I wish I was five kilos lighter than I am now, thinks director Mette Korsgaard. She wants to lose weight – just a little. It’s been like that for many years. In fact, almost all her life. In her youth, the body ideal was Barbie, Twiggy the model and Olivia Newton-John, and now that she’s grown up, it’s still the same. So at the start of a new year, she goes all in and tries a number of different diets to find out why it’s so hard to lose weight without putting it back on. Powder diet, pill diet, exercise diet. Over the course of the year, the instructor tries them all and, together with two researchers, investigates how the body and brain react along the way, providing completely new insights. A personal investigation into mankind’s destructive obsession with weight loss and excessive focus on kilos rather than health.
