Do you need to ask fat people if they can lose weight through exercise? There are too many examples.

However, there are different types of people's bodies. For example, sometimes someone is said to be "small skeleton, secretly fat", but in fact this person is said to be a small skeleton. Although he has a lot of fat, it is not obvious because his overall figure is relatively small (but it is still obvious if he reaches a certain level, such as Ceng Zhiwei, a former football player). People with big skeletons are big, and they feel strong if they are fat.

I can't go on because a simple question is difficult to explain clearly. For example, if you ask a pig why it is not a dog, it is hard to say why, because it is not.
