Haha I watched this a couple weeks ago.
Another really important point they make is that even among athletes, extra protein intake does not really help. Athletes only have higher protein intake because their overall caloric intake is higher. Studies show that increased protein intake is only associated with higher athletic performance when it is alongside increased intake of other nutrients (carbs). I was looking at a meta analysis a few days ago. I don’t have the link but I took this screenshot.

So a “protein shake” is not likely to help you unless you were already protein deficient, which as somebody else pointed out in this thread, is not likely for Americans who over consume meat.
Disclaimer: I am not an expert.






I’m not sure which of us misunderstood it, but my interpretation of their findings is that overall, increased protein intake was not associated with increased athletic performance. However if you look ONLY at endurance, it was actually associated with high performance, though only when alongside carbs. Maybe counterintuitive.
Their total sample size was around 300 or 400 iirc. Pretty big, but could be better.
