1, the key is persistence, and persistence is useless.

2, aerobic exercise will be effective, such as jogging, jogging, aerobic and so on. Every exercise is not an interval of 30-60 minutes.

3, don't pursue too fast, otherwise the body can't eat, it is easy to give up, and only once you give up, your weight will rebound immediately. It is enough to lose 3-5 kilograms every month.

4. Eat reasonably, don't be overnourished, and don't go on a diet to lose weight.

As for how long it will take to see the difference from before, I think I can see it by losing 5 kilograms.

I wish you health and success in losing weight!
