When I think of a fast, I imagine someone not eating and drinking only water and/or tea.
Perhaps they are taking some type of vitamins as well.
But, I doubt that this is what she did for 2 weeks (because she was after all speaking to a teenage audience).
I personally think it's irreponsible of her to do such a thing, because kids can be very impressionable.
This left me wondering, what are the different meanings behind the word fasting?
