Ok so just checked out the link from Linda and I can see why it has been taken off the list of recommended drinks, although I see also that it is not banned, but rather is "not recommended".
Coke Zero has less than 2kcals per 500ml so less than bouillon which is used by many VLCDers and is allowed on Lighter Life (altho I note not CD).
There was never any secret that it may encourage the drinker to want to eat conventional foods, and that is why there was a recommended daily limit at 1 glass a day, but then personally I find that it is the one thing that I honestly can enjoy consuming on this diet and as such it actually helps me NOT to cheat, as I saw it as an 'allowed' pleasure.
I am really quite concerned now about how I will deal with this being something that is not allowed, as I will feel like I am being naughty when I drink it, although going without is more likely to do harm than good in terms of sticking to the plan....
HELP???!! what to do?? xx
