Low but sufficient protein
Keeping protein modest through midlife, then raising it again in later years
The opposite bet to the high-protein camp. Certain amino acids switch on the IGF-1 and TOR growth pathways that several aging labs have tied to faster aging, so the aim is enough protein to stay well nourished and not much beyond that. The position comes with an age split: the epidemiology reverses somewhere around 65, when frailty and muscle loss start to matter more than growth signaling, and intake goes back up. Protein quality muddies the argument, since plant and animal sources can differ several fold in essential amino acids for the same gram count.

Under 65 he argues for protein that is low but sufficient and mostly from plants, pointing at the growth pathways his lab has tied to aging. Past 65 he wants it raised again, along with fish and eggs, to hold off frailty and muscle loss.
