Potato Substitute

Still trying to get some weight off, 13st 9oz (86Kg / 191lb) this morning, could do with getting below 13st.
For a while I have, on and off, been using CousCous as a substitute to potatoes, although potatoes themselves are fine as long as you don't put lashings of butter and cream in them of course!!
I did find the CousCous worked but then we get things happening which involve buffets and eating during the week of Marlanes sisters visiting and this tends to knock me back.
I'm determined now to make some effort so by the end of July I hope to be able to report that I've gone down a notch on my trousers belt!!
