When we start dieting to lose weight, our bodies will immediately enter a "famine state" and an "energy-saving state". In this state, the body will minimize metabolism to maintain the most basic needs of life. If the calorie intake is insufficient for a long time, the body will begin to break down muscles, because muscles can provide the most calories among all energy substances, and breaking down 0.5 kg of muscles can provide the body with 9 times as much energy as breaking down the same fat. And 75% of muscles are water, and the rapid decomposition of muscles will reduce the water content of the human body, so you will see a rapid weight loss. But such a rapid decline is at the expense of our fat little muscles. We are not losing weight, we are just losing weight, numbers and muscles! Instead of really reducing fat! And because of repeated dieting to lose weight, it eventually leads to low metabolism, forming an obese physique, rebounding faster and faster, and finally leading to more dieting and fatter!

Sleeve gastrectomy, also known as gastric reduction, is one of the most popular treatments for obesity in the world. It is a laparoscopic operation to remove the large curvature of the gastric sleeve and keep the stomach capacity at about 60-80ml, because it changes the stomach capacity, thus reducing the food intake and achieving the effect of losing weight.
