What’s really causing America’s obesity epidemic? In this special debate episode of The Metabolic Link, two leading voices in metabolic health square off: Dr. Richard Johnson, renowned for his research on fructose metabolism, and Dr. Layne Norton, a PhD in nutritional sciences and expert on the energy balance model.

Moderated by host Dr. Dominic D’Agostino, the discussion dives deep into the biological roots of obesity, the relevance of sugar-sweetened beverages, the role of leptin and uric acid, and whether it’s fructose or calories that are driving the crisis. Despite their differing perspectives, both experts agree on one critical point—our modern food environment is fueling metabolic dysfunction on a massive scale.

This is one of the most nuanced and constructive conversations you’ll hear on the topic of obesity science.
