Hello, I’ve recently gotten back into working out. I’ve been gaining more strength, but have been putting off getting enough protein and carbs, as that’s a whole other can of worms I’ll get to eventually. I understand that you build muscle very quickly as a beginner. My question is: do you “waste” newbie gains from gaining strength but not optimizing it with proper diet? Also how long do newbie gains typically last before they platue? I’m guessing that it’s extremely variable, but maybe there is a set timeline who knows.
