Hi
I did Cambridge all of last year and lost 7 stone with it.
My question to you is have you started the re-feed programme?
If you haven't, I would really suggest you do at least a week or two or the re-feed just so you adjust your body slowly to the carbs first (kinda similar to the above post really) because with WW you can have any foods you like (within your points) and after coming from a VLCD the carbs can really affect you if you haven't at least started the re-feed (or on CD gone up the plans bit by bit)
Of course, you can jump and it will force your body to have to adapt, but this can mean you will gain, not necessarily weight, but the scales can go up because of glycogen stores refilling so quickly and your body literally not being used to the food being in your body.
Whichever, you feel happiest with, go with, but just wanted you to have another side too
Good Luck xx
