Yes, and animal studies indicate the same effect from infrequent feeding
but with little or no CR; e.g., rats allowed to eat ad libitum every
other day or once a day for a limited period of time.

An interesting question is whether ketosis accelerates aging, however.
I recall research indicating that ketosis produces substantial free
radicals.  CR need not involve ketsosis much of the time.
