Dietary factors related to obesity include: liking sweets, drinking drinks, and preferring fried foods, Western-style fast food, and late-night snacks. In addition, a heavy dinner and lack of exercise after dinner, eating too fast, and irregular breakfast can also easily lead to obesity. ?

Dietary intervention can be roughly divided into the following types: ?

Low-energy diet: on the basis of meeting the most basic daily energy demand, that is, 1200 kcal (1 kcal=4.18kJ) Eat as little energy as possible every day. The intake of various nutrients basically accounts for the total energy intake throughout the day: fat <30%, carbohydrates 55%, protein 25%; fiber 25g/d. In both short-term and long-term effects, low-energy diet has obvious effects on obesity intervention in children aged 6 to 12 years old. ?

Very low energy diet (VLCD): Limits daily energy intake to 600-800 kcal. Its lower energy diet has stricter control over energy intake. The diet is mainly high-quality protein, fat intake is strictly controlled, and daily vitamins, minerals, and trace elements are supplemented. VLCD can achieve more obvious effects than low-energy diets in the short term, but it is unclear whether this advantage still exists in the long term. ?

Low-fat diet: A low-fat diet refers to using carbohydrates as the main food and controlling fat intake to 18% to 40% of the total energy intake throughout the day. This dietary regimen is most common in controlling obesity in adolescents and is often used alone. A low-fat diet can cause moderate weight loss in adolescents, but the effect is not lasting and can cause an increase in lipid compounds in children and adolescents. ?

Low-carbohydrate diet: Carbohydrate intake is less than 10% to 30% of the total energy intake throughout the day, sometimes including fat intake and total energy intake, etc. Many restrictions. Low-carbohydrate diets are more effective than low-fat diets for short-term weight loss in children and adolescents. However, whether this dietary approach is safe in the long term remains to be further explored and verified. ?

High-protein, low-carbohydrate diet: Simplifies people's food choices by reducing a large group of nutrients (carbohydrates). Studies have proven that after VLCD weight loss, a high-protein diet can enable people to maintain a suitable weight well. There is a dearth of long-term research evidence on high-protein, low-carbohydrate diets. ?

There are currently many dietary intervention studies on adolescent obesity, but there is a lack of relevant data in the long term, and there is no recognized best dietary intervention plan. Different groups of people should make choices based on actual conditions. .
