Query: This diet is too strict for the average dieter.

You gotta love Dr. Ian and overall this book is very well written. But the problem is the diet is very, very, VERY strict and harsh. Against my better judgement, I purchased this book as a Christmas present for my 19-year old daughter who would not stop asking for it. She is an athlete and a college honors student, and only wants to lose 20 lbs. But I truly see no way that she would be able to ever stick to the strict letter of this diet. So I feel like I am setting her up to fail and the very first diet experience of her life will be failure. Not a good thing. I do not recommend this book for the first-time dieter, but I'm sure it would be fine for a more serious dieter. You REALLY need to be a strict dieter who can live on total fruits and veggies for 9 days if you want to use this book. Good luck.
