Unnatural Hunger

You imbibe a drop of blood enchanted with necrotic energy, transforming your physiology to that of a ghoul. Your eyes sink, your teeth sharpen, and you feel starved regardless of how much you eat. All food looses its taste except for carrion, which you find unnaturally delicious. You gain nourishment from eating any type of food, despite its freshness or source. All nonmagical poisons and diseases found in the ingested foods are nullified.
