Excellent post. I recently became very ill while fasting and immediately stopped. I ended up going to the dr. and taking prescription drugs - something I don't do often. I don't think there's anything wrong with fasting, I think that for whatever reason, my body didn't handle it well because it was/is too toxic at this time. In the spirit of listening to our bodies and bringing them to optimum health, it seems strange that someone would become so fixed on a diet that they can't see the harm it's doing to them. I hope "John" thinks about what you had to say to him and gives his body the nutrients it's crying for.
