Consider what would happen if you didn't eat when you're, say, feeling sad. You may, even on a subconscious level, believe that you'd fall apart if you let the sadness in or never stop crying, says Roth. Or you may think you just can't deal with your boredom. But give it a try once and see. "Allow yourself to feel the boredom, sadness, or anxiety," she says, "without using food to change the channel on what's happening in your life."
