The people I watched struggled with getting off the fast....mentally developed a fear of all carbs, and physically had problems adding them back in without weight gain/bloating. Nutricianal deficiencies -- posted a lot about additional supplements. THEN they cheated. THEN, they disappeared. LOL.

I think a lot of this is because of the lack of variety, yes. However, I think this is also alot like a starvation mode -- losing weight like this long term, the body gets starved for nutriants and will lock on to fat/water as soon as one tries to return to eating "normally", and eventually, hunger/cravings will kick in resulting in a binge.
