Robert Lustig is a Professor of Pediatrics in the Division of Endocrinology and a member of the Institute for Health Policy Studies at University of California, San Francisco. He has authored 120 peer-reviewed articles and 70 reviews and is a leading voice on childhood obesity. And, his YouTube video “Sugar: The Bitter Truth” has been viewed over 7 million times. Obesity is a global pandemic. It’s astonishing how rapidly it’s expanding. And it’s COMPLETELY preventable. Lustig has dedicated his career to helping us understand the causes and how to “beat the odds against sugar, processed food, obesity and disease.” Big Ideas we explore include: Meeting the Darth Vader of the Food Empire (“Hi, sugar!”), two hormones driving the show (insulin + leptin), which fat you need to worry about most (big belly vs. big butt fat!), why so many diets work (reduced sugar + fiber), exercise (best ROI in medicine) and voting with ever dollar we *don’t* spend.
