Feirfalika hid the lost hair under her skirt. Although Sisi loved her hair, because of its heavy weight, it often caused her physical pain and headaches. Sisi was 172 centimetres tall but weighed only 48 kilograms.

She registered her measurements in her diary every day. At the Castle of Schönbrunn, Vienna, she spent one hour with strict training every day. She often rode a horse and took long walks whenever she had enough time. Rumour has it that she even had some of her ribs removed to make herself thinner, but this was never confirmed. Surprisingly, what she ate could be called anything but healthy.

The Queen only asked for food twice a day: in the morning and for supper around 6 pm. She usually ate chicken and beef, but there were weeks when only eggs and oranges were served for her. On the other hand, Sisi loved sweets and could not eat enough of them. After these eating-rushes, she usually did not have anything for days, which led Sisi to suffer from bulimia. The reason for her severe lack of confidence was her teeth and wrinkles. She rarely attended public events and dinners as she would not have had the opportunity to eat her usual meals. When Sisi did attend, she tried to talk as little as possible. It was not because she was not educated but because she was ashamed of her teeth. Sisi’s teeth had many health problems which were due to her love for sweets. When she talked, she usually held her hand in front of her mouth. When she became an old woman, she used dentures. Sisi also had a problem with ageing. During her old age, she only appeared publicly with a veil covering her face and forbid to be photographed after her 30th birthday.
