On May 11, 2010, at the 2010 Nutrition & Health Conference in Atlanta, Georgia, medical doctor and former Food and Drug Administration commissioner David Kessler explains that the only way Americans can overcome our “conditioned hypereating” is by changing the emotional “valence” of the powerful food stimuli that bombard us daily. Kessler is the author of the best-selling book “ The End of Overeating: Taking Control of the Insatiable American Appetite.”
