effects similar to extended caloric restriction.
If the mechanism of IF or CR is a genetic self-preservation response,4 protein cycling makes
sense. There are no essential dietary carbohydrates. Simply reducing calories (or carbs) wouldn't
necessarily qualify as a biological emergency. On the other hand, even brief absences of
essential amino acids like lysine might be enough to ip the switch. The "switch" in our context
is triggering a process of cellular housekeeping called autophagy, the purpose of which is, in Dr.
Mignery's words, "to clear the cell of degraded and aggregated proteins that are not being
handled by the other recycling mechanisms of the cell." In principle, if you clear the junk out
faster than it builds up, you postpone or reverse aging.
I'm currently experimenting with both 18-hour5 and one-day protein cycling, which I believe
(and it's pure conjecture) can also increase subsequent protein synthesis during overfeeding. For
