Why do we crave greasy food when we're hungover? Almost everyone craves a big ol' plate of greasy food after a night of drinking, but why? It's high in fat, high in calories, and you'd probably never eat any other time. The reason behind this craving is a brain chemical called galanin, which increases your appetite for fats. Since alcohol increases your body's production of galanin, you're going to want that big fat breakfast pronto.
