1. He doesn't distinguish between blood group sub-types A1 & A2 or A1B & A2B. Regions of origin and therefore (according to his own argument) micronutrient requirements and proper macronutrient ratios of these sub-types are hugely different.

2. He has done very little (if any) independent testing to prove his lectin reactions occur as described. In fact almost no testing has been done by anyone.

3. He has plagiarized the work of Laura Power, PhD, who is the real expert on this topic. She has much more knowledge, experience, and most importantly - a huge, long-term study with clear results to prove her case. The truth revealed by Power is very, very different than D'Adamo's claims.

4. He does not account for (or apparently even understand) fundamental metabolic control mechanisms. If you lose weight with his system it will be quite by accident - or dumb luck.

I have been a medical nutritionist for many years and I assure you that the failings of D'Adamo's system are glaringly obvious to a trained nutritionist. His is a blatant commercial venture to capitalize on public ignorance by presenting a plausible theory as fact.
DO NOT FALL FOR THIS NONSENSE!

Dr Peter D Adamo does not have any published information other than this book he wrote to prove his point. Some of the items are expensive and hard to find. Hardly the type of diet for most people who are hard working and not wanting to waste their money on yet another fad diet. The bottom line on living and eating healthy is moderation, exercise and making better choices in what we eat. Fruits, vegtables, lean meats,fish and whole grains. Exercise every day no excuses, walking is a great option for most. All these things in combination will help one live longer, feel better emotionally and physically and lose weight in the process. No one said change was easy, you must make up your mind to do it. Doubt my word on this? Check out Dr. Weil's web site and type in Dr. Peter D Adamo. You'll get a no nonsense response to what is in his book from someone who supports natural healthy choices and has been published many times and has members of the health profession who respect him. Sorry Dr. D Adamo, people lose weight on your diet because it is low cal not based on anything that is been documented by more than one person in the medical field. Shame on you. Save your money people. As a breast cancer survivor, I have done my research. For those who have been successful on this plan, give the credit to yourself not to this book. How many of you who gave this a positive review are still on it? Will you be on it 1 year from now? Buyer beware!


Magic   November 11, 2001

Hello. This book gives me the type of feeling I get when I watch "Street Magic" on TLC. I'm Awed. Incidentally, I am a BRUTAL reviewer. If I smell a quack or a fraud, I go for the jugular, (to save someone time and money). D'Adamo knows his stuff. Here's the lowdown: I am an O+ blood type. Recently I had serious health problems. I saw a lot of doctors and did a lot of research, and it turned out to be Candidiasis and serious food allergies. I took a test called ELISA/ACT to find out what stuff I'm allergic to. Now, when you develop food allergies and intollerances, the first things your body starts rejecting are: 1. The stuff you never should have eaten, that your body could somewhat put-up with before, when you were younger and stronger. and 2. The stuff you ate on a very regular basis during the period of increased immune response (brought on by Candida). You want to know something? About 90% of the stuff I can't tolerate is on D'Adamo's Avoid List. DAMN IT! Magic. (The other allergies are to some stuff I ate EVERY DAY, which is normal). So my particular case helps prove him right. You want to know what else? As a child I was a very finicky eater. I loved certain foods, and I hated others. Most of the ones I hated as a kid are on his Avoid List. DAMN IT! Magic again. How does he do that? Do yourself a favor and A) Get this book. B) Get a gluten intollerance test if you are an O+ (gluten is in wheat, oats, etc...). C) Get the ELISA/ACT test (very expensive, but your health is worth more than that patio furniture you want). Here's food for thought: Most Americans are O+. Wheat is a HUGE staple here. Most O+ people are intollerant to wheat to some extent (which increases as you grow older). Some people are FLAT OUT allergic to it. Some people get different levels of A.D.D. from it. Some people are AUTISTIC because of it. Get that GLUTEN intollerance test PRONTO (and you might say good-bye to the inexplicable moodyness and lethargy you get after eating).
Good luck in your search for better health!


Too much arm-waving   February 22, 2000

I bought this book from Amazon after a referral from a friend who lives by it. The biggest problem I have with it is that the author presents virtually no scientific justification or research results behind any of the claims he makes. He freely dispenses all sorts of advice (e.g. type As shouldn't eat oranges because they interfere with digestion) and then expects readers to just take his word for it. As the world's biggest skeptic, I would normally advise people to stay well clear of this one, except for one little problem: the diet does in fact appear to be working, at least in my case. I didn't modify my lifestyle, and I haven't followed the diet to the extent that the author would have liked me to. I have, however, made a concerted effort to cut down on many of the foods he warns against for people of my type (A). In the 2 months since buying the book I've dropped an astonishing 20 pounds, down from 190. I don't know how well it works for other people, and I really don't like the unscientific manner in which the information is presented, but my own results force me to begrudgingly give it 4 stars.
