Does it really matter at the end of the day? If you dont like to look at fat folks then dont look, or better yet shed yourself of silly prejudices. Is it unhealthy? Probably, but I think its just as likely to die from a car wreck as it is from obesity. I'm not fat but given the choice, I'd rather enjoy my life. The only reason I see for diet & exercise is if your weight bothers YOU and not because anyone else gives you their reasons. I personally am way more concerned with the other end of the spectrum, problems with anorexia & bulimia.
