There's something about the smell of a warm apple pie right out of the oven or freshly baked brownies on a summer's day. Though these smells make you want to drive to the nearest bakery, The Air diet expects you to do the opposite. How this diet works is that you sit down in front your meal; dice up your food into small portions; bring it your lips as though you're going to eat it, but you don't eat it. People on this diet mimic eating whenever they feel hungry so they can trick the stomach into thinking it's full. Once you've gotten a good whiff of the food you could've had, you actually fix yourself a bowl of salt water soup to eat instead; this way, your mind thinks it's eating steak and potatoes instead of the Pacific Ocean.
