Does the CRON diet (Calorie Restriction with Optimal Nutrition) hold the secret to a long life? The BBC investigates and the answers are surprising.

Video Summary

The CRON diet, a diet based on low calories but high nutrition, is followed by about one hundred thousand people worldwide. Joe, a Cronie for more than ten years, undergoes a series of tests with a man who has eaten ‘normally.’ The results of the tests are staggering. While both are in their fifties, the ‘control’ individual has aged worse than normal and has a few health concerns. In contrast, Joe has aged significantly better, and is shown to have little to no risk of cardiovascular disease, diabetes, or stroke.
