When the body is hosting parasites and is full of toxins - it is not receiving nor using the good nutrients from the foods you eat.
When the parasites and toxins leave - the body knows it needs to "catch up" on those lost nutrients - so sometimes it will signal hunger.
Much the same as when a pregnant woman craves certain foods that her body needs - watermelon in the dead of winter - ice (which indicates low iron) and so forth.
Just follow along with what your body is telling you - it will all balance out soon.
