The Skinny on Obesity

Editor's Take

Centered on Robert Lustig and his UCSF colleagues, this series builds a case that sugar, not simple gluttony, sits near the root of the obesity epidemic. It works through hormones, metabolism, and the modern food environment in accessible terms, extending the argument of Lustig's widely shared lectures. The framing is pointed and partisan on a debated question, and it is clearest when explaining the underlying biology.

The Skinny on Obesity gathers Dr. Robert Lustig and his UCSF colleagues to examine the real drivers of the obesity epidemic, with sugar at the center of the story. Building on Lustig's widely watched lectures, the series digs into how modern diets, hormones, and metabolism combine to make weight gain so hard to reverse. It argues that obesity is less about willpower than about biology and the food environment. Clear and evidence-driven, it reframes a subject usually reduced to blame.
