Looking at just the desire to eat, it could be composed of two parts, one a instinct and secondly, a mind parasite that sits there saying eat, eat.
Religions are mind parasites, and could this eat eat thought in the mind be something similar? Abandoning any concept of god, god is just a concept other people have, type of thinking is freeing, at we ratchet toward truth, is freeing and truth seeking. Stoic philosophy is good, as far as it goes, but it stops short of solving the problems of the world. Some problems just have no solution though.
We can believe wrong concepts, and these concepts take up residence in our mind. There is nothing we can do until we recognize these as wrong concepts, mind parasites. Then we can root them out. Perhaps it is as simple as liking food too much, over driven reward, or the only reward we like. Perhaps is is the desire for more energy, that has twisted us to eat. But perhaps it is just a mind parasite of the conceptual class.
