In hot summer, weight loss has become a key word. Many people are either losing weight or preparing to lose weight. Various weight loss methods emerge in endlessly on the Internet, attracting a large number of netizens to keep trying... But are these weight loss methods scientific? Recently, the reporter from people.com interviewed mengfanqiang, the head of the multidisciplinary joint overweight and obesity clinic of China Japan Friendship Hospital and the weight loss surgeon of gastrointestinal surgery, to talk with you about the liquid cutting weight loss method. Mengfanqiang introduced that the liquid cut-off weight loss method usually refers to eating only liquid things, such as drinking water, yogurt, coffee, even cola, milk tea and other beverages, within the specified weight loss time, generally 3-5 days, and cutting off all normal solid diets to achieve the purpose of weight loss. "Liquid cut-off diet is actually a kind of fasting diet." Mengfanqiang said that if you limit your daily calorie intake during weight loss, keep your energy intake below your energy consumption, and stick to it for a period of time, you can lose weight. But if you don't limit your calorie intake and drink it casually, you can't lose weight. Because any energy drinks, including those containing sugar and milk, may be the culprit of excessive energy intake, directly or indirectly leading to obesity. "The human body needs a variety of nutrients every day to provide energy and nutrition for the body. The method of reducing weight through fluid interruption alone cannot be fully absorbed." Mengfanqiang suggested that the scientific way to lose weight is to control daily calorie intake and consumption, develop good eating habits, maintain balanced nutrition, avoid nutrient deficiency, and cooperate with appropriate exercise to achieve the goal of losing weight on the basis of good health.
