I read the book about it and it was very interesting to me.
Being O+ I am suppose to be eating mainly meat and doing
physical challenging exercise. My brother-in-law’s diet is by
this book and he eats mainly salads. He would LOVE to have
my o+ diet of eating meats and I would LOVE to be eating mainly
salads and not much exercise. I just do not eat much meat even
though we sell all natural meats that come right off of our farm and
it is delicious! I just did not want to change my eating habits even
tho my blood says I should!

I’m type O.

They want me to avoid caffeine and alcohol.

They can fuck right off.

@Seek I second that!
I don’t drink a lot but I will never give up my coffee!

I don’t believe in the diet. I would never try it. Plus, you get your blood type from two parents and you can be a blood type without knowing which two you received from your parents. A can be AA or AO. The parents of A can be AB and AA, or AA and AA, or AO and OO, or AO and AB.

An AB person can be from parents who were AB and AB, or AA and BB, or AO and BO, or AO and BB, or AB and BB, there are more combinations.

If you are O your parents could be AO and BO, or OO and AO, or OO and BO, or OO and OO.

I mean really when you considered how mixed it is through the generations, not to mention how mixed the population is more and more, I don’t see how an individual can look at just blood type regarding diet. It’s just one thing among a ton of other genetic things.

I don’t think there’s any evidence to support the claim that blood types affect how someone metabolizes their food… and I’m having a hard time imagining how that would even work. At the very least, he is probably oversimplifying minor correlations in complex processes to the point of inaccuracy (if his research even uncovered any correlations at all; I didn’t look at it, but I’m dubious). As long as someone is getting balanced nutrition, exercising, and cutting their caloric intake with these diets, they’ll probably see results they like—but probably not because a diet matched their blood type… those three things (nutrition, exercise, lower caloric intake) have been the three things research has time and again shown to be effective for everyone… and the trick for someone is to find what they can stick with.

I don’t believe in diets period nor do I even know my blood type but out of curiosity I did some light reading on this concept and am NOT convinced it’s legit based on what information is available on the internet.

1.) Sensibly, the specifics of Peter J. D’Adamo’s research is exclusive to his own publication or it wouldn’t sell, however, what I did find was that the claim is that the food we eat has a chemical reaction to our blood that varies by blood type causing some foods to be naturally incompatible with our bodies.
The Internet publishings provided little explanation beyond that statement, they mostly just get right to mapping out the categories and in what was provided the science seemed to overly complicate something simple though I’m no science genius.

2.) It doesn’t account for several individual dietary restrictions caused by conditions such as food allergies, diabetes, acid reflux nor ideals based on medical history such as a need for cholesterol control. Nor does it account for target weight.
There is also the necessity for protein. The categories restricting a great deal of meat are depriving the individual of natural protein.

3.) The blood type categorizing is in part ethnicity based which is absolutely absurd.

4.) Blood type isn’t black and white. Even two individuals with the same type have differences because they each got it from different genetic recipes based on their parents’ blood types. Let’s take the asker’s O+. That could have resulted from AO and BO, OO and BO, OO and AO or OO and OO parents. O also happens to be the universal donor and recipient. All bodies are compatible with O and Os are compatible with all types.

5.) Moderation of desired eating habits and exercise have shown more effective results that anything else probably because it accounts for the fact that every single body is different in more ways than one. Hence why I put my faith in it rather than any diet.

The human body needs about 40 nutrients. No researcher ever suggested that nutritional needs might depend on any detail other than heredity. There is a constant current of bad science and people in general are quick to believe bullshit rather than to read a book and learn some actual knowledge. One thing everybody agrees on is that diets don’t work reliably, but diet books are still as popular as pornography. There used to be a magazine, “Prevention”, dedicated to touting current nutrition research. They finally gave up and now they tout fad diets and unproven medications.

Bottom line: You have to learn the subject yourself.

I have read an old book on that idea, but found it to be be just a gimmick to sell books.
I lost weight by reducing my intake of each meal by one quarter of what I usually ate. and starting walking more often, taking the stairs at every opportunity instead of the elevator, then progressed to biking, and hiking.

These books are still the most popular introduction to nutrition.

Bear in mind they were written around 1960 and some things have been learned since then. For instance she recommends to mix veggie oil with butter, but doctors now recommend to use butter straight.
