I am embarrassed to admit I always thought people focused too much on protein and it was bro science but I also never managed to get stronger despite resistance training. Then in my forties I finally started eating 150-180 g of protein a day and doing resistance training to exhaustion a couple days a week and the difference has been huge. I wish I’d done this 20 years ago.
>I'm 6'1 and 190-200lb, and I went from 130g to 80g a day of protein for the last year and have only gained more lean mass.
And everything else was held constant? Moreover the claim isn't that you need absurdly high amounts of protein to build muscle, just that it's easier to build muscle if you have higher protein intake, all things being equal.
I just don't see it. The main connection I see is with calorie intake being slightly above vs below maintenance. How does "easier" quantify? What if it's a technically true statement but you're just talking about 2%?
It's like when you hear that steaming vegetables retains more nutrients than boiling them so everyone repeats this bit of trivia, but then you find out it's talking about a 7% difference so who cares.

I do think proteinmaxing is mostly food/supp industry hype + advice for people who need to tricked into replacing donuts with something healthier. So YMMV.
But I think the training until exhaustion part of your comment is the important bit.
