Protein powders are like fast food - you can use them in a pinch but should not rely on them as a staple. This is from someone who’s spent way too much on these over the years (in my 20’s and 30’s), based on a false belief they were needed to get and remain strong. It was a simple test - stop taking them and see happens. I lost no strength, but gained some extra cash in my wallet. Plus, you definitely feel better eating real food calories and not concoctions. Let’s face it - 99% of the supplement industry is based on scams and huge mark ups. They take some cheap byproduct, put it in a fancy looking plastic container, give it a tough-sounding name and some unverified claims, and charge us $50+ for it. No thanks. I’ll stick with eggs, nuts, fruit, veggies, and meats for my money.
As for a quick on-the-go post workout? I like bananas, almonds, or beef jerky (check ingredients) and then get meal in within the next hour or so.
