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. In the latter half of the book, Dr. Walford and his daughter Lisa, a chef and yoga instructor, offer over one hundred delicious recipe ideas that apply to Dr. Walford's diet plan.
