英语翻译如今肥胖症越来越常见了,尤其是在年轻人当中.引起肥胖的一般分为外因和内因.内因一般是指个人遗传因素,神经精神因素

Obesity is now becoming more and more common,especially among the young people.The causes of obesity are generally attributed to two kinds of factors:internal and external.The internal factors of obesity generally include individual genes,neurological disorders,mentalities,hyperinsulinemia,brown adipose tissue abnormalities,and various other factors.
The external factors,however,are the main causes of obesity,with the major factor being eating excessive food without sufficient exercises.Increased fat synthesis as a result of caloric intake more than calorie consumption is the material basis of obesity.Therefore,developing good living and eating habits by not eating excessive sugar,carbohydrates,and foods with high-fat or high-calorie content,while also participating in a variety of exercises or physical activities,is important to fighting obesity.
As we pay attention to the external factors of obesity,the internal factors of obesity can not be ignored either.Therefore,we should also do preventive work for the internal factors.During the later stage of fetal development,the number and volume of body fat cells increase at the fastest rate in the baby's lifetime.For this reason,during later stage of pregnancy,pregnant women should pay attention to nutritional intake,in order to avoid excessive nutrients flowing into the baby's body for the formation of fat cells.
During infancy,babies should be breastfed according actual needs.Studies have shown that prevalence of obesity for babies fed with milk is significantly higher than breastfeeding.Also,after the baby is born,the baby should not be fed solid food within three months.If the baby is already obese four months after birth,care should be taken to avoid further excessive intake of calories.During the time from six to eight months after birth,obese children should especially minimize the amount of milk intake by replacing milk with fruits and vegetables,while also using whole rice flour instead of white-rice-refined products.
