Experts say mental imagery – that which we conjure ourselves and that which we’re presented with (in ads, etc.) – plays a sizeable role in our cravings. Have you ever found yourself victim to an ad’s suggestion? Even if you normally wouldn’t touch a particular food, those marketing folks have a fantastic way of making it look good. Our moods, of course, can influence our vulnerability to old favorites. Many of us have indulged in emotional eating, and carbohydrates figure into this equation all too strongly. There’s a legitimate serotonin boost from a carb binge, but then comes the inevitable crash and then the ongoing habit. Our desire for comfort foods, researchers have found, only increases with additional stress.
