Didn't keep to the 500 cals but still consider it a fast day - felt very hungry all evening so did have 2 apples and 2 pieces of chocolate. I melt the chocolate, it seems much more satisfying and tasty that way!!! (I previously tried a protein bar as an alternative to chocolate, but it was not as satisfying and seems to be full of more synthetic ingredients than chocolate is...)
Don't feel hungry yet today, but probably will have a late breakfast.
Best wishes to all!
