Since the summer vacation, the daily reception volume of clinical nutrition clinics at Beijing Children's Hospital has increased by one-third. Outside the consulting room of chief physician Yan Jie, there are often many children waiting in line at 7pm, including many "little chubby people" who come to consult about weight loss issues. During the holiday at home, children like to drink drinks and eat watermelons, and feel like they have gained weight again. "13-year-old boy Wei Wei, accompanied by his mother, walked into Yan Jie's consulting room. Wei Wei is 149 centimeters tall and weighs 67 kilograms. Among children of the same age, she appears a bit short and quite overweight. My mother was worried about his growth and development issues, so she took him to the children's hospital for examination. The child has an advanced bone age and a body mass index (BIM) of 30, which belongs to the range of obesity. According to various test results, Wei Wei's blood sugar is at the critical high limit of pathological indicators, and uric acid and insulin are no longer normal. "If there is no further intervention, you will get sick." Yan Jie diagnosed that Wei Wei Wei's "body problem" is related to genetics, early growth and development, and bad lifestyle habits, and other factors. Personalization has been developed for him Comprehensive intervention plan. He only eats meat, and I can't say anything about him. "7-year-old Jiang Jiang is 130 centimeters tall and weighs 55 kilograms. Recently, Jiang Jiang's mother noticed that her child's neck was getting a bit black, so she quickly took him to the hospital. Jiang Jiang's obesity is currently not pathological, mainly due to excessive food intake leading to fat accumulation. "After reviewing Jiang Jiang's physical examination report, Yan Jie gave anxious parents a" reassuring pill ":" Now we must control weight quickly, and these indicators can return to normal. "However, she also reminded parents that after children enter puberty, hormone levels will undergo significant changes, which will make weight control more difficult, "'Little Fatty Dun' can be cured as soon as possible." "Children's obesity is mostly caused by comprehensive factors, but 'Little Fatty Dun' has bad habits such as excessive intake of high calorie food, sugary drinks, and long-term lack of exercise." Yan Jie said that childhood and adolescent obesity may lead to high blood pressure, diabetes, gout, girls' polycystic ovary syndrome and other diseases. Obese children are also more prone to abnormal secretion of sex hormones, leading to problems such as precocious puberty and short stature. At the same time, obesity may also have an impact on children's mental health, and without intervention, it can also increase the risk of obesity in adulthood. The popular online weight loss methods such as' liquid interruption 'and' ketogenesis' are not suitable for weight control in children and adolescents. Yan Jie also reminds that children and adolescents are in the process of growth and development, and weight control should also ensure that their physical and mental development is not affected. 'Xiaopangdun' should scientifically and reasonably develop a daily diet according to the requirements of the 'Chinese Dietary Guidelines for Residents', and control total calories while ensuring nutritional balance.' In terms of exercise, it is recommended to combine aerobic fat reduction with anaerobic muscle gain. 'It is recommended that children accumulate at least 60 minutes of high-intensity exercise every day, including playing ball, running, skipping rope, etc., which are good choices.'
