When discussing beauty from a universal perspective, there's no specific way to define it. In regards to my own personal perspective, I believe that fat people have potential to be beautiful. This beauty, however, is based on their will to do what's right- not their looks (at least, not to a direct extent). For example, if a fat person attempts to raises money for charity by being an artist, he/she is beautiful to me, as long as he/she does a good job and everything. On the other hand, if a fat person wants to raise money by being an athlete, then it's probably obvious by his/her looks alone that he/she shouldn't be taken seriously. In such a case, the fatness of the person should not be considered beautiful until his/her body represents the health that a usual athlete needs.
