"Fat Chance: Beating the Odds Against Sugar, Processed Food, Obesity, and Disease" is a book by Robert Lustig, a pediatric endocrinologist. It explores the detrimental effects of sugar and processed foods on health, linking them to rising rates of obesity and related diseases. Lustig argues that these foods contribute to metabolic dysfunction and urges readers to reconsider their dietary choices. The book emphasizes the importance of understanding how sugar and refined carbohydrates impact the body. Lustig advocates for a return to whole, unprocessed foods as a means to improve health and combat the obesity epidemic, promoting a lifestyle change rather than temporary diets.
