Are Paleo and ketone diets effective because of their effect on mitochondria?

To explain the phenomenon, Ames came up with a theory rooted in our hunter-gatherer past, when micronutrient shortages must have been recurrent: To make sure the species was perpetuated, natural selection imposed a “strategic rationing response,” shunting the vital nutrients toward functions essential for short-term survival and reproduction, and away from longevity systems affected by dysfunctional mitochondria.

Personal theory of mine. Lots of overlap to be a coincidence. Plus the umami hit of high-protein foods, broken down by aging and roasting.
