Say you're of an average weight, not really fat, just skinny and want to put on pounds. People who want to add muscle but are not yet serious bodybuilders(if that's even their goal)are advised to consume 1 gram per lb of body weight to bulk. Bodybuilders are typically advised 1.5-2g/lb.
Now, even overweight people who are trying to lose fat weight are also told the same thing:1g/lb.
But one thing that always intrigues me when I see it(StrongLifts report comes to mind)is when someone claims that consuming excess protein isn't necessary.
One common argument that comes from that stance is that people way back in the olden days(think 1100-1800s) didn't need 1g/lb of protein to put on mass or to get cut. Hell, who even knows if they knew anything about cutting or bulking. Most men were just naturally lean, probably from daily physical labor that was just apart of living back then, and probably due to a lot of natural and unprocessed foods(well, this could still be another question of credibility but it's not the purpose of this post).
And then the assertion is followed up with some drivel about how the ratios are just propagated through things like marketing and broscience to increase the volume of sales of whey and other protein powders. The skeptic in me wants to be like "Yeah, that does make sense actually, these industries are huge cash cows, etc., etc.", but, I'd rather have an informed opinion.
So I'm wondering, if you want to add on lean weight or lose fat weight is there really any credible research or studies showing that consuming 1gb of protein per pound of body weight has any significant impact on trying to reach your goals?
And how much protein should an individual who is resistance training for fat loss consume per lb of body weight?
Bodybuilders are typically advised 1.5-2g/lbWeird, I've always heard
