You Are What You Eat is a British dieting programme presented by Trisha Goddard and Amir Khan that broadcasts on Channel 5. The show was originally broadcast on Channel 4, before moving to Channel 5 in 2022 for its revived series. Both the Channel 4 and Channel 5 versions of the show were produced by CPL Productions (formerly Celador). You Are What You Eat was also the title of an American film from 1968.
