I lost 2 stone in 5 months following SW and because I could eat so much food I never even realised I was on a diet!! It just became a way of life. And to lose 2 stone into the bargain was simply amazing.
Friends would come up to me worried and say they were concerned that I was losing a lot of weight and I wasn't eating properly. The joke was that I was eating probably more than they were, but all of my food was low fat hence the weightloss!
Being slimmer changed my whole personality. I had more confidence, energy and was so much happier. Wearing slimmer clothes, and feeling nice when you walk is so much better than any bar of chocolate.
