There's now evidence that some of our earliest ancestors also ate each other, and probably stayed slim doing that. We can be pretty hard to catch though so they probably did a fair amount of cardio along with their diet plan.
Seriously, I don't think there is much to this. If you have hit a plateau, you can search this site for a host of ways to break through it. In my case, I just had to wait those pesky things out. Be tougher than the plateau!
I'm type A plus too. In my case, if I haven't been able to lose weight it's because I haven't been able to step away from the chip and dip plate, not because I'm eating the wrong food for my blood type. Don't believe it.
It's all based on one letter written to a science journal in the 1950s. It was in a forum where older scientists would write about random ideas they'd had and never followed up on, so that younger scientists could get ideas for things that maybe they would want to study. One of the older guys wrote that he had always wondered whether blood type had any relationship to what type of lifestyle one's ancestors lived, and whether maybe as a consequence, there might be some value in trying to live a similar lifestyle now. In the very next issue, people wrote back with all sorts of reasons that it didn't make any sense-- people in the same family can have different blood types, blood types don't cluster very well geographically, blood types don't correlate with other physical features like body type... so many things that the original author wrote back in the *next* issue to say, "Yeah, y'all are right; stupid idea. Glad I never wasted any time trying to study it. Forget I said anything." It's the kind of thing that happens all the time in science. Even brilliant people have three silly ideas for every one brilliant one, and you get together with other brilliant people to help you sort them out.
Then about 5 years later they started seriously sequencing DNA from archaeological remains, and found out that the idea was completely off-- blood types existed before humans were humans.
The guy who wrote the "eat right 4 your type" hokum just picked the idea out of the air to make money. He even based it on the idea that O is the oldest type, but it's not. AB+ is the oldest and O is the most recent-- but it doesn't matter for that theory because all primates have the whole range of types. Having type A blood doesn't tell you anything. There were hunters with type A, gatherers with type A, farmers with type A-- no difference.
Some people do lose weight on the program. It has 4 relatively healthy (though restrictive) diet plans. But you will do just the same on the type O-negative plan. The diets restrict calories, and that's going to work regardless of your blood type.
If you *want* to try vegetarianism, there's no reason not to use that vegetarian diet plan. But if you're skeptical about whether you would want to give up meat, don't. What works is finding a plan that lets you control calories to a level appropriate to YOUR lifestyle, now, not to what your ancestors did for a living.

It isn't based on sound science, and is unnecessarily restrictive. This is a fad, not a lifestyle-changing diet. It doesn't take into account your individual history, needs, and preferences. It also changes based on your ethnicity, another pointless attempt.
For example, if I wanted to do this diet, I'd have to eat dairy.
I'm lactose intolerant.

Eat for your blood type...Do you believe in it? I have been having the hardest time losing weight....then a friend asked me what my blood type is. I am A+ which means I should be a vegetarian. I have never been a vegetarian and it would explain why I can't lose weight.
