But there is an important point to make about the name of the website: the diet Dr. Fuhrman recommends for his patients is not fat free, and is not necessarily vegetarian.
"One thing that makes my diet different from other diets is that I encourage the intake of nuts, seeds, or avocados, except for people who are overweight," explains Dr. Fuhrman. "People who eat nuts and seeds have better blood profiles, better cholesterol, more antioxidants, and other health benefits—even though they are getting more 15% or more of their calories from fat. In fact, for some athletes I recommend a diet that has 40-50% of calories from fat. Also, I don't think children should be on very low-fat diets, and I'm not a fan of different diets for children and adults because they should be encouraged to eat together. If the children need adequate fat for proper development, parents should have some too and the scientific literature supports that it is the quality and nutrient density of the fat source, not the amount of fat that is critical here."
In his various books, Dr. Fuhrman also expresses that a healthy diet can have room for occasional servings of animal products.
(Also worth examining: FatFreeVegan.com has a cursory summary of the six-week plan Dr. Fuhrman advocates in Eat To Live. It makes a lot more sense after you read the book.)
