They do have an online version!!
They work on the basis that if food is forbidden then that is the one food you want, and if you don't have it then eventually you will fall for the temptation and eat it, lots of it, and then feel bad and a failure so you give up altogether.
The idea is that you eat loads of the free foods (mostly fruit and veggies, also lean meats), then you have one heathly choice a day from two categories - dairy (some milk or cheese) and the bread category. That really keeps you pretty full. Then if you know that you can have a little chocolate each day, but you are really quite full, you will have less and then carry on with the diet. Yesterday dd and I shared a twix and a twirl - both two finger bars so we had a finger each. For me that came to 12 syns - and I enjoyed it without feeling bad. If I wasn't doing this I would probably have eaten the whole of both the bars and then maybe gone and got some more chocolate from somewhere. I was able to refuse the offer of choc chip cookies too, because I really felt quite full.
It does mean more cooking from scratch for me - but that is what I've been trying to do for a while, this gives me an extra impetus and there are easy plans for me to follow so I don't have to work out all I need to get and plan for the weeks food. I'm excited! I think this might actually work for me!
