I never get tired of hearing about the transformative power of this way of eating. I am particularly impressed with the vegetarian O's who begin to eat meat and find out how good it makes them feel both physically and emotionally. To go from being a vegan or vegetarian to eating meat takes a great deal of courage. Vegetarianism/veganism is not only about meat but usually about a worldview as well. I have a personal experience with this, I have a sister who is a type O and has chosen to live as a vegan. My only hope is that one day she will understand this way of eating and embrace it. I love her dearly and over the past few months she has experienced some health challenges, that I know the type O diet would help.

I like to read the results database here on the website because these are people who wrote something because they wanted to, not because they had to. All these quotes are from blood type O's who were vegetarians and converted to a Type O diet which includes meat. It gives me hope to read their stories.

I was a former vegetarian and told my husband that I would give the diet six months - if I didn't see any improvement it was back to vegetarianism for me! I very gradually started adding meat back into my diet and decreasing grains (especially pasta). I started noticing a definite improvement in my energy levels within two months.

I have gradually worked my way into this diet. Before I began, I was an overweight, fatigued vegetarian, and constantly coming down with various illnesses. After hearing and reading a bit about the diet, I began eating meats (particularly lean reds and fish), and modified my other eating habits according to the plan. Over the past year and one half (when I began modifying my diet), I have had no significant illnesses, I've lost weight, I have constant energy, and I have a better sense of well being. I have even felt a greater hormonal drive. My life has really taken a 360 degree turn since I began the diet.

After being a vegetarian for 10 years I noticed a boost in energy and a better sense of what foods cause positive or negative results in physical or mental/emotional states. I also noted that my hayfever symptoms and morning stuffiness has been diminished or eliminated completely.

"Eat Right For Your Blood Type" is amazing! I have tried vegetarianism for a while and, until now, never understood why my health failed to improve norwhy I failed to lose a significant amount of weight. I was diagnosed as a Type 2 diabetic about a year ago and controlling my blood glucose level has been a struggle, to say the least. Having tried just about everything else, I decided to purchase the book and give Dr. D'Adamo's dietary advice a chance. At first, I must admit, I was skeptical because "After all, all humans have the same digestive system, don't they?". Nevertheless, I was intrigued. Now, I'm excited to experience more energy and lower blood glucose levels after following the Type O diet for a mere few weeks. Also, I have eliminated indigestion, heartburn and flatulence by simply avoiding wheat and corn products. I now eat small amounts of grains such as spelt, kamut, barley, quinoa, buckwheat, rye and brown rice

I have followed the diet for 16 months, I'd say 13+ months quite rigorously. I'd like to add the "more energy, well-being" catagory as well, but not sure if you can select more than one. I'm 42, and had been a vegetarian for 30 years (absolutely no meat, did do small amount of fish, eggs, and lots of cheese.) I've always been athletic and lean,(no weight loss was needed) and into healthy eating. I can't hardly describe the change I have experienced! It is very near the top of the list of most important things that have happened to me in my life. I am in the same body, look about the same, but FEEL COMPLETELY DIFFERENT. I constantly have the thought, "this is amazing, so this is how (some) other people feel. I wonder what I would have done in this last thirty years had I felt like this?" I recently visited a woman (now 79) who has known me since I was 12 (when I became a vegetarian), and she could definately see the change. She said I had been "the most ethereal person she had ever known" and she used to worry about me- "that I would just float off." As the months go by I continue to BE AMAZED by the new territory in my psyche, GROUNDED, FIRM, CLEAR, ABLE, with lots of SPACE to move around in and OPPORTUNITY for CHOICE. It's like having a new brain or an expanded being. I wasn't at all a basket case before, but this is a GIFT of EXTREME GRACE. I am a total advocate and I CAN'T THANK YOU ENOUGH! THANK YOU THANK YOU THANK YOU

I realize you must be swamped with mail, but I wanted so badly to thank you for how you have helped me. I have suffered from anxiety & depression to the point that several years ago I lost the ability to work, and was hospitalized for a short time. I was able to get back to work thanks to lithium & welbutrin, which I took for years, but though I was very grateful to be able to function again, I noticed that even on antidepressants I never really was happy to be alive, mostly just dreading the long, long life that I figured I'd probably have to "get through, somehow." Because of this, I never really considered myself really back to full health, & kept trying everything from homeopathy to supplements to feng shui. The only of those that seemed to have some positive effect was flax seed oil. Then I read your book & was very dismayed, as a long time preferred-(non-rigid)-vegetarian, that I was a type O! It really rocked my world for a while, but I had so many of the other problems you mention O's usually have that I determined to tryit & see, since I am nothing if not open-minded. The first thing I noticed was that I was not constipated in the morning if I'd eaten beef the day before (something loads of metamucil could not even guarantee.) To my surprise the morning aching in my hands went away within weeks as well all my colon problems (gas, generalized abdominal pain, previously diagnosed as all kinds of things, IBS, & occasional bloody diarrhea.) I also notice that I do not have the "drowsy" spells after lunch that I used to have. After a few months I realized I hadn't had any attacks of the fibroyalgia in my calves that I usually have on the colder, damper days of winter (I'd always considered these things minor because it was the depression which affected my ability to earn a living.) I now feel "all the way back" from depression, and then some, because not only do I now look forward to the rest of my life (finally!) I feel so much stronger & enjoy physical exercise in a way I never did before. I actually feel exhilarated by it. I am still taking about 1/2 the dosage of St. John's wort that I used to require, & I know you don't recommend it for O's, but with all I've been through, I'm a bit chicken to go off it just yet. I've been following your diet pretty strictly for 5 months now & I think before the summer sun becomes intense this year I will let go of the St. John's wort & see if I still feel fine. One of the best results is that for the first time since I was 18 I have not had hayfever in the spring. It used to be quite severe. I am hoping that I will be less allergic to poison ivy this summer as well. I am taking quercetin also. Recently I noticed that I really do seem to be physically stronger & have more endurance. For example, I could never do a single chin-up & now I can.One rather strange thing I noticed is that when I started eating meat my voice changed from very clear to a bit gravely & has never changed back. (The week I started the O diet I got a bad, week-long case of laryngitis & maybe the voice change is more from that.)When I try to spread the word about this great book of yours I sometimes encounter fear & hostility because it seems so many of my type O friends are vegetarians. Some people would rather keep their long cherished beliefs than their health. But I thank you from the bottom of my heart because your father's & your work has helped me so much. By the way, I am 43 years old, & ate primarily vegetarian for the last 24 years.

Dedicated to all the blood type O vegan and vegetarians, may you find health and wellness.
