I had been keeping out of this one, because I use the French book which is slightly different - albeit the ORIGINAL - but because yours is supposed to be a translation of mine, here goes.
Ok, sorry for the delay, I dug out my book (UK edition, 2010 translation): There is not much on yoghurts except that it has to be 0%. The dairy list on page 318 says:
- Non-fat quark/non-fat yoghurt (plain or flavoured with aspartame)
In the Attack section, pp 63ff he waffles on about yoghurts sweetened with aspartame and fruit:
-----------------------------
While aspartame and other flavourings have no calorie content and are just there to make yoghurt taste better, the added fruit introduces unwanted carbohydrates. This drawback is compensated by the fact that these gratifying treats give you the opportunity to enjoy a pudding and so can help you follow the overall diet programme. So that the instruction is clear, there are 3 sorts of 0% fat yoghurts: natural yoghurts, flavoured yoghurts (e.g coconut, vanilla, lemon) and fruit yoghurts i.e with little bits of fruit or a fruit purée base.
- Natural and flavoured yoghurts are both allowed without any restriction. (Anja personal comment: as long as they have NO ADDED SUGAR)
- Non-fat fruit yoghurts are allowed too but to a maximum of two per day. However if you want a lightning start to your attack phase diet you are better off avoiding them altogether and even more so if you are going through a period when your weight is stagnating.
-------------------------
Now personally I interpreted this as 'NO FRUIT YOGHURT' and stuck with it until Conso, it was much easier that way. The added complication being that most Fruit yogies have added sugar in the fruit preparation. And as we found most vanilla yoghurts have added sugar too. The 'flavoured yoghurt' detail is clearly aimed that the French market and was included without checking availability in UK. Ditto the 'two a day' - 'normal yoghurts are in the region of 100gr - 125gr pots, Mullers are 200gr - personally I would count one ML as two yoghurts.
Outside the book there has been additional advice from the offical dukan site (I think) regarding ML toffees (ie they're okay) etc, but I have no sources (but I have bought those in the past as well, and the Weight Watcher ones). I only added WW citrus ones in Conso because they too have bits.
This is only my opinion, you use the book as you see fit.
