First, the relative pressure of college life is relatively small. Compared with high school, college life is relatively easy. Students have few courses and more free time. The pressure on students is much less than that in high school. Besides completing the necessary courses, they can also do what they like and feel happier. In this case, their appetite will increase and their weight gain is understandable.
Second, many college students lead irregular lives. Many college students lack physical exercise in college. When you are not in class, you basically stay in the dormitory. Sometimes, they lie in bed after dinner. This way of life is not conducive to their health. In addition, staying up late is the norm for many college students. Many college students often stay up late to play mobile phones and games. This irregular lifestyle will lead to college students' obesity to some extent.
Third, the quality of life of students has gradually improved. After the students went to college, the food became better and the students ate more. The food in many university canteens is quite good. In addition, many students often go out to parties and order takeout. A good diet leads to overnutrition, and students will gain weight. When we were in college, many students around us became fat. Some students rent a house and cook by themselves, so they will eat more. Plus they don't exercise, they will gain weight. In order to keep fit and healthy, we should control our diet and do more physical exercise to make our life more regular.
