Dr Christian Jessen has opened the doors to his ‘feeding clinic’ for a seventh series. As the title suggests, a ‘supersize’ and a ‘superskinny’ take part in a diet swap to experience what the other eats. The aim of the game is to highlight the severity of the British public’s awful relationship with food. But that’s just it – it’s a game.

I will admit that I’m addicted to the programme, yet the reason I tune in is because all I want to do is criticise. View it as a light-hearted diet game show, and I would give it full marks. My issue is that it goes back and forth, breaking up the diet-swap (ending with participants having a rapid epiphany about their bad habits) with a feature about people who have been battling eating disorders for years.

It begins with a (not exactly positive) portrayal of America, where Jessen “brings our supersizers face-to-face with some of the biggest people on the planet”, to discuss extreme weight-loss surgery. The issue arises when the next section, about eating disorders, is introduced by saying: “At the opposite end of the spectrum…” This harmfully confuses diet with disorder, ‘superskinny’ with anorexia, not to mention that it ignores different types of eating disorder where the person is not necessarily underweight. In previous series, this did more harm than good.

However, the section in question is more effective this time round. Presented by Emma Woolf, we hear from sufferers who are currently in recovery, and from experts working in an in-patient unit. Woolf’s feature is sincere – an inquiry rather than an intervention. Her aim is to discover why certain people are more prone to having an eating disorder, not to reveal the world of extreme weight loss to children.

If the point is to prove that the superskinny can gain weight, and the supersize can lose weight, then the show is a success. As an ashamed fan, I can’t help but hope that there will be an episode where we follow Dr Christian Jessen to discover what he eats, as I’m still confused as to what a ‘normal’ diet is.
