Mosley is also known for his regular appearances on British television as well as his column in the Daily Mail newspaper. He has also made a number of films about diet and exercise. He also lived with tapeworms in his guts for six weeks for the BBC documentary “Infested! Living With Parasites .” Mosley has four children with his wife Clare Bailey Mosley, who is also a doctor, author and health columnist. She has written recipes for his diet books.
