These are all mixed up. 5 isn't fat, 5 is chubby and curvy.
6 is fat, but also obese.
3 is more boyish.
0,1 and 2 are emaciated.
Where did the pic come from and who did the labelling. If women did the labelling, then it's understandable, as women
want to denigrate women who are built better than they are or are harsher on body types...
Curvy and athletic/normal are the best. If curvy gets pregnant, it's downhill from there. If athletic or normal get pregnant, they either keep the same figure or get curvy (or in the US the normal chick gets "comfortable" and gains a ton of weight).
