Eat less, drink a cup of yogurt in the morning, eat half a bowl of rice and vegetables at noon and evening, and do squats at noon, and you will lose weight obviously within one month. That's for sure, but most people will lose weight in the first month of exercise, which needs to be adhered to. But you should also eat less high-calorie food, or all your efforts will be in vain.

Also, if you just skip rope all the time, it will do great harm to your knees, mainly for leg muscle training. I hope you can combine it with other fitness exercises.
