To those of you whose immediate reaction is either "That's fantastic" or "Well Done", I have only one thing to say to you.
The longer version goes something along the lines of:
"My diet? Oh, let's see. Unbelievable stress, family upheavals, my mother dying, me having cancer, crappy self-care over the last 6 months, giving up the booze entirely, because it makes me nauseous (sob!), losing 100ml of blood and fluid every day into my shoulder drain, a major operation. That about covers it."
Rapid weight loss is not something to be applauded or congratulated. It is a sign of a physically or mentally unhealthy status.
And if anybody dares to even think "Lucky you, you can eat what you want", I always have. I have never been on a diet and I have never not eaten something because it is "bad" for me. I have maintained a weight that is within healthy parameters for my height for over 30 years now.
How's that for radical?
