Body builders look like that because they swallow a ton of protein pills and other shit that eventually take a toll in their health. I hope for your sake you're not going down that path.
Protein, etc., is not bad for you: it's just food. Eating 1/2 pound of chicken breast, and drinking a hefty protein shake are roughly equivalent in terms of nutrition. There's nothing wrong (in my opinion) with maintaining a relatively high protein diet, unless you're eating far more than 2g per pound of body weight (at which point you're going to unnecessarily tax your kidneys to break it all down).
Many bodybuilders eat around 1g of protein per pound of body weight, which isn't terribly much. People like me, for instance, eat mainly 'clean' foods: chicken breast, brown rice, green veggies, etc. I get my bloodwork done every few months, and have never had any issues.
You're correct that top level bodybuilders are taking a toll to their health, but running a casual cycle really isn't anything to write home about. Combined with a decent body fat percentage and a few hundred worth of Test-E, you too could look like him.
There is a world of difference between the lifestyles of top level mass monster Olympia bodybuilders and casual steroid users.
