Your blood type can have a lot to do with the way in which your body processes, digests and metabolizes food and nutrients.

WOW - I am an A negative non secreter while my family is A positive secreter - The food they gave me was crap and I paid for it with massive eczema. Now that I am older and in control of my food intake, I feel SO MUCH BETTER. I did the swami too, which was helpful but get more from just the 'nuts and bolts' of the BTD. If you haven't figured out if you were a secreter or non secreter, you should - it made a HUGE difference in everyday foods. I have not had eczema OR constipation since. I am a happy girl. Thank You Peter D'Adamo!

Amazing, life changing and empowering!

This review doesn't scratch the surface of the flawed science of the diet. It doesn't add any information that couldn't be determined from the cover of the book.

Changed my life.

I'm an O negative and giving up grains and most dairy products really changed my life. I do a modified version of this at the moment, based more on a paleo/primal type of diet, as I'm trying to drop some pounds, but it's basically a narrower version of the blood type diet.

Not more headaches, tinnitus, bloating/gas/diarrhea, joint pain/fibromyalgia, only cure ever for my adult acne (I've tried it all). I even used to have seizures. I wouldn't so much call this a diet as I would "food as a drug" plan. Try it if you have any chronic health conditions. Seriously...you have absolutely nothing to lose!!!

I don't know if I believe the science, my only evidence is how I feel when I actually follow the recommendations. I have been on this diet three different times. Each time within four days my entire body feels different. I feel good, like my body is running on the proper fuel. Nagging issues like congestion are gone. Two relatives have also used the diet. Each one has felt better when they are on it. One has alleviated all of her digestive issues by going on the diet. So my advice is that even if you don't believe the science, most likely you will still feel better.

Just started this 3 days ago! Type O and cut mainly on wheat and more of meat! Didn't even notice anything until my husband told me I'm losing weight! Especially on the belly bulge! I'm sticking to it!

This diet has been amazing! I have been on it for nearly 5 years and lost baby weight 4 times! Since I do have four little ones, it is hard for me to stay on it very strictly but just simply by avoiding the foods on my "no no list" and trying to eat foods on my beneficial list I can tell a huge difference! I even started a blog to tell my friends and family called www.lovemybloodtype.com. Thanks for the review

I love this diet. I've been on it for a few years and it has helped me to lose weight with no effort especially when I cut out the wheat completely. Many Blood Type O's are gluten intolerant and must cut out the wheat in order to lose weight and get rid of digestive problems. I no longer have any health problems after eliminating the most damaging foods for my type: wheat, corn, kidney beans, potatoes, and peanuts. This diet works; give it a try!

@Brittany, I agree with you 100% that the blood type diet works and makes sense!!! I struggled with my weight for years and last year a friend introduce me to the whole concept of blood type dieting, I started in May of 2009 at 242lbs and by November 2009 I had lost 82lbs all from dieting according to my blood type. My success has now inspired me to help other people who are struggling to lose weight and thus created my own ebook on your blood type diet.

For years I have had problems with high acid foods. Things like pickles, orange juice, and salsa would often make me vomit. The O blood type diet suggests i cut out high acid foods because O blood types have high stomach acid already. Interesting, huh? After reviewing the diet regimen, most all of the foods that I was supposed to be eating were foods I already favored to begin with, such as leafy vegetables, seafood, and darker fruits. Many of the foods not allowed were foods i didn't really care for anyways. How weird! These blood type diets are great and make perfect sense!

Started the diet around 4 weeks ago not really thinking it would make that much of a difference but decided to give it a go after reading recently how different blood types are more susceptible to different cancers and I definitely feel better. I have stopped getting aches and the heartburn/indigestion that I have been feeling for a few years. I went off it for just one day a few days ago and ate most of the things on the avoid list ie. bacon sandwich on multigrain with tomato, tomato sauce/ avocado and pepper (that doesn't sound that bad to people who don't understand the diet) and I paid for it the next day with body aches and stomach upset. I am definitely staying on it!

After 7 years of extreme fatigue and doctors all telling me my blood work is fine, there's nothing wrong with me. This book explained about food intolerance's (not allergies) work in the body. I've finally regained my life after sleeping for seven straight years. This diet is worth the extra effort... and yes, it does take effort and sacrifice, but well worth it!

I wouldn't consider the gtd or btd to be a fad diet for fat people that wish to try and lose weight. It is a specific diet / lifestyle that is tailored to fit our unique phenotypes and blood compositions. It's a revolutionary way of looking at health and well-being

P.S. Uh oh. I apologize in advance if another very similar post to my one below appears later under the moniker "D'Adamo Fan". I tried to post yesterday as a non-member, using that moniker. However, the comment never showed up, so I assumed one has to be a member to post, thus I joined today, going by "BandGTD Aficionado", only to realize later that two other posts I did yesterday under "D'Adamo Fan" in the related review pages for "Eat Right for Your Type" and "The Genotype Diet" DID post, so if you all see similar posts to mine there, I apologize--those were from yesterday and I assumed they never posted, since the original one I attempted to post on this page never did. Sorry. Hope that made sense. Basically: I and "D'Adamo Fan" are one and the same. Sorry for any confusion.

I absolutely LOVE the Blood Type Diet, and Dr. D'Adamo's newer diet system, the GenoType Diet. I was on the BTD for years and relatively recently transitioned to the GTD. I cannot describe how profoundly this very customized, deeply nourishing, balancing, pure, whole-foods-emphasizing diet has benefited my health and general well being. I have learned so much in-depth, intricate knowledge about which foods, specifically, are excellent for me, and which are not my friends. This is not only a diet to help you acheive a healthy weight, it is a diet to help you acheive and sustain vibrant health, and that is what it is all about. I am never hungry on this diet, it helped me eliminate and understand (not in that order *lol*)cravings, it is a joy to eat this way, and I highly recommend it to everyone.

I sailed through a painless menopause at 47, finally resolved my adult acne, eliminated my chronic hip pain that woke me repeatedly all night, and went from a size 12 to a size 8 ! I have been Eating Right for My Type for 5 years and do not feel restricted in my eating choices, and have not yo-yo'd in my weight, I am still a size 8. I highly recommend this way of eating, what a healthy lifestyle. The Blood Type forums are a great place to connect with others who choose to eat well, and they are a warm, smart, welcoming group. Go for it!

"A fool knows little and says much....

A wise man knows much and says little..."

I have had my share of health and weight problems, my health and weight is the best its been for many, many years.... and I expect to be around many more years...

I owe my health (which is GOOD... NOW) to the BTD/GTD. As long as I have control of my eatings habits, I will follow the works of Dr. Peter J D'Adamo. thank you!

It is not a onetime lose some weight style diet. It is a healthy lifestyle change diet. I started with ‚??Eat right for Your Type‚?Ě, then learned my non-secretor status during the ‚??Live right for Your Type‚?Ě phase then graduated to the Genotype Diet, and recently had my personalized SWAMI done. I never looked back and am so grateful I found this lifestyle.

The Blood Type Diet is a great way to stay healthy and very easy to follow, it is not restrictive once you get used to it because you won't want to eat the "avoids" any more. I have dropped a pants size without even trying and do not have to work hard to maintain my health.
