We spoke with metabolic neuroendocrinologist Robert Lustig to discuss his views about the obesity crisis in our country. A powerful mind with a keen eye for digging deep into issues to explore their root causes, Lustig lays bare his critique of powerful forces at work that he believes negatively impact human health and longevity. His position is that added sugar is not a food and meets the criteria of an addictive substance like alcohol or narcotics. Addressing the physiology of metabolism, Lustig recommends lifestyle changes that, if practiced, could dramatically enhance our vitality. How did we get to this point in our obesity crisis? He emphasizes that fortunately there are corrective measures within reach, if we can muster the political will to enact them. What other "addictions" in a broad sense afflict our society? We touch on those as well. Join us.
