I watch Food Network shows as "food porn". I watch Cupcake Wars, Challenge, Good Eats, and Unwrapped. It makes me want to eat sweets, but I usually don't. I can almost taste the food as I'm watching it get made, but after the show is done, I don't really feel the need to go eat cupcakes or anything.
It's odd, but it also gives me strength to resist indulging.
