Assuming the human body is no more than 20% amino acids by weight a person weighing 100K would only be 20K amino acids.
How much of these amino acids is it reasonable to assume we would need to replace each day? less than 1%? For a 100k individual that would be 200g of amino acids which would translate to about 1k of body weight after water and mineral content is removed with it.
How much can we reasonably expect to add to new protein synthesis each day with each additional unit of amino acid we add to our diet? Could we reasonable expect to add 1% per day? Not likely.

I eat much less than 200g of protein per day (often less than 100g/day) and am about 100k (probably closer to 89 kg fat free) and am still gaining lean mass.[/quote]
that’s good if you are gaining lean mass but it does not mean it is necessarily optimal.
Layne Norton with a PhD is protein Metabolism reccommends 20-40g of protein 4-5 times a day to maximize protein synthesis.
I remember he also said once that 40g didn’t offer a huge benefit over 20g in a single dose but still did say it did improve protein synthesis some and I know most of us who want to be as big as we possibly can do care to have an extra even just a 1-5% edge.
Now I’m not reccomending insane amounts of protein but to me a diet of 200-250g of protein isn’t harmful and doesn’t promote fat gain. So in my opinion there is no real reason to reccomend 100g vs 200g
