I tried the Cambridge diet for a while about two years ago, and although the initial losses were gratifying, it's soooo difficult to stick to - I have to just accept that I like food, and I enjoy eating. Since I stopped it the weight has come back, plus some!
I've also been on WW, both the groups and the online/postal plans, but the pattern is the same. I lose a reasonable amount,have even been virtually at target, but the weight always comes back again.
The 5:2 appeals to me because it isn't a 'diet', it's a new way of eating for life, and I can adapt it to suit my life, instead of having to adapt my life to fit my 'diet'. So that's my potted history, now on to my progress....
I only started 6 days ago, with a fast day, and I am planning to fast on Mondays and Thursdays in future. Bearing that in mind I weighed myself this morning, because I don't want my weekly weigh in to take place straight after a fast. I'm happy to report that I have lost 4lbs and my waist has gone down by 1.25". I know that this weight loss is because it is my first week, and I am not expecting it to carry on at this rate, but I am chuffed, and it has really given me a boost for week two
