What It Is

What Color Is Your Diet? is a diet for health, especially cancer prevention. It's not specifically a weight-loss diet. But as it warns against sugars and fats, promotes exercise, and encourages sensible portions of healthy foods, a person following the diet would eventually lose excess weight.

What Color Is Your Diet? author David Heber, MD, PhD, is no lightweight in terms of academic credentials. He's the founding director of the UCLA Center for Human Nutrition.
