There is a saying in the "weight loss industry": "If you don't lose weight in spring, you will only feel sad in summer. What are the long-term effects on the body of some people who skip staple foods in order to lose weight? Song Xiuling, a fourth level researcher at the Chronic Non communicable Disease Prevention and Control Institute of the Guangdong Provincial Center for Disease Control and Prevention, stated on the 18th that although reducing staple food intake may cause weight loss in the short term, in the long run, not eating staple food can lead to nutritional imbalance, which may induce hypoglycemia, and not eating staple food can reduce the body's metabolic rate. Once normal diet is restored, weight is prone to rebound. Simply put, a person's weight gain is when they consume more calories than they burn, and the excess calories are converted into fat in the body. To control weight, the key is to reduce calorie intake while increasing expenditure. When the calorie intake is less than the calorie expenditure, the stored fat in the body will be converted into calories, and weight can be reduced, "said Song Xiuling. In this regard, Song Xiuling starts with three meals a day, and uses the "Golden Triangle" model for breakfast, that is, high-quality protein (such as boiled eggs, sugar free milk)+compound carbon water (such as whole wheat bread, oats, millet Congee)+dietary fiber (such as boiled vegetables). The 211 meal method is implemented for lunch and dinner: 2 fists of vegetables (such as Guangdong cabbage, oilwheat, etc.), 1 palm of one thumb thick protein food (such as perch, chicken breast, beef, pork, etc.), 1 fists of staple food (such as Mantou, rice, Steamed rolls, etc.). In addition, it is generally recommended to prioritize fish and shrimp for protein intake, followed by chickens, ducks, geese, and finally cattle, sheep, and pork; Eating in the order of "vegetables meat staple food" is also beneficial for weight control; Implement the "three no's principle": do not drink sugary drinks, do not eat processed snacks, and do not eat late at night. Of course, reducing daily calorie intake varies from person to person. Generally, women's daily calorie intake is 1200-1500 kcal, and men's is 1500-1800 kcal. Each person can develop a dietary plan based on their overweight situation and record their daily diet, such as reducing their daily calorie intake by 100 kcal, gradually achieving the goal of weight control. There are various ways to lose weight, and some people even say that taking metformin can help with weight loss, while others say that taking semaglutide is a good way to lose weight. Is this suitable for everyone? Chen Hong, director of the Endocrine Metabolism Department of the Pearl River Hospital of Southern Medical University, said that the industry recognized that an effective weight loss drug or method must meet the basic requirement that 50% of overweight and obese people can lose at least 5% of their weight within three months. According to current clinical research data, metformin does not meet this basic requirement, so it cannot become a weight loss drug. And semaglutide, as well as the recently launched teriparatide, can effectively reduce weight by more than 15% to 20%, and have been approved by drug regulatory authorities in Europe, America, and China as weight loss drugs. Chen Hong reminds that there are only five types of weight loss drugs approved by the national drug regulatory department. In addition to orlistat, liraglutide, benazepril, semaglutide, and tilpotide are all GLP-1 prescription drugs that must be issued by formal medical institutions before they can be used legally and compliantly. Now there are many advertisements on the Internet for so-called "magic medicine for weight loss", which advocate the exaggerated effect of weight loss. But most of these products have unknown ingredients, have not been approved by the national drug regulatory authorities, and lack efficacy and safety guarantees. Chen Hong said that the so-called "three poisons of medicine" have their own indications, contraindications, and side effects, and cannot be applied to all obese people. All weight loss methods, including medication, face the dilemma of rebound, which is determined by the nature of chronic obesity. All medication, surgery, and other treatment methods must be based on lifestyle interventions to produce good results. (New Society)
