Gok is back with yet another 'mission programming' format. The Wan is now exploring the rapidly growing problem of teenage obesity. On a candid and personal journey, he also addresses his personal teenage issues around food, and hears from leading experts about recent breakthroughs in tackling this national epidemic. Gok talks to young people and addresses the frightening extent to which they have been affected by food addiction. He tries to uncover why this age group is particularly susceptible to weight problems, while Dawn French talks about the body image pressures today's teens are facing. Gok also returns to his home town of Leicester, to his school and old family home, as he looks for answers to his deep-rooted relationship with food.
