The weight of a person will change with their own condition, and it will change with age. Generally speaking, after the age of thirty, the metabolism in the human body will slowly become relatively slow. After the metabolism slows down, the oil and fat in the body cannot be consumed at the same speed as before. In addition, the life of people after the age of thirty is basically stable. Taking into account the above reasons, after the age of thirty, weight gain will be more severe than before.
人的体重是会随着自身的状况发生改变的，人的体重会随着年纪而变化的，一般来说三十岁之后人体内新陈代谢就会慢慢的变的相对缓慢，新陈代谢缓慢以后体内的油脂等就不能像之前一样的速度消耗，再加上三十岁之后人的生活基本稳定，综合上述种种原因三十岁之后是会比之前发胖严重的。
