Beyond the 120 Year Diet, by Roy Walford

Beyond The 120 Year Diet : How to Double Your Vital Years, published in 2000, is the follow-up to CR guru Roy Walfords's classic, The 120 Year Diet. In layperson's terms, Walford describes how and (theoretically) why CR works. Apart from being and excellent and well-referenced science book, it is a manual for human CR. Here are some of the many subjects discussed:

--Biomarkers of aging, and tests you can do on yourself.
--The concept of nutrient density.
--How to lose weight.
--Fasting.
--The nature of evidence.
--Interacting with your chosen physician.
--Prevent what is going to kill you.
--A lesson from Biosphere 2.
--The complex philosophy of supplementation.
--Exercise, stretching, and the maladies of wear and tear.
--Recipes.
--Dining out.
--Chart: Nutritive values of the best foods.

This book is frequently cited by many CR Society members and can be considered -- for now, anyway -- the "bible" for practicing human CR.
