Starbucks has packaged salads with dressing on the side. She has probably noticed this when rummaging through the case. Without knowing any more than what she has posted in her blog and what was in that interview to which TAHbKA linked recently, I would say that this is the most probable explanation: She has said that she doesn't feel comfortable in the United States and misses Novogorsk immensely. The fact that younger skaters like Tuktamysheva and Sotnikova are now old enough to be sent to ISU championships only adds to the stress. I can see how she would use food restrictions to deal with her feelings. When she trains in Novogorsk, she can get all her meals at the canteen. In Simsbury, she stays at a hotel, and I have no idea whether it's one of those "suite" hotels that might have a kitchenette. Even though Leonova is an adult, her coach does bear some responsibility for making sure that she (1) knows what her options are for eating properly and (2) gets help if her eating habits are out of whack.
