Georgetta and Ameer

Promotions girl Christine thinks her diet is healthy because she's following the government's advice on eating fruit and veg. At the opposite end of the scale is Martin, who's living on fatty, starchy and salty junk food. Dr Christian Jessen oversees their dietary wake-up call, while Anna Richardson shows the Flab Fighters how to combat their crisp calorie cravings by trimming the maze at Longleat. Anna then heads to LA to prepare dishes for a celebrity meals-on-wheels service and meets the A-lister personal trainer who keeps Hollywood stars red-carpet ready.
