In the past two years, the concept of fasting has been made to be very popular. Many new terms have emerged such as light fasting, intermittent fasting and so on. Some studies say that intermittent fasting can stimulate metabolic shifts, help lower blood pressure, blood lipid levels, etc. It can also help reduce the risk of obesity and diabetes, and benefit brain health. However, some people say that intermittent fasting needs more research and is not suitable for everyone, so it should not be tried blindly. First, let’s look at how intermittent fasting works. Intermittent fasting means eating at some continuous time of the day and not eating or consuming calories at other times. The 8-hour diet, which has been hot for a while, is actually similar to the same thing, and is essentially a diet. This disguised dieting method allows you to reduce weight for a short period of time, but after resuming a normal diet weight immediately rebounded, and may even intensify. Obviously, the few pounds lost is not meat, but the result of water and food evacuation. If you try often there may be adverse reactions: constipation, overeating, stomach pain, metabolic capacity is reduced, the loss is not worth the gain. In fact, we all know that fat is mostly due to poor lifestyle habits. Unless the bad habits are completely corrected, there is still a risk of regaining weight. We cannot include any weight loss method that requires willpower to maintain in our weight loss program because it is difficult for us to stick to it for a lifetime. Therefore, bariatric surgery is a scientific solution to obesity. Bariatric surgery is not a big open surgery as many patients imagine, but a fine operation using minimally invasive laparoscopic technology to magnify the surgical picture four times. And only three to five small one-centimeter holes in the belly, through the operation of professional extension instruments can complete the entire operation. A skilled surgeon can control the operation time to about 100 minutes, with less than 30ml of bleeding, and the operation risk is lower than laparoscopic appendectomy and cholecystectomy in a mature weight loss metabolic surgery center.
