It seems like you’re a fan of this approach, or the guy who posted the video. NBD, just sounds like you’re more than objective here.
-Yes, it’s a cyclical approach. Still sounds nuts to me to consume that much protein in a day for any reason, but when the goal is to do a “Carb load”, it’s ludicrously ridiculous.
You’re correct, it is a bad example to site. Any pro bodybuilder that eats 500g of protein a day is most likely injecting insane amounts of chemicals into their body also, so, I’m not taking ANY cues from them in that regard. And, it’s irrelevant to the point of your post and to this guy’s video. Your original question was about eating 400-600g of protein to substitute a carb load, not to mimic the diets of pro, super-roided bodybuilders.
I get that, and personally I’ve always looked for non-traditional ways to naturally continue progressing and am willing to be open minded.
Still think a “protein carb load” is really, really dumb. If the goal was to eat as much protein as possible, or experiment with 500g of protein a day for muscle gains, I would still think it’s ridiculous, but it would make more sense. For the purpose of carb loading, 500g of protein is ridiculous.
