Respectfully, I think you are looking at a smaller picture than I intended with my comment.
I agree that 1g per lb maximizes *proximal* MPS.
I was referring to the other benefits that eating greater amounts than 1g/lb per day of protein will have through Mtor has aside from that day’s MPS.
Mtor actually coordinates multiple anabolic and metabolic processes,not just proximal MPS.
More Mtor means more ribosome biogenesis, which increases your capacity for MPS long term rather than your rate of MPS today.
Mtor also stimulates glycolysis and nutrient uptake, helping cells process glucose, aminos, and lipids as well. Nutrient signalling effects via Mtor also affect insulin sensitivity.
Mtor also indirectly supports mitochondrial activity and enhances the cell’s energy capacity.
These effects are not capped at the same rate that proximal MPS is capped at.
So in short, yes, I agree that proximal MPS is maximized at 1g per day, but greater amounts can lay the groundwork for greater MPS capacity long term along with a host of other indirect anabolic benefits.
Of course, proximal MPS is the most important factor by far, but those high protein coaches were on to something. That’s why I decided to research this, I couldn’t fathom how so many respected coaches could all be wrong. It was actually a lesser known coach named Kolton (coach kolton on ig) who put me onto the trail of these benefits from Mtor.
Edit: I also forgot to add that greater Mtor can enhance hypertrophy through satellite cell activation as another beneficial pathway , I thought I was forgetting something lol
