Most really fat people have health and fitness issues. They have all been teased, etc., for years. I doubt many actually prefer to be that big. However, it is not so easy to reverse once you do get bigger. The genes that were great for tough times hardly help in America and other rich countries. Some people eat the same amount of food as others yet put on fat.
I wonder why so many dislike seeing fat people eat? When you are large you need a lot of calories to survive. Why should they have to eat in private?
Most of the guys on Getbig know how to knock others and being fat is still an insult to many. However, imagine you are really fat and are too ashamed to go to the gym, etc., because people stare and talk about you. No one can appreciate what it is like to be fat. Sure, bodybuilders seem to be able to control their bodies most of the time so they can't understand why fat people are so slack. Well, we are not the fat people so how do we know what it is like and what our bodies do? I think we can all behave better and that includes being more tolerant and respectful of everyone no matter what their bodies look like. Many of those fat people know plenty about nutrition. If you think otherwise then go and post on their forums and see how you go. They will chew you up and spit you out.
I don't find the false tits of female bodybuilders attractive one bit. Yet many guys here rave about them gals. Goodness me, we have some strange values and preferences in bodybuilding.
