Ok..here is what i can add to this topic. According to ER4YT I am a blood type O and therefore a meat eater. According to The Metabolic Typing Test ..I am a Protein Eater...they match up great for me. so there is SOMETHING to it. Those of you A's who didn't do well eating vegetarian..have you taken the Metabolic Typing Test..it is on this forum..someone posted the whole test. This test shows you are either metabolically a Protein Eater..A Carb Eater...or a MIxed type. For me Type O blood and Protein Eater go hand in hand..but maybe some of you A's are MIXED eaters...maybe check it out. Just a thought.
