In his new film Diet Fiction, US documentary film-maker Michal Siewierski (Food Choices, 2016) exposes why and how even the most popular diets on the planet do not work. The film follows Siewierski’s eye-opening journey through the controversial world of dieting. We see him introducing shocking facts and exposing misleading myths. Calorie counting, portion control and mindless training are gateways to unhealthy yo-yo dieting. Better, simpler and science-based solutions are within everyone's reach. It may not sound revolutionary, but fruits, vegetables and whole grains are really great. But how can you truly become friends with them? Diet Fiction shows you how by reviewing the marketing tricks of the diet industry; by just acting smarter we can improve our own health, support our loved ones and, ultimately, help save the entire planet.
