The late Dr. Roy L. Walford spent much of his life’s work researching low-calorie diets, and is now recognized as a pioneer of what is widely recognized as “calorie restriction” (CR), a diet consisting of fewer calories while maintaining adequate nutrition. In The Anti-Aging Plan, his landmark book first published in 1994, Dr. Walford presents the results of his studies and clearly describes how the principles of nutrient-rich caloric limitation can be applied to everyday dieting habits.
