I was going to wait to write my review on this diet until I'd been on it for a couple of weeks, but a reviewer made an interesting observation, pointing out that all of the current 5 star reviews seem fake (it's the only non-five star review so far), and now I'm wondering if Rodale employees really have nothing better to do. But I suppose that's not the point...

I have been on this diet for 6 days so far. This book starts you out with a 4-day "cleanse." No lemon water and pepper here, folks; you actually get real food for this one. She lays out a very strict meal plan - the same breakfast every day, same snacks everyday, and so on. Also, you're supposed to drink 8 oz of lemon juice mixed into 8 glasses of water everyday. I would HIGHLY advise investing in some sort of juicer. When I bought 21 lemons at the grocery store for my first week on this diet, the cashier looked at me like she knew what I was up to... Oh, she knew.

After four days, you won't want to look at another romaine salad, cinnamon-loaded granny smith apple, or basil eggs ever again. But then you step on the scale. I'll admit that I was a bit lazy about the exercise on these 4 days, and I only started out slightly above 150 lbs to begin with (I'm 5'6", btw), but I still lost 5.2 lbs during this time. Granted, a good chunk of that was probably water weight, but it's still quite motivating. I'll be happy to update my review as I progress along on this diet.

So even as "Wary," the above referenced reviewer, pointed out, this is probably a pretty average diet as diet books go. However, I think it's kind of neat to count antioxidants and strive for a large number (30,000 a day!) as opposed to sitting around thinking about how you only have 100 calories or 1 point or whatever left for the day.

I bought this book after seeing a blurb about it in Women's Health magazine, which is published by Rodale, also the publisher of this book. As a life-long fitness and nutrition enthusiast, I was intrigued by the whole antioxidant thing. The principles of this diet are the same as other diets--lots of fruits and veggies, lean protein, whole grain carbs, and "good" fats such as nuts and olive oil. The focus on the antioxidants is just another spin on the same healthy eating approach that has been written about in countless other books and can be found in current mainstream news stories. Although new research is constantly emerging, the science behind antioxidants and what they really do for us is slippery at best--the author acknowledges this herself. What bothers me is her statement on page 9, "Although the current recommendations are that we eat between 3,000 and 5,000 ORAC points a day for optimum health, why not get all you can?" Considering the latest research concerning the adverse effects of consuming an overabundance of certain vitamins and minerals, perhaps this was an overstatement.

One pet peeve--she mentions some foods in certain chapters and then doesn't include them on the ORAC point chart. The charts are spread out through the book and I have to keep flipping around to find the ORAC points for certain foods. The chart from the website is also not consistent with the charts in the book (such as different serving sizes), which is irritating. The author mentions several times that coffee is very high in antioxidants but doesn't give the readers how many ORAC points are in a cup of coffee.

I never intended to do the cleanse nor follow her regimented eating plan; rather, my intent was to apply the principles to my eating.

After reading a review about this book in a women's magazine I thought that this would be a great book. I ended up buying it and must say that it is perfectly average and that while the information about antioxidants is interesting, the diet plan itself isn't anything you couldn't find in any other book that promotes eating whole natural foods. Also, I would be wary of the first 20 reviews on Amazon as they were all published on the exact same day (coincidentally the same day the book came out - even though some have claimed to be following the diet for a week or more), they all have the same five-star rating and none of the authors have reviewed a book other than one written by Keri Glassman. It looks to me that they might have (although I have no proof) been written by the same person under different pseudonyms.

Other than that its a decent book about healthy eating but besides the antioxidants spin (and it is a good place to get information about the positive effects certain high antioxidant foods have on your body) it doesn't provide much information that isn't already readily available.

I am on the last day of the 4 day cleanse. The book was easy to read and the diet is easy to follow so far since you have exactly the same thing for the first 4 days and its spelled out pretty clearly. I don't know how the rest of it is going to go when there's are more choices involved. I've lost 3 pounds, which is what the book says will happen in the initial cleanse period, but I'm not really impressed. Why? It's a VERY low calorie diet with lots of protein and very low carb. This is not novel.
The argument for eating more antioxidants is valid, but I can't tell if I'm losing weight because I'm eating more antioxidants (I doubt it) or because I'm eating less than 1,000 calories a day (probably).
Overall, this diet will help you lose weight and may help you change the way you look at some foods.
