1, fat may be the word we have seen most often to describe obesity, but it is not polite to use it to say that a person is fat. So avoid using it. But we can use overweight instead. For example, my father is overweight. He decided to do more exercise to lose weight. My father is very fat. He decided to do more exercise to lose weight.

2, say a person tubby, this person is usually shorter, fatter, and may have a bigger stomach. Such people are also common, right? This 12-year-old boy grew up without exercising. The twelve-year-old boy is getting fatter and fatter because of lack of exercise.

3, short and fat, obviously, people of this size can't be described as thin? Usually, boys or girls who are good at sports in your class have such a figure. My brother does exercise every day. He is fat and healthy. My brother exercises every day. He is very strong and healthy.
