Your correct. We have no argument. First, you questioned even the existence of vegan bodybuilders, then whether they compete, now the level of competition and if they weigh more than 130 pounds. OK, yeah really solid reasoning.... Keep consuming animal products since clearly all those guys are puny and weak.
lol who proposed the argument regarding vegan bodybuilders? Here's a hint... it wasn't me. They are the exception, not the rule.
Competitive bodybuilders who have never juiced are probably rarer than unicorns. I would think that the source of protein argument is moot, relatively speaking, in comparison to the juice/no-juice question.
The real question might be do vegans live longer and have better health outcomes compared to occasional meat/fish eaters? What happens when the vegan does not supplement B12 and O'3? Does the occasional meat/fish meal "kill" prematurely or enhance nutritional quality?
I remember listening to a science radio show some months ago about a study that was conducted over a 20- or 25-year period among older Japanese respondents/participants. If I recall correctly (don't quote me on this), the study was divided into 3 groups: those who ate only a vegetarian diet; those who focused on a vegetarian diet, but supplemented it with modest amounts of meat (say twice a week); and those who consumed a fair amount of meat in their diet. Again, based on my recollection, the group that fared the best was the group that consumed a modest amount of meat along with a largely vegetarian diet. They had better overall health and mobility than the veggie-only group. The group that fared the worst was the high meat consumption group for the obvious reasons. I have not looked it up, but I think it was referred to as the Okinawa diet or study.
Atticus knows his stuff with bodybuilding/fitness/health and options trading. I'd suggest listening to him on these topics. I'm a former competitive bodybuilder, and yes, I do eat meat. I like buffalo, and venison for red meats, but mainly consume fish, egg whites, and skinless chicken. (legumes too) ZERO deepfried stuff, or ribeye steaks, etc., (Yes, a ribeye steak does taste good when prepped well though. Just high in saturated fat...) As for the vegans, I know a guy in California who eats zero meat, zero dairy, etc., He's a total extremist. He and I often get into yelling matches over his getting on me for eating some fish with my brown rice, and broccoli. The guy runs 80 miles at a time starting in the desert at night, and ending in San Diego by morning. His LDL (bad cholesterol) is 47, and his HDL (good cholesterol-high density lipids) is usually around 59. Mine isn't as good, but I don't run 80 miles either. Lol! He claims all of his good blood panel proflies are due to the diet, but I believe it also has to do with the cardio he does. Bottom line imo, if you want to be BIG, you will want to at least consider egg proteins, fish, skinless chicken, low fat cottage cheese, and legumes of different types. If you want to have the "six pack look," but be very lean (looking almost skinny with clothes on), a vegan diet 'could' work as long as you have pretty good genetics. I know ZERO top-level bodybuilders who are vegan. Bodybuilding is imo 70% about the food, the other 30% is about proper REST/RECOVERY, how you lift what you're lifting (i.e., proper form over massive weight and sloppiness), and supplementation. I eat eight small meals per day, and bodyfat is 11.4% right now. When I want to get contest prepped at around 3.5-4% bodyfat, all I need to do is increase cardio, lower the "fast" carbs, slowly stepping down calories, and INCREASE protein intake at the same time. I may drop down to around 8% over the next month, but I'm not stepping on stage. 3-4% bodyfat is TOUGH to maintain without running around town with the sniffles from a cold, or aching from the LOW bodyfat. The paper thin skin look is cool, but it isn't meant to be maintained all year. At least I can't imagine doing it! at 5% and less, I start to ache a little, and if I don't wash my hands OFTEN, I will catch a cold in the middle of the Summer, no question. (I've not had the time to read the entire thread. I hope this post isn't too far off topic.)
