From some things I've read about CR it sounds very much as if the benefits may come from reducing blood glucose and insulin levels. Well, we've got that nailed.

The bit about the mice living longer if they ate every other day, even if they stuffed themselves on those days, is intriguing. Dr (Mrs) Heller of 'Carbohydrate Addicts' fame originally lost a great deal of weight by eating only one meal per day, and she ate whatever and however much she desired. Hmmmm.
