"Immune Defence" pills, weight loss pills, "Raw and unprocessed wild blue green algae", etc.), and accessory equipment (blender, juicers, sprouters, and a mini-trampoline). She was censured in November 2006 by the Medicines and Healthcare products Regulatory Agency (MHRA) for selling unproven herbal sex aids. The products, "Fast Formula Wild Pink Yam Complex" and "Fast Formula Horny Goat Weed Complex" were both advertised as having been shown, in a controlled study, to promote sexual satisfaction. The MHRA found McKeith had been "selling goods without legal authorisation whilst making medicinal claims about their efficacy." The products have since been withdrawn. McKeith's website suggested the sex aids had been withdrawn because of European Union regulations. Goldacre contacted the MHRA, who said the removal had nothing to do with any EU regulations. Other television In 2007, McKeith presented Three Fat Brides, One Thin Dress for Channel 4, a competitive version of the You Are What You Eat format in which three women compete for a designer wedding dress. In addition to presenting her own TV shows, she occasionally appears in other programmes. She competed in The X Factor: Battle of the Stars, singing her rendition of "The Shoop Shoop Song". She also appeared in a health show transmitted on E4 called Supersize vs Superskinny. In 2009, she appeared on the W Network in Canada on Eat Yourself Sexy, in which participants claimed to have a diminished sense of sex appeal or sex drive, with McKeith employing the same practices as in You Are What You Eat. In November 2010, she became a contestant on the UK version of I'm a Celebrity... Get Me Out of Here!. In January 2016, McKeith appeared on Celebrity Big Brother as a short-term housemate, sent in to 'detox' the contestants. COVID-19 misinformation and conspiracy theories During the COVID-19 pandemic, McKeith opposed lockdowns and promoted anti-vaccination and COVID-19 conspiracy theories. She expressed her belief in a conspiracy of impending "martial law" and "fascist tyranny". She urged followers to refuse vaccines, referring to them as "clotshots", and instead suggested without evidence that nutrition could provide immunity against infection, prompting criticism from the British Nutrition Foundation and British Dietetic Association. In May 2021 she took part in an anti-vaccine protest at Westfield shopping centre, London. She spoke at another protest in July 2021 alongside conspiracy theorists David Icke and Piers Corbyn and again at a London protest that December. In November 2021
