Fat Families is a British documentary reality show that was broadcast on Sky1 from 6 January to 30 December 2010. The weight loss expert and former health insurance adjuster Steve Miller helps overweight families to improve their lifestyles and eating habits, saving their lives as well as saving them money on their insurance premiums.
In each programme Miller initially spends 24 hours with the family and observes their diet on a typical day. He then spends the rest of the week educating the family about what they can do to lose weight. At the end of the week Miller modifies the family home to keep them motivated, such as removing TV sets and sofas, and selling them at auction, with the proceeds usually being donated to a relevant charity (i.e the British Heart Foundation). The families are then given a further 9 weeks to lose weight or face being sectioned under the Mental Health Act, and Miller gives each person a target weight loss.
Families are also revisited months later in episodes titled "Second Helpings" to see how they have progressed.
Fat Families was noted for Miller's presentation style and ruthless tone, described by The Northern Echo as "toe-curlingly honest with the people who take part in the show." The Guardian speculated that "the food-cam, phrases such as 'It's time to get off your wobbly bums' and the fact that Miller resembles a creation of Shirley Ghostman's Marc Wootton, mean it's got to be a spoof." In 2022 clips of the programme went viral on TikTok.
