Thank you everyone. Sorry, I completely forgot to put my height! I am 5 ft 4. The weight's coming off very rapidly at the moment, and I take that to be a sign of it needing to go: I lost 5 pounds at the weekend without even trying! I can completely see what you're saying, and I think many of you are right in that I ate 470 yesterday and I couldn't really function today. I'm increasing the calories to 600, which I appreciate is still not much, but to be honest I don't feel I need that much. My question is really: is 8 stone a good weight for a girl of reasonably petite frame with a height of 5 ft 4? As I say, I am a vegan (so my dietary habits are different), and am highly active...?
