There are some younger people that get away with bad eating habits, and I can believe that. Though I doubt that will be the case when they hit their 30's, 40's and beyond, genetics can only take you so far for a certain amount of time. Bad dietary habits can be forever and wreck you in so many ways later.
My observation has been that genetics are one things, but drugs another thing entirely...and genetics + drugs allows for a lot of room in terms of loosening the dietary reigns. Eat like a pig and stay ripped seems to be encouraged by some of the more vocal members of this fraternity (and this adolescent mindset is indeed scary based on what I've seen and heard).
Since I come from a family of four siblings (three older brothers mind you, all into working out and bodybuilding), I have had initial exposure years ago (around 2000-2008) of many would be/wanna be bb's out there, in the teenage to twenty-something age group, that tried emulating the pros both training and diet wise (stupid, I know). Most of these young guys were true bb junkies - they watched the training DVD's, went to epos and scanned the internet for hours daily, looking for lots of related information as well as entertainment.
On that, I can only tell you what I've heard spoken and seen in the gyms, as well as the antics of friends of fellow family members:
Guys training heavy all the time and eating like out of control food nymphomaniacs; bulkers who were usually drug free but sported 40'+ plus waists and claimed that they were training for power & strength. (I guess zero dietary will power means that they had to check the power lifter box instead of the bodybuilding box.)
Natties who were either seasonal bulkers with extra fat & bloat or thinner ripped guys with abs and a little muscle, similar to a soccer player. (IMO, they looked the best usually.)
Juiced to the gill guys who ate like absolute garbage (fast food, sweets, etc.) and made up for it with pharmaceuticals. More junk food and calories? More and more drugs to make up for it. And many justified it by saying that's what the pros do to look the way they look.
And other variations of the above.
I know ShadowPro is very informed, experienced and strongly opinionated on what real bb's do by following a sound diet, taking the right beneficial supplements, monitoring their macros, etc., but in all due respect I have never seen this among the male bb folks that I've come across. Maybe these guys are wanna be ass clowns, but they all seemed to not think twice about eating what they liked and feeding like remorseless eating machines. I can remember a group trip to a buffet, with three of these guys (my bf's friends), many years ago and they all consumed garbage with such gluttony that even the morbidly obese folks were appalled at the spectacle. And these guys all looked huge and ripped; you never would have guessed that they ever ate that way if hadn't seen it with your own eyes. And by their own accounts and admission they said that eat like that all the time.
That is why I am a little skeptical whenever I hear the words blessed genetics; I think that 99.99% of the time it's more like a blessed monster drug stack. I mentioned Kali Muscle before in humor, but in actuality, if you've seen any of his YouTube clips on cooking & diet for getting huge, look at the way he eats and what he promotes. It's similar to what I've seen many young people follow in their own life, who are determined to get as close to that look as possible, minus the cooking of such junk food at home.
I don't know about these guys and their respective mental state, but that sounds to me like a long term recipe for disaster, particularly with regard to their health, though that may be way back on the list of priorities for some of these guys and their present day concerns.
