I've met several monks in my lifetime, even talked to them about how they eat a few times. All of them were in poor physical health, and looked much older than they actually were.

NOTE:
I am not trying to put down any religious groups. Also there is a big difference between the way some groups "fast", and juice fasting. Talk to any emergency room doctor and you will hear of several cases of people doing foolish things like juice fasting, and coming in to the emergency room with heart failure, blood clots, fainting, and kidney and liver damage, among other serious things.


BTW why is this post in the south beach section? It has nothing to do with the south beach woe, nor is it anything to do with low carbing in any sense whatsoever.
