Well-produced documentation of VB64 here.
As interviewed by Nick Johnstone for the Guardian;
"When I was 12, I started to become a woman and my body began to change. I was devastated because I couldn't be a boy any more. I lost my boyish look. When I started to become something else, I didn't know how to keep it together. It was really painful - the more you eat, the more like a woman you become. That's when my obsession with food started. I felt very alone, but now I see that every woman in my family has an eating disorder. The anxiety of having eaten something and having it inside and not knowing how big and how much... I thought, I'm going to write it down and look at it and see if it's really so much. And one day, I might give it to a doctor so they will analyse if it's OK. But then it became an obsession and I wrote down everything I ate. I would go all day thinking, I ate an apple at 12 o'clock, I must write it down, I mustn't forget."'
