    Hey all! So i am one of the many who went low-carb paleo and crashed and burned. I was talking with my naturopath today and discussing how some people actually thrive for long periods of time on this type of diet and other, like myself, become ill. We discussed the possibility of blood types having something to do with ones reaction to a low carb diet. For example does someone with an O blood type do better than A+? So my question is, if you have tried low carb and it totally jacked your world, what blood type are you? I am A+.



    Carb digestion has more to do with AMY1 numbers than blood type – more AMY1 copies means more carb digestive enzymes in your saliva.

    The number of AMY1 copies is closely tied to genetics and ancestry… and so is blood type… so there may be a link to blood type as well, but it all comes down to your ability to digest carbs, which is all due to the number of AMY1 copies and amylase in your saliva.


    I’m a type O and did the paleo diet for 2 1/2 years. It made me sick!! I’m so much better eating plenty of carbs, so no, I don’t think it’s just a blood type thing. I think that maybe those people who are “doing well” on low carb are actually not doing well. They just have hidden problems. Maybe I’m wrong, but really, how good for the body can it be? I have wondered though if it’s a genetic thing as I certainly seem to need more carbs than other people. I have a friend who’s been on paleo for years and she seems to be thriving. But I still wonder. Is she ignoring how she really feels because she’s nice and thin? That beautiful figure can be very deceptive.


    Of the 8 main blood types, people with the type O have the lowest risk for heart disease. People with the type AB and B are at the greatest risk, which could be a result of higher rates of inflammation for these blood types. A heart-healthy lifestyle is particularly important for people with types of AB and B blood.
