A recorded talk by Robert Lustig (uploaded by Dr. Ron Najafi) examining the relationship between calories, diet composition, and weight loss. Lustig notes that while many diets can produce weight loss (supporting the view that 'calories count'), that simple energy-balance model is also challenged: ultra-processed foods — particularly those high in sugar — promote overeating because sugar is addictive, so food quality and food processing contribute to weight gain via increased intake. The clip contrasts the ‘‘calories-only’’ model with evidence about processed foods and addictive effects of sugar.
