Which Comes First, Overeating or Obesity? Carbohydrates, Insulin and Metabolic Health

Commonwealth Club of California Podcast

Standard treatment for obesity, based on a law of physics, assumes that all calories are alike, and that to lose weight one must simply “eat less and move more.” However, this prescription rarely works over the long term. According to the Carbohydrate-Insulin Model of obesity, the metabolic condition of fat cells plays a key role in determining body weight. High intakes of processed carbohydrate raise insulin levels and program fat cells to store too many calories, leaving too few for the rest of the body. Consequently, hunger increases, and metabolic rate slows in the body’s attempt to conserve energy. From this perspective, calorie-restricted, low-fat diets amount to symptomatic treatment, destined to fail for most people. Instead, a dietary strategy aiming to lower insulin secretion promises to increase the effectiveness of long-term weight management and chronic disease prevention.
