This is determined by aesthetics, and what may be missing may be made up. The mainstream aesthetics thinks that women must be thin. However, some women may not be thin themselves, so when choosing a spouse, they project this aesthetic to the other half, so she will choose a thin boy. In the final analysis, this mainstream aesthetics determines that thinness is beauty.

When people look in the mirror, they will have strong psychological hints. For example, when a man looks in the mirror, he will somehow fiddle with his muscles and feel strong. But when a woman looks in the mirror, she will feel fat all over, although it is less than 100 kg. This is how women treat themselves. Therefore, under the influence of this thin aesthetic, people think that boys should also be fat.

Thin men are more energetic.

In fact, the public's aesthetic is inclined to thin boys, because thin people give people a more skinny feeling, and the lines on their resolute faces are carved like knives and axes. This feeling of tough lines is very masculine. On the contrary, those very round men seem to give people the impression that they are bloated and angular. So most girls will think that thin boys are more handsome.

Once there is too much fat on his face, his face value will be greatly reduced, and the face squeezed by fat will not be handsome, so there must be no excess fat on the handsome face.

Caused by aesthetics

I have to say that the tolerance for fat people in this era is not very high. A fat man will feel a little inferior. It is very likely that this chubby body brought him a lot of trouble and made him lose confidence. Under the influence of this aesthetic, obesity is the enemy of both men and women for life, so aesthetics requires everyone to prefer thin men.
