They were RANDOMLY assigned. (Sheesh, I'd hate to be one of the poor saps on Dean Ornish's plan. No fat, hardly any protein, and tons of carbs. I'd have thrown off their stats for sure...if I could have stayed on it, which I doubt.)

It sounds whacky to me. My stepmom lost 30 pounds this year on WW, THREE TIMES as much as these people. And that's with a surgery thrown in, during her recovery time she couldnt' exercise (which I think is CRUCIAL for a low fat/high carb plan to work.)

And who are these people? According to the NCS Pearson, they don't have enough of a sample size for a statistically significant result. Still, I'd say this was a bunch of slackers.
