It was horrible at first, like the first two weeks, but mainly I have what DP has and just nix the carbs, so chilli and rice becomes a chilli bowl with avocado and sour cream, stew I don't add spuds, curry no rice but I can have popadom as they are made either with lentil or chick pea flour depending on the brand etc.
I also learned how to make chick pea flour chips, pasta, pastry and crackers so I don't feel like I have to only have boring diet foods! DP says he prefers my chick pea chips, but I don't know if he is just being kind! 
And the weight drops off so fast it really keeps me motivated! I was a similar size to her to begin with but we are close in age and constantly compared so I like to be one up on her, which sounds mean, but we are actually good mates, she doesn't know she is my benchmark!
