Query: I found the writing style insultingly condesceding

If you can plow through the disgustingly cutesy-poo writing style and boring background, you'll find that Keene (who is a psychiatrist, NOT an MD) has two actual statements: Prozac is the best treatment for stubborn food addiction, and before resorting to Prozac, you should subject yourself to his extremely restrictive diet plan and never eat foods containing flour or any other processed ingredients again for the rest of your life. (Personally, I'd rather be fat than go without cookies for the rest of my life.) The book does seem well researched, but I only recommend it for those planning to strictly adhere to the diet plan -- and even then, you should skip to the relevant chapter and avoid as much of the text as possible. Someone hire this guy a ghostwriter!
