There's an entry in American Popular Songs, by David Ewen (Random House, 1966):

O Katharina!, words by L. Wolfe Gilbert to a melody by Richard Fall, distinguished Austrian operetta composer (1924). "O Katharina!" was written for and introduced by Nikita Balieff, the genial, round-faced master of ceremonies of the Russian revue Chauve souris, imported to New York from Paris in 1924.
L. Wolfe Gilbert has explained: "My song was as timely then as it is today. Since the American woman was diet conscious, I wrote 'O Katharina, O Katharina, to keep my love, you must be leaner.' I spent two weeks rehearsing him [Balieff].... I asked one chap how Balieff sang the song. 'He didn't sing the words,' the stranger replied. 'He just kept singing the title over and over until he had most of the audience singing or whistling it."
