I have type O blood and was on a diet very close to the type O diet for many years, with cholesterol of 126. Then I had a heart attack and my physicians put me on a vegan (type A) diet, on which I have lost 60 pounds, but my cholesterol went up to 244. I'm concerned about the amount of saturated fat on a type O diet. Thanks. ANSWER
Not a problem (as you can tell) if you are using lean, organic meats and exercising. By the way, an increase in cholesterol in type O vegans is not uncommon, probably a response of excess insulin production (because, as my colleague Greg Kelly says, "Most vege-tarians are in reality starch-etarians."). Hyperinsulinemia has twice the risk factor for heart disease as elevated cholesterol and would be much more of a threat to you.
