Six celebrities opt for a sugar-free diet and earn healthy, wholesome food through work on a farm. Reality TV star James "Arg" Argent, Coronation Street star Tupele Dorgu, dancer Jennifer Ellison, singer Jane McDonald, comedian Rory McGrath, and Mark Labbett of The Chase fame take part in the two week-long dietary experiment. This week, the last in the series, sees Arg enjoy a break from farm life, but face a test of his convictions in Marbella. Meanwhile, dinner at a local pub challenges all the celebs to stick to their new diet. A month on from the trial, the six reveal if they’ve managed to star sugar-free.
