DetoX and Calorie Restriction

The current calorie restriction movement appears to flow from:

1. an experiment comparing underfed rats to those allowed to eat at will
2. domed scientists forced by necessity to restrict calories for 2 years.
   
3. the Okinawan practice of Hara Hachi Bu (eating until 80% full).

The Okinawans are the longest-lived people on earth. the scientist were uncharacteristically disease-free when they emerged from the dome, and the underfed rats lived longer, healthier lives.

In the belief that calorie restriction provides support for the practices of cleansing/fasting, I am reading every book I can find on the subject
