Imagine being told all your life that eating is disgusting. Food is greasy and gross and foul, yet you cannot avoid it; by your nature you desire it, and must needs ingest it, slurping and farting and rotting your teeth and loathing yourself for satisfying the persistent urge. Curse your nature, therefore. Vomiting is a virtue. You do not suspect, and nobody around will tell you, that there are cuisines and commensalities, techniques, arts and refinements, that have long been cultivated beyond your limited horizons.
Then you discover the Jesus Diet. It doesn't open your eyes to the delights of food, but it does allow you to turn all that self-loathing outward.
