About the show

Extreme eating

Documentary series in which two extreme eaters – one very overweight and the other severely underweight – swap diets in an attempt to change the way they view food and eating.

In the feeding clinic this time is Caribbean chef Gary Tomlin, who tips the scales at 137kg (21st 8lb), and Amy Simons, whose meal-skipping bad habits see her weigh in at 52kg (8st 3lb). Later, 34-year-old serial dieter Joanne Allan, who weighs in at 123kg (19st 5lb), meets 20-year-old fizzy drink addict Guy Sykes, in a swap that's packed with drama and tears.

Thirty-four-year-old junk food addict Jackie Kenworthy meets 70-year-old great-grandmother Beth Edwards, who lives on a diet of egg and toast. Later, takeaway fan Charlene Shattock, who weighs in at 140kg (22st), meets sugary tea addict Mick Wickes, who survives on one tiny meal a day.

Next in the feeding clinic, Joseph, a honey nut cereal addict who weighs in at 143kg (22st 7lb), swaps meals with breakfast-skipping runner Rebecca, who weighs in at just 48kg (7st 7lb).

Can they all change the way they view food and eating before it's too late?
