text:  Ian wrote this new memoir along with his sister, Aliza Carmel, who also cycled through fat diets, eventually pursuing a master's in nutrition and a doctorate in psychology to change the narrative on fatness. Ian has worked as a writer on Chelsea Lately, The Grammys, The Tonys, and Who Is America with Sacha Baron Cohen. And Ian Carmel, welcome to Fresh Air. Thank you so much for having me. It's wonderful to be here.
