1957: Magazines and newspapers marvelled when Maria Callas managed to shed 28 kilograms in 11 months; they carried before-and-after photographs of her transformation from a frumpy 92 kilos to a slender 64.
Callas lost weight by strict adherence to a diet of one meal a day, small servings of fresh fruit and raw meat, no pasta, no bread and no alcohol. But when the opera singer later became infested with a tapeworm (probably consumed with the raw meat), gossip columnists gleefully suggested that she had deliberately swallowed it as part of a diet regimen.
