『The End of Overeating』要約

In *The End of Overeating*, former FDA commissioner David A. Kessler investigates why so many people feel powerless around food, arguing that overeating is not primarily a failure of willpower but a conditioned response engineered by the food industry. Drawing on research in neuroscience and behavioral psychology, Kessler describes how combinations of fat, sugar, and salt are deliberately layered into processed foods to create what he calls "hyperpalatable" products that trigger reward circuits in the brain. He uses the term "conditioned hypereating" to describe the compulsive patterns that develop when cues—sights, smells, locations, even times of day—become linked to the anticipation of highly rewarding food. Kessler reports interviews with food-industry executives, scientists, and former FDA colleagues, along with visits to restaurants and manufacturing facilities, showing how chains design menu items for maximum "craveability." He profiles people who struggle with weight and traces how repeated exposure rewires their responses, making certain foods feel irresistible and consumption automatic. He also examines the biology of reward, including dopamine signaling, and explains why the mere thought of a favorite food can set off a cascade of desire. The book's second half proposes a way out, which Kessler calls "food rehab." He outlines strategies such as identifying personal trigger foods and situations, changing the environment to reduce cues, planning meals in advance, and rehearsing new responses so that old associations weaken over time. While acknowledging that willpower alone is unreliable, Kessler argues that understanding the conditioning process allows people to disrupt it. Published in 2009, the book became a bestseller and helped popularize the idea that the problem lies less in individual discipline than in a food environment purposefully built to encourage excess.
