Which is another reason why this study is not a particularly good one. In real life, people choose which way they want to eat to lose weight. Choosing for the participants practically guaranteed the results that they got simply through atrition. As someone already mentioned, I feel particulary sorry for the poor saps that got stuck with Ornish's plan. I don't think I'd make it through a whole week on that, maybe not even a whole day!
And...I'd still like to see the triglyceride results for the different plans since that would change the entire cardiac risk profile.
