“The government can come along and, with all the best intentions, cause enormous problems” says Gary Taubes, a science writer and author most recently of Why We Get Fat And What To Do About It .

Reason.tv’s Zach Weissmueller talked with Taubes about his controversial work in the world of nutrition and epidemiology, including Taubes’ hypothesis that carbohydrates, not dietary fat, overeating, or lack of physcial activity, are the primary factor causing obesity. Other topics include the inability of governments and large informational institutions such as the American Heart Association to adapt to new information, the mess of bad legislation and bad science that Taubes believes led to America’s obesity problem, and why many libertarians seem to love the Paleo Diet.
