From an interview with Russian state media:
A. N.: Say what you will, but all weight loss is complete nonsense! When Callas began to lose weight, she began to lose her voice….
RG: Do you follow diets?
A.N.: No! Never! I love all of my extra 30 pounds, since Giuditta, who danced barefoot in Baden-Baden.
I’ve been keeping my weight up for the past seven years, I love it. I will not give it to anyone. This is what keeps me going. This is my stamina, my strength, to have something to support my voice. Of course, I’m talking about dramatic parts, not an easy repertoire.
RG: Has the fact that you have dramatically changed your role, having gone from a light, almost soubrette repertoire to the most dramatic roles, changed your character?
A.N.: No. In general, I became calmer, childishness with antics and mimicry has gone. I am already 45 years old, how much can you? I’m tired of acting, of representing all what I am not anymore. I find it much more comforting and interesting to work with big, serious characters.
