Only diet and exercise. I went from 170 kg to 130 kg, which is how I persisted. You can't get fat in one bite, you have to lose weight slowly. I have tried to lose weight many times, taken medicine and drank weight loss coffee. I also went to the beauty salon for massage and acupuncture. In fact, it just made you eat less and cost a lot of money. The most important thing is to stick to it. No one can lose weight at once.
