Hi Syb,
This is one of those things that we each have to make our own decision about. Obviously, having lost weight & feeling so much better as a result of this diet, none of us want to ruin all the work and pile the pounds back on. Like you, I like a nice sandwich (Tesco’s remaindered counter is one of my favourite haunts! Sad!!) – but rather than being my “what shall I stuff myself with tonight” option, it really is just an occasional treat. While I was only ever just an occasional potato/rice/pasta eater, I am not going to deny myself the occasional risotto (with proper rice), or roast potatoes (if I’m eating out), even a decent loaf of bread. Darn it, I still like highly processed sausages – Quorn ones are OK but they just don’t set my taste buds alight!
I’m not diabetic so I guess my health issues are slightly different to yours. I have recently tried reintroducing a few things I’ve cut out. I also was a bit lax about late night eating. And I didn’t do quite as much exercise. Guess, what: my weight loss stalled, even went up slightly. So very quickly I restricted things again and have now got rid of the excess. If I want to reach my target then I can’t relax things too much. So the moral of this tale is keep an eye on the scales, snugness of clothes, any medical readings you might be taking (but no need to get obsessive about it) and if you find you are gaining weight again you know exactly what you need to do to nip things in the bud.
Everything in moderation. A little restriction to keep things in check is much better than having to start from scratch again.
