You can say what you want but for me, following D’Adamo’s eating guidelines produce the expected results; my body feels great, not sluggish, full, weighted down and I lose weight. Not sure what he’s tapped into but .. it works. According to his sales, I suspect it does for others as well. One thing is for sure, the majority of the populace will quickly abandon something that does not and I just don’t see that to be the case with this.

Anyway.. didn’t someone once say .. a man with an experience beats the one with an argument.

I suggest you give this a try, you might be pleasantly surprised.

Editor’s comments: Sigh. We give up. Really, who can argue with statements like “who’s to say your facts are any more reputable than Dr.D’Adamo’s?”

The point, Lee – had you actually READ the review you would have undoubtedly noticed this – is that D’Adamo doesn’t have any evidence upon which to base his theory. No published studies of any sort. Nothing even remotely resembling “facts.” Nien. Nyet. Nada. That’s precisely the argument. And we’re not the only ones who think so – READ the review, and see.

Additionally – again had you READ the review you would have noticed this – there are numerous reasons why the diet will work, but absolutely none of them have anything to do with your blood type. It’s largely because you’ve become selective about your food choices and are eating a largely whole foods diet.

The fact that the diet worked for you is not evidence that the “bood type theory of dieting” works (see above). And, remember… personal commentary is always anecdotal, and there’s always that pesky “placebo effect.”

Instead of accusing us of slander, why not do something useful; like post some links to the published clinical data or some credible scientific evidence that validate D’Adamo’s theories. Maybe, in the course of your research, you’ll discover the real purpose of this web site.

I lost 80 lbs in 2 years. I had to keep it gradual and slow, but it worked. I have been at my ideal weight of 155lbs for 6 years now. I feel better than I did before going on the diet and the energy, the way of thinking, etc has changed my life for the better. My grandmother who is type A, went on this diet and well, she had diabetes before and has been on it for 4 years now. She has pretty much cured her diabetes and is no longer taking any of her high blood pressure, diabetes, and cholesterol meds. Shame on you!

Editor’s comments: Aaron, I can see you spent a LOT of time reading the review. If you did, you’ll see that it’s not just us who disagrees with D’Adamo theories, but plenty of “doctors” as well. Fact is, your positive experience is not a validation of D’Adamo theories – there are numerous reasons why his diet may have worked for you – all having nothing to do with your blood type. Like it or not, D’Adamo cannot present any credible evidence to support his “eat right for your blood type” theories.

Regarding your “doctor” comment. Wow. I already addressed this in the article, but you were obviously too busy preparing to share your opinion, rather than actually reviewing our article to see what the basis for our conclusions were. Here’s what I said about being a doctor…

“No, I am NOT a medical doctor, and neither, as a matter of fact, is D’Adamo. Secondly, using the prefix “Dr.” in front of your name does not allow you to make broad, sweeping generalizations, present statements that contradict established theories and practices and promote your own theories without providing one iota of supporting evidence. The onus is on D’Adamo to prove his theory is valid. I have simply pointed out the obvious: none of his theories have any supporting evidence, and there are plenty of credible qualified professionals who contest his conclusions.”

One of the biggest complaints I have with the book is sample diet section. He only offers three days worth of sample diets for each blood type and the recipes don’t include foods from the AVOID list.

Keep in mind that he tells us to think of the foods on the AVOID category as “a food that acts like a poison.” I find it more than a little disconcerting that he can’t provide three days worth of menus for my blood type that don’t include food from a list that will be treated as a poison in my system.

In the recipe section, he acknowledges that occasionally there are ingredients in the recipes that appear on the avoid list but “you may be able to tolerate it, depending on your condition and whether you are strictly adhering to the diet.” I had planned to strictly adhere to the diet until I read that.

If it’s optional, then what am I doing? Why am I denying myself Lox when I’m allowed salmon? I think the book is a sham and I’m going to keep looking for something where at least the author takes himself seriously.

Thanks for your thoughtful review.

So, I began the blood type diet with suspicion and mainly focused on not eating the “better avoid” foods, especially dairy (milk, yogurt and occasional cheese, I stopped eating these), grains except for rice, and potatoes except sweet potatoes, and I switched to drinking more green tea than black. I did not increase my exercise, even though I was exercising at more normal levels instead of the heavy amounts I had in the past. I just don’t have time. So, I was surprised and gratified to find that after a month I started to lose weight for the first time in years and I felt better.

So, I do not know about the science and I certainly am skeptical about the genetic ancestors explanation, but I am persuaded that the metabolic factors related to one’s genetic make-up including blood type may mean that what is very healthy for some people to eat – complex grains or dairy or whatever – are not necessarily the same for everyone. (In fact, I started this after gaining 8 pounds eating lentil soup!) I was also pleased to find that many of the “better avoid” veggies and fruits for my blood type O were foods I did not much care for but had forced myself to eat because they were “healthy” (cucmber, melon,cabbage, yogurt, for example), and I found reasons why I dislike certain foods and drinks that everyone else seems to like…such as coffee or beer.

So, perhaps you are skeptical of the science and perhaps D’Adamo pushes his theories too far. But, this is the first thing that has ever worked for me. By the way, following the avoid and prefer recommendations does not mean eating an unbalanced diet. I still eat as much veggies and fruits as meats and fish, but I changed and limit my starch (as well as some of the fruits and veggies) and get the carbs from the fruits and veggies I eat.

And even when the temptation for the fried chicken came back a week later and I gave in to it I still kept losing weight to the point where I started to panic. And I have tried lots of things to lose it. So don’t knock it if you haven’t tried it. My blood type like most of us in the Caribbean is O.

Editor’s comments: Donna, I see you’ve spent a lot of time reading the review. If you want to check the last couple of paragraphs, you’ll see that I explain exactly why the diet WILL work for type O’s, and it has exactly zero to do with your blood type. Don’t confuse cause and effect here!
