Maria Callas
Weight loss

In the early years of her career, Callas was a heavy woman; in her own words, "Heavy—one can say—yes I was; but I'm also a tall woman, 5' 8 + 1 ⁄ 2 " (1.74 m), and I used to weigh no more than 200 pounds (90 kilograms)." Tito Gobbi relates that during a lunch break while recording Lucia in Florence, Serafin commented to Callas that she was eating too much and allowing her weight to become a problem. When she protested that she was not so heavy, Gobbi suggested she should "put the matter to test" by stepping on the weighing machine outside the restaurant. The result was "somewhat dismaying, and she became rather silent." In 1968, Callas told Edward Downes that during her initial performances in Cherubini's Medea in May 1953, she realized that she needed a leaner face and figure to do dramatic justice to this as well as the other roles she was undertaking. She adds,

I was getting so heavy that even my vocalizing was getting heavy. I was tiring myself, I was perspiring too much, and I was really working too hard. And I wasn't really well, as in health; I couldn't move freely. And then I was tired of playing a game, for instance playing this beautiful young woman, and I was heavy and uncomfortable to move around. In any case, it was uncomfortable and I didn't like it. So I felt now if I'm going to do things right—I've studied all my life to put things right musically, so why don't I diet and put myself into a certain condition where I'm presentable.

During 1953 and early 1954, she lost almost 80 pounds (36 kg), turning herself into what Rescigno called "possibly the most beautiful lady on the stage". Various rumors spread regarding her weight loss method; one had her swallowing a tapeworm, and Rome's Panatella Mills pasta company claimed she lost weight by eating their "physiologic pasta", prompting Callas to file a lawsuit. Callas stated that she lost the weight by eating a sensible low-calorie diet of mainly salads and chicken. Callas never regained the weight she lost and kept her slim figure until her death.

Some believe that the loss of body mass made it more difficult for her to support her voice, triggering the vocal strain that became apparent later in the decade, and others believed the weight loss effected a newfound softness and femininity in her voice, as well as a greater confidence as a person and performer. Tito Gobbi said,

Now she was not only supremely gifted both musically and dramatically—she was a beauty too. And her awareness of this invested with fresh magic every role she undertook. What it eventually did to her vocal and nervous stamina I am not prepared to say. I only assert that she blossomed into an artist unique in her generation and outstanding in the whole range of vocal history.
