Query: I like Marilu as an actress but . . .

Why should I believe any of this "research"? After all, Marilu is an actress, not a nutritionist or medical doctor. Her complaints against dairy products sound like a boring repeat of Susan Powter's opinion in "Food." Very few people will want to follow her extreme program, even if they could understand it. I don't know why so many people rated the book highly and then said they didn't understand the program. To me this is just another "extreme" diet that may or may not be healthy in the long run.
