The Supersizers Go... and The Supersizers Eat... are two BBC television series about the history of food, mainly in Britain. Both series are presented by journalist and restaurant critic Giles Coren and broadcaster and comedian Sue Perkins.

The series originated in a one-off edition in April 2007 as part of a season of programmes on the Edwardian period, "Edwardian Supersize Me", a reference to the film Super Size Me by Morgan Spurlock. This programme set the format for the subsequent television series in that Coren and Perkins adopted the persona of a couple living in the Edwardian period and for a week ate the food which people from that period would have eaten. In addition they would take part in the interests and activities of them too, even going so far as adopting the dress and mannerisms of the time, with plenty of sarcastic humour. Before and after the experience they were subject to medical tests to see how the diet affected them.

As of 2 August 2010 the series was being broadcast on the UKTV channel Good Food. The episodes shown on Good Food were cut to 47-minute versions of the original, to accommodate commercial breaks. The series also broadcasts on Yesterday and Watch.

In 2011 a one-off royal wedding-themed special was broadcast in the same week as Prince William's marriage to Catherine Middleton.

As of January 2012 the show was in the United States on The Cooking Channel, shown with commercial interruptions. It was also on the Food Network in Canada.
