The Diet Industry

Dieting is often presented as a private choice, but its history is one of the great public stories of modern life. The Diet Industry traces how the business of losing weight grew from early ideas about appetite, fasting, body discipline, and medical regimen into a vast commercial world of calorie charts, slimming clubs, celebrity diets, low-fat products, low-carb revivals, superfoods, clean eating, fitness culture, body-image anxiety, wellness influencers, apps, and wearable trackers. This is not a diet plan and gives no medical advice. It is a factual, narrative history of diet culture: how food became moralised, how the body became measured, how advertising turned insecurity into opportunity, and how each generation found new language for the same old promise of transformation. From William Banting's nineteenth-century pamphlet to Hollywood glamour, from wartime rationing to postwar supermarket abundance, from Weight Watchers meetings to social media wellness feeds, this book follows the people, products, ideas, and industries that made weight loss one of the most persistent businesses in modern culture. Clear, accessible, and carefully non-prescriptive, The Diet Industry tells the story of science, commerce, fashion, gender expectations, public health, celebrity influence, and the long human desire to reshape the body.
