overeat after half an hour of exercise, you can eat 7 minutes of rice. The diet is simple. Eat more vegetables and less greasy things. You can eat meat, but you must control the amount. Don't go on a diet, or you will become faster. )

Any weight loss should be combined with exercise, otherwise it is nonsense (it takes a lot of confidence and perseverance to lose weight)

I wish you success in losing weight!
