Robert Lustig, MD: Is Higher Calorie Intake Responsible for the Obesity Epidemic?
Dr. Robert Lustig argues that average daily calorie intake has increased over the past 25 years and asks whether that rise explains the obesity epidemic. He cites population-level increases (men +187 kcal/day, women +335 kcal/day, teens +275 kcal/day versus 25 years earlier) and offers illustrative fast-food examples showing menu items rising from ~210 kcal (original White Castle burger) to as high as 2000 kcal (a Carl's Jr. burger) to emphasize larger portion sizes and calorie density.
