Reactive hypoglycemia and the Doctor says that the usual high-animal protein diet recommended for this kind of HypoG is exactly what is causing these hypoglycemic-like symptoms in some people (i.e. "toxic hunger") and that's exactly what was happening to me. I was misdiagnosed this whole time. I was eating so much meat because that's the only thing that seemed to provide any relief to my symptoms.
You don't have to juice fast to cure this toxic hunger. It's just what I did, partly because that Join the Reboot/Sick, Tired, and Nearly Dead documentary has been out promoting juicing to reboot your system. It worked really fast and good for me, so personally I'd recommend a veggie juice fast to get out of toxic hunger.
It only took me a couple of days juicing to get out of toxic hunger. I juiced for longer just to try to detox my organs.
