Inspired by the trendiness of intermittent fasting in the tech community, Kara Swisher's executive producer, Erica Anderson, talks with three eating habit experts — a biohacker, an academic, and an eating disorder specialist. In this episode: HVMN CEO Geoff Woo on the culture of body optimization, the mainstreaming of biohacking, and how humans are "approaching God"; aging and nutrition expert Dr. Valter Longo on the origins of biohacking, the science behind intermittent fasting, and the problem with Silicon Valley's interpretations of the practice; and the executive director of the National Easting Disorder Association, Claire Mysko, on the line between eccentric diets and disorders, the wellness industry, and what to do if someone you know needs help.
