Award-winning producer and filmmaker Michal Siewierski’s second full-length documentary The Yoyo Effect will debut this summer. The vegan film will focus on the obesity epidemic and explore common misconceptions of weight loss and trending diets such as Paleo and Atkins. From science-based evidence to new disruptive ideas, Siewierski aims to provide viewers with long-term sustainable weight-loss strategies to improve their health. “[My goal is to] empower the viewer with information that can set them on a long-term healthy weight loss path through lifestyle change,” Siewierski told VegNews, “instead of the typical short term ‘yoyo diets.’” The film will promote a whole-foods, plant-based diet and follow Siewierski’s personal experience with weight loss. “There is a message for both the non-vegan and vegan crowds,” Siewierski said, “as obesity is also becoming common among vegans that focus their diets on processed and high-calorie density foods.” The documentary features interviews with celebrities, authors, doctors, and health experts such as Physicians Committee of Responsible Medicine’s Neal Barnard, MD, plant-based ultramarathoner Rich Roll, and Whole Foods Market CEO John Mackey. Other vegan-focused documentaries such as Eating Our Way to Extinction and The Game Changers will also be released to the public later this year.
