The two people 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 21-stone eight, and Amy Simons, whose meal-skipping bad habits see her weigh in at eight-stone three.
Later, 34-year-old serial dieter Joanne Allan, who weighs in at 19-stone and five pounds, meets 20-year-old fizzy drink addict Guy Sykes, in a swap that is packed with drama and tears.

34-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, 22-stone takeaway fan Charlene Shattock meets sugary tea addict Mick Wickes, who survives on one tiny meal a day, for a diet swap packed with drama and tension.

In the first episode, a 22-stone honey nut cereal addict swaps meals with superskinny breakfast-skipping runner Rebecca, who weighs in at just seven and a half stone.

Supersize Vs Superskinny series seven airs from Sunday, 8 February at 20:25 on BBC Lifestyle, channel 174 on DStv.
