"'Everyone who owns pet rats knows if you give them a cookie they will like that, but no one experimentally had given them all they want,' Sclafani told me when I met him at his lab in Brooklyn, where he continues to use rodents in studying the psychology and brain mechanisms that underlie the desire for high-fat and high-sugar foods. When he did just that, when he gave his rats all they wanted, he saw their appetite for sugar in a new light. They loved it, and this craving completely overrode the biological brakes that should have been saying: Stop.
"The details of Sclafani's experiment went into a 1976 paper that is revered by researchers as one of the first experimental proofs of food cravings. Since its publication, a whole body of research has been undertaken to link sugar to compulsive overeating. In Florida, researchers have conditioned rats to expect an electrical shock when they eat cheesecake, and still they lunge for it. Scientists at Princeton found that rats taken off a sugary diet will exhibit signs of withdrawal, such as chattering teeth."
