Oh go on, I'll bite.
The official reason sugar free squash isn't allowed is because nearly every brand contains citric acid, and some say that citric acid interferes with ketosis. Note the 'some say' because the jury is officially out. And given the jury is officially out on whether ketosis is the thing that causes appetite suppression, you might wonder what the big deal is.
But I suspect there are other reasons. Some people react to artificial sweeteners as if they're sugar, so the body mounts an insulin response. When no sugar is actually forthcoming, the next thing that happens is that you get hungry. And we all know where that can lead.
So...
It's well worth stating right now that the absolute, sure-fire guaranteed way of making sure that the Cambridge Weightcare Plan works for you is to stick absolutely to the rules. So if you can, please do.
Some people can't hack cheating in any shape or form. If you're one of those people (and you'll probably know if you are), stick to the rules. If breaking one rule is likely to leave you feeling guilty, don't break that rule and risk going on a downward spiral into the fridge.
Now, you asked the question does anyone do this - drink sugar free squash? Well yes, I do. But I couldn't possibly comment on whether it affects my losses (and no one else should either) because honestly I don't know what I might have lost if I hadn't drunk the squash. Do I have losses every week so long as I stick to all the other rules? Mostly, yes. Do I know whether it might've been more if I hadn't drunk the squash? No. Maybe I'd have lost exactly the same number of pounds, maybe more. Maybe less.
In other words - yes, I'm getting to the point - drink sugar free squash at your own risk.
