Her indulgent recipes and sultry delivery made her into television's most famous domestic goddess.
But Nigella Lawson is seeing her popularity wane in the face of the "clean eating" fad.
Miss Lawson, 56, has dropped out of the top 20 in the UK's latest cookbook sales chart, according to industry magazine The Bookseller.
Topping the list is the self-titled "body coach" Joe Wicks with his Lean In 15 collection of recipes and workouts.
Cookery writers Ella Woodward and Alice Liveing, who promote clean eating, are also sitting ahead of Miss Lawson and Jamie Oliver, who is 16th.
Miss Lawson's books have sold 210,528 copies - worth £2.6 million - since 2014.
