The annual winter break is coming, and primary and secondary school students have ushered in another happy holiday. The holiday, from the intense and heavy study to free up, children inevitably sleep a lazy; New Year’s Day, following the adults to visit friends and relatives, children inevitably big fish and meat, Sprite Coke to eat and drink a few meals. In this way, the winter break once the child will grow on several pounds of meat, the school will increase a few small fat pier, small fat girl. And, because children are less active, life is not regular, in the body becomes fat at the same time, but not see the growth of the size. If you eat something that promotes sexual development, it will speed up epiphyseal closure, which will make the child grow even taller! What to do? How to let children in the winter holidays can be happy to eat well, play well, rest well, but also can not gain weight, not premature maturity, more tall? Here I suggest that parents and children to keep a good few off: First, the good diet off. Children in the growth and development stage, and the New Year’s holiday, do not eat or drink is not doable. The key is what to eat? According to the law of nutrient metabolism, we eat in the sugar (carbohydrates) and fat is stored in the body into fat, while protein, vitamins, dietary fiber, minerals will not become fat. Therefore, if you want to avoid obesity or weight loss, you must eat less rice, pasta and other starchy food, especially to strictly control sweets (drinks, etc.), fried food, fatty meat, cream, peanuts and walnuts and other high-oily nuts. To eat more beef lean meat and other low-fat, high-protein foods, green vegetables, bamboo shoots and other high-fiber foods. Especially to remind everyone is now on the market supply of many artificial aquaculture and feed animal food contain will promote sexual development of food additives, should be limited use. For some children who have been obese can not rely on their own control diet to lose weight, my school hospital and ZJU Noether Nutrition Intervention Center cooperation to carry out a staple meal replacement as the main means of intervention for weight loss program, small fat pier small fat girls may wish to use the winter break to try. The second is to keep the activity off. In addition to controlling the diet, strengthen the movement for weight control and promote height is also very important. The children are relatively free during the winter holidays, do not let the children all day long is not to sleep or play video games. Children who indulge in playing games are too inactive and nervous, which will not only increase the accumulation of body fat, but also inhibit the growth of bones and secretion of growth hormone, leading to obesity and lack of growth. Children should be allowed to use the winter break to participate in more basketball, jump rope, jump up and touch high (that is, draw a line on the wall or hang a ball or other objects in a high place, so that children jump up and touch) and other “vertical activities”. Such exercise, not only will consume excess energy in the body, but also stimulate the development of bones, thus playing a role in weight loss and height. The third is to keep a good sleep off. In the winter holidays if children are not active all day and night, eating and sleeping, sleeping and eating, will certainly bring about an increase in weight and body fat, not good for a month into a small fat pier or a small fat girl. But if you stay up late every night watching TV and playing games, it will lead to insufficient secretion of growth hormone in the body, slowing down bone growth, which is not conducive to children’s growth. Because the peak of human growth hormone secretion is about 10 pm to 7 am during the sleep process, it is recommended that children must maintain a regular life, go to bed before 10 pm and get up before 8 am every day. Before going to bed and after waking up to do some of the “vertical movement” mentioned above, will certainly promote physical growth. Maybe once the winter break is over, you can grow 1~2cm! Fourthly, it is important to make sure that you visit the doctor. About 10-15% of obese and short children have some disease factors, such as growth hormone deficiency, vitamin D deficiency, micronutrient deficiency, precocious puberty, etc. Overweight children also have hypertension, hyperglycemia, hyperinsulinemia, abnormal lipid metabolism, etc. Therefore, parents are advised to take their children to the hospital for necessary checkups during the winter holidays when they are relatively free. In conclusion, weight loss, height increase and prevention of precocious puberty in children is a systematic project closely related to lifestyle. Only by starting with diet, exercise, and lifestyle patterns, and by keeping a good eye on the “mouth, legs, early sleep, and early checkups,” can we raise children with tall, healthy bodies.
