Is it possible to be both fit and fat? #BBCNolan

Is it possible to be both fit and fat? In this weeks Daily Mail there was an article about three overweight women who claim that yes you can indeed be obese and still be healthy. Between them, the women run marathons, compete in Ironman competitions and teach others how to get fit. However, rather than svelte size 10s, their weight ranges from 14 stone up to 20 stone. They believe when it comes to fitness, size doesn't matter. Are these 3 plus-size women living proof you don't have to be thin to be healthy? Or is working out not enough? Can you really be overweight and still fit? Stephen was joined by Niamh Horan, size acceptance campaigner Kathryn Szrodecki and nutritionist Jane McClenaghan
