Supersize vs Superskinny is a British television programme on Channel 4 that featured information about dieting and extreme eating lifestyles.

In the second series, the "supersizer" was sent to meet a woman named Lisa, whose obesity had meant that she could no longer care for herself and was receiving an operation because of her weight.

Also, she discovered Diabulimia and spoke to Isabelle Caro, a French actress, renowned for her underweight figure and anorexia campaign.

In later series, formerly anorexic journalist Emma Woolf interviewed a number of people who had experienced the effects of eating disorders.

The second, third and fourth series also introduced a section whereby a group of people recovering from eating disorders (the second and third series featured people exclusively suffering from anorexia nervosa, while the fourth included a mixture of eating disorders) were overwatched by a specialist psychiatrist and dietician Ursula Philpot who co-presented Supersize vs Superskinny and who worked to challenge their issues with food.

During the first series in 2008, one feature involved Gillian McKeith, who tried to find a way to "ban big bums" in the UK.

[1] Clare Stephens, in an opinion piece written for MamaMia in 2022, expressed concern over the body shaming behaviours exhibited by the "superskinny" subjects of the programme towards their "supersize" counterparts, along with the behaviours of Christian Jessen, concluding that "at best, the show did a lot to confuse audiences about the relationships between eating and exercise and health and weight.

Regardless of what its creators may argue in its defence, Supersize vs Superskinny, as it exists on YouTube, holds no positive, constructive message.
