The document introduces the 'Eat More Index' (EMI), a new approach to weight loss that emphasizes consuming foods with high mass relative to calories, rather than simply counting calories. It argues that individuals can lose weight by focusing on foods that satisfy hunger while being low in fat and high in fiber, starch, and micronutrients. The EMI helps identify these foods, encouraging a shift towards whole, nutrient-rich options for effective weight management without feeling deprived.
