So the guy at my GNC told me taking one scoop of the whey protein powder (one serving = 20g protein) is enough, and anything more would just go to waste. But the container says to take two scoops and that's what I've always been doing up to now. Which is the way to go: one scoop or two? He also said taking it on my "off days" would just translate to fat... is that true?
Thanks brahs.
It isn't true, or at least not that simple. The concept is that if you're taking in protein, only a certain amount can be put towards muscle synthesis and the rest gets burned off. This amount can be exceeded when you get a large amount of fast digesting protein hitting your system all at once.
This is mostly bullshit. The protein is absorbed at varying rates depending on your stomach contents and what you drink the protein with, so there isn't any set number. In theory, bigger people with larger systems could put more to use as building blocks than smaller people, so 20g is a random number.
What I would do if I were you is just drink your 40g with milk instead of water and maybe not on an empty stomach, or even better next time get a protein blend of fast and slow proteins. What I wouldn't do is think that you are limiting yourself or being overtly wasteful by taking more at once. You aren't.
This is a valid argument against hydrolysed whey protein powder though. It actually hits your system so fast it does have poor utilization rates. Plus it takes bitter and costs more. Pass.
This protein limit thing I keep hearing gets used in food too which is even more annoying. A steak isn't instantly absorbed, it takes a few hours. Combined with other food even longer. There is no real upper limit, though you don't need insane amounts to grow muscle as fast as nutritionally able.
