You're just another dude who can't think for himself. Are you saying that bodyfat is lost via water manipulation? Be specific or be quiet.
I'm going to educate you quickly while I eat my lunch here at work. When gh15 refers to bodybuilders, he is talking about horminzed bodybuilders, not naturals, and when it comes to bodybuilding there is no such thing as natural. Yes, sure, they exist and enjoy being 180 lbs 6%, but that's not what is being talked about. Bodybuilders who will actually be remembered, like Arnold or Serge Nubret, or Jay Cutler. 50 years from now, in the bodybuilding cult, those guys will still be mentioned. Liars like Layne Norton will be remembered as "that guy" who was good looking for a "natural" (""'s because we know he isn't).
Now with bodybuilders, they hold little to no fat due to all the hormones they are on. Even when you see guys "fat" in the offseason, they are not fat. They are just water logged from long esthers and HGH and no diuretics or ephedrine. Top pros doing guest posings are a good example of this look. When gh15 is calling out guys bf %'s he is talking about strictly FAT. They look fat because of all the water bloating them or that is sitting between the muscle and skin, BUT very little of it is actual FAT. Understanding the difference in the look is where it gets tricky. For naturals, real naturals, they eat very clean and do lots of cardio so they have little to no fat, BUT they are not on diuretics or anything to help them cut water so their body's natural water retention remains and also the additional water retention from the creatine and whey protein powders and all other supplements that naturals use that cause water retention, again, as has been said before, it blurrs lines, cuts, and abs, and then becomes mistooken for fat. People here get frustrated because they don't understand and have a difficulty seeing the difference. Have one of these naturals with a bf% that you disagree with gh15's call on pop a diuretic. A REAL DIURETIC. Dyazide, lasix, aldactone, etc... and WATCH... all of sudden you'll be like "oh wow now he does look like what gh15 said" and it won't be because they all of a sudden lost 5-10 lbs of fat lol, it'll be because the water is gone! With bodybuilders (the real ones now), those lbs of water can be 20-30!
Don't get frustrated because you don't see it. Take some time and look at off season photos of guys. Look at contest shape guys. Look at naturals the same way. Look at people who are actually 15-20% bf. Take the time to do these things and you will see the difference and appreciate more what is being talked about.
Remember, nowhere in any of those claims of bf% did gh15 claim that a guy had a really good physique. He just stated what % of their body was ACTUAL FAT and he wants you to understand (he's helping you be a better bodybuilder really) that WATER on the body and FAT on the body are two different things and look totally different.
