If you are not overweight, I suggest that you still take healthy ways to lose weight, such as exercise and dieting. Sticking to it for a while, plus correcting bad eating habits, will definitely help you lose weight. However, if you are overweight or have other symptoms caused by obesity, I suggest you take the way of shrinking your stomach to lose weight. At present, there are gastric volume reduction, gastric bypass, gastric bypass, gastric contraction and laparotomy. I hope my answer can help you.
