It's ridiculously easy to get your recommended daily averages even as a vegetarian without thinking about it. Rice and beans? Complete amino acid profile. Same with bread and butter. But let's get into statistics and leave the anecdata behind us! Most Americans are consuming double their recommended protein intake, but half the fiber: https://www.deseret.com/2024/1/30/24055585/americans-eating-...
Aside from that, there is plenty of evidence that the RDA is woefully insufficient, e.g.:
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9963165/
https://pubmed.ncbi.nlm.nih.gov/26960445/
That second article says in its summary: "Current evidence indicates intakes in the range of at least 1.2 to 1.6 g/(kg·day) of high-quality protein is a more ideal target for achieving optimal health outcomes in adults". That's slightly lower than Examine's figure of 1.2 to 1.6, but whatever. Even assuming the lower figure of 1.2, 56g would be sufficient for a 46.7kg man. I don't know many of them.
That's just after a 30 second search. I can't find the study right now, but if you lock people in a metabolic ward and only give them the RDA of protein, they lose muscle mass. It's not even sufficient for maintenance.
I'm not a bodybuilder, and I'm not "cutting", I'm just losing some weight and want to make sure that what I lose is fat, not muscle. Again, maintaining muscle is about much more than bodybuilding, maintaining basic strength is essential to living a pain- and restriction-free life. I'm more systematic than most because I know that makes it more effective, but wanting to lose weight is not a niche use case. I'm also trying to get my parents to eat more protein because they're older and there's plenty of evidence that their needs are higher, and it's very difficult for them as vegetarians (partly because they resist lifestyle change, admittedly).
