I think the doc just wants to show her it works. He's had other patients that lost a lot of weight on this meat/cheese only part (he calls it Phase I).
I'm fairly certain there is no medical reasoning for his no veggies idea. I think he's just used this weightloss plan with people and it's worked. Who knows, maybe he's trying to pass this pseudo-atkins diet off as his own?
We discussed it and we think we're going to stick with 20g's or less/day, because for one, it's working, and secondly, we figured that she'd be LESS likely to stick with a meat and cheese only diet because we are SO over meat and cheese at this point!
