because I work in a blood donor clinic. I'm not a nurse but there have been many lively discussions about this subject as I'm sure you can understand because we have people calling all the time just wanting thier blood type to do this diet.

The basis for the research is that O's originated at a certain time in history and from a certain area of the globe, and then A's came along in another place and time, and on and on. There is absolutely no scientific research to back up the theory behind this book. Sorry to say...

I'm also an A and could not be a vegetarian for all the money in the world. I love meat and will never go off this WOE even if I never lose another ounce. I feel 100% healthier than I did a month ago.

ER4YT is a crock as far as I'm concerned, and will continue to think so until I see some proof to the contrary. (Sorry to be so blunt, been that kind of day.)

So, there's my un-official opinion, not that anyone asked.

Cheers!
