I tell my friends that food and water are similar to me now. When I'm thirsty I'll drink, and the water tastes and feels amazing. Once I'm not thirsty, I have no desire to drink any water at all and it doesn't taste particularly good either. I also don't think about water when I'm not thirsty. Food is exactly the same way.

Usually this leads to a conversation about eating for pleasure, stress relief, or other reasons that are generally emotional.
