I dont know how its viewed in other countries, but I can say in my work place, I see overweight people are quite intelligent in many aspects. I have so much overweight people around me and all are super geniuses.

And many are really not into fitness and stuff like that and they are very happy with the way they are. I think its all in your mind. I prefer to even think about them as chubby rather than thinking them as fat or obese...
