How is it that my brother suddenly gained weight? He doesn't eat much. Now the weight 170cm 180kg, but the weight is different from others, so it is unclear.

How old is your brother? ...

After slapping, I usually get fat. ...

Besides, you don't eat much. Even if you are a vegetarian every day, a bottle of coke a day will make you fat.

Look at your brother's figure. It's all over, and the skeleton is like this.

However, 180 is really exaggerated, and around 140 is right.
