Robert H. Lustig is an American pediatric endocrinologist and Professor Emeritus of Pediatrics at the University of California, San Francisco. A leading voice in the fight against obesity and metabolic disease, he challenges the food industry's role in driving chronic illness. His landmark book "Fat Chance" exposes the science behind sugar and obesity, while "The Hacking of the American Mind" explores how corporations exploit the brain's reward system. In "Metabolical," he dismantles modern medicine's approach to diet and disease. Lustig's research and advocacy have made him one of the most influential figures in nutritional science today.
