I have been taking the advice of the lovely Peli OTP and increasing my veg intake at the expense of bread. My lunch has been consisting of raw carrot, some pepper, a few plum tomatoes, some leaves (this week it's chicory) a bit of smoked salmon and a solitary slice of bread. I haven't been getting hungry and have been gradually shrinking. This is combined with a cake/beer embargo unless in a social situation.
I can't say I'm that keen on raw carrot and various leaves but I think it's got to be done.
