CRON-diet

The CRON-diet (Calorie Restriction with Optimal Nutrition) is a nutrient-rich, reduced calorie diet developed by Roy Walford, Lisa Walford, and Brian M. Delaney. The CRON-diet involves calorie restriction in the hope that the practice will improve health and retard aging, while still attempting to provide the recommended daily amounts of various nutrients. Other names include CR-diet, Longevity diet, and Anti-Aging Plan. The Walfords and Delaney, among others, founded the CR Society International to promote the CRON-diet.

Origins

The CRON-diet was developed from data Walford compiled during his participation in Biosphere 2.

Theory

Proponents of the CRON-diet believe that everyone has what they call a "set-point": a weight, specific to an individual, at which each naturally stays when they eat their usual daily diet. Proponents believe that the set-point is determined through heredity and childhood eating habits. Proponents recommend that adherents remain 10–25% under their set-point, suggesting that this is necessary for the diet to be maximally effective.
