What are the biggest concerns about the Blood Type Diet?

Andrea Giancoli (Registered Dietician ) gives expert video advice on: What is the overall analysis of the Blood Type Diet?; What are the biggest concerns about the Blood Type Diet?; Why is the Blood Type Diet considered a fad diet?

My biggest concern with the Blood Type Diet is that people buy it, and that they believe in it and follow it. I'm most concerned about the type O's, by telling type O's that they should be consuming mainly a meat diet. That's putting them at risk for heart disease, cancers, type 2 diabetes, and many more because a high meat diet is high in fat, saturated fat and cholesterol. We all know that those can contribute to some of these chronic diseases. If they're not getting the fruits, vegetables and whole grains that they need, they're not consuming some of those protective nutrients either.
