Three of the Beatles became vegetarians: Paul McCartney, George Harrison and Ringo Starr. Starr became one for health reasons, Harrison for religious reasons (as a Hindu convert, though he later ate occasional chicken or fish), and McCartney out of his and his wife Linda's love of animals. John Lennon mostly followed a macrobiotic diet, but still ate meat on occasion. (He was a fan of Burger King's Whoppers, and also enjoyed sashimi.)

The late Linda McCartney published a series of vegetarian cookbooks, and later started a line of frozen vegetarian entrees. These made her independently wealthy, before her death in 1998.
