Did your C tell you that? because in my opinion that is not true. I have had days where I haven't made the 1/3 superfree and lost. Granted- not lost as much as I usually do- but still a loss nonetheless
To be fair it was a while ago that I did SW in a club... But I did it when Extra Easy just came out and it was the one thing that left an impression.
Granted the C did not say if you don't eat a third SF food you won't lose weight. But I felt that was just a 'given' of the plan when I looked through the details. Whilst the text may say should (and I don't have this in front of me to check) I always take SHOULD to be a polite/friendly way of saying MUST. Draconian language "you must do this" and "you must do that" is most likely a diet clubs worst marketing ploy and I just assume they were using more friendly language in the book.
I'm forever telling my kids they should do something when I mean MUST - like they should wear a coat because it's cold!
Sometimes if you break down an EE day where you haven't eaten the SF food you may well really have is actually a Red or Green day that has gone slightly off plan, accounting for a poor or no loss. For example, homemade burger, bun, SW chips, baked beans. It is OK for a green day counting the bun as a b choice, the meat could be another b choice but if the portion is too large then the extra counts as syns. Maybe too many syns, depending what else you have eaten that day? The SF food, IMO, must be there for a reason otherwise it is really just taking the best of green and best of red and a little less cheese/milk and cereal/bread (for most everyday people anyway!).
Saying this, I will stress that I don't go to club now, my post was just my experience/impressions from when I did. Maybe someone who goes now can confirm with their consultant the importance of the SF third?
For the original poster, the diary you have given your consultant will most likely hightlight some tweaks that you might wish to consider to improve you losses. If not then maybe you'll see an improvement in the next couple of weeks. Quite often a stay the same week despite being totally on plan 'catches up' in the following couple of weeks. A small loss is a good loss - on one thread it shows what a pound of fat looks like and after seeing that losing even half a pound is worth having in my book! Good luck!
