In half a year or so, if you want to lose so much weight and still can't rebound, the best way is to exercise. In my personal experience, I lost about 15 kg in half a year, which is still very good. The first thing to ensure is that you must go to bed around 1 1 at night and get up around 8 o'clock in the morning. Sleep is the most important thing. Secondly, you must have breakfast. Some people say that breakfast must be full. In fact, all you have to do is have lunch, a little more than half of your usual meal. Eat less greasy fried meat, and eat less at night, but it is best. Eat porridge for half an hour and go to exercise. You must not drink water after 8 o'clock, and you can't drink it. It will swell up. You must ensure that you have enough exercise. You don't need to run and sweat. You can go at will, or you can go at will. Perseverance is also the most important. I hope you will succeed.
