In the time of gathering with friends, there will always be a small amount of food around the friend. During the meal there will also be some fat friends intentionally or unintentionally glance at how much others have eaten …… Then looked at the lunchbox in his hands, fell into a deep meditation: if I exchange diet with her, then I can be as thin as her? Many people have had this idea, but is this method actually feasible? The body’s stomach capacity, digestive function and absorption function are generally different from those of normal people who are prone to fat. In fact, exchanging diets with thin people is essentially reducing food intake, which is frankly equivalent to dieting to lose weight. It is likely that the situation is that others can eat this amount of full stomach without having to continue to eat, while you eat the same amount of not only full, but also need to starve. In the long run, such a weight loss method is not only ineffective, but also harmful to your health. The reason for this result is mainly due to the above-mentioned differences in stomach capacity, digestion and absorption functions, your body decided that you need to eat so much, then, easy to fat people can only “sit and wait”? The reality is that there is a way to redirect stomach volume, digestion, and absorption for weight loss. Bariatric surgery is a minimally invasive procedure that uses laparoscopy to reduce the volume of the stomach inside the body or to reduce the absorption of nutrients by reconstructing the digestive tract.
