Farting does not reduce weight, it is a sign of intestinal peristalsis, which is a normal physiological phenomenon. Farts are waste gases emitted by the body, the main components of which are carbon dioxide, hydrogen, and methane. When we eat, the food will be fermented by the normal flora of the stomach to produce gas. And these gases will move towards the anus with the peristalsis of the gastrointestinal tract and be discharged from the body by the action of the anal sphincter. Normal people will fart 5 to 10 times a day, too much or too little are abnormal phenomena, to be vigilant, is to go to the hospital in a timely manner to identify the cause of the disease. In short, farting is the normal performance of intestinal operation, and can not play a weight loss effect. As for weight loss, it is recommended that we still need to “keep your mouth shut and keep your legs open”.
