Interesting article and good for the girls!
I also followed a few other links on that site and read that Bob Harper has stopped being vegan because "his body just needed something more". Hmmmmm....sad that.
I heard a newscast on the way home from work stating that a recent study of overweight women showed that those who ate the most lean protein and consumed dairy products (as well as exercised) lost the most body fat and gained the most lean muscle. The message was clearly: eat your meat and drink your milk. BAH!!
