Hi, Jumping In.
I pay £32.50 a week, for 3 meals a day (shakes, soups & bars (from your 2nd week)). You can also buy big pots of citrus & berry flavourings fro your water which are £6 each but last for absolutely ages, and something called Mix a Mousse, which you can use to turn the shakes into a dessert, which, I think was £2.90 or so.
I've been told that Lighter Life is more or less the same thing but for double the price you get concentrated counselling - and meetings too, I think. Personally, I didn't think I needed that - and would have found it awkward with a toddler. There are lots of forums for Cambridge, (to share advice, tips, experiences) plus, of course, the support thread here !
Do-able ?? Yes, of course it is, or they'd be out of business. It is hard though, not from being hungry (I can say hand on heart I've never felt hungry) but from being bored. Eating is so often a social activity, even at home with your family and you are of course excluded from that while doing this. I find it best to go and do something else while everyone else is eating rather than sit there watching them. Similarly, as we all know to our cost, eating is also a very emotional thing ..... I know I "treat" myself with food for example, and not being able to do so is hard.
I want to lose a total of 4 stone too. Have lost 2 stone 7 lbs in 9 weeks, so hopefully the end is near(ish).
Have a read through this thread - and CD threads 1 & 2 further down the board. This will give you a good idea of people's experiences and thoughts on the diet.
