Do you ever allow yourself an occasional treat? wine, whisky, choclate maybe some rice or bread?
I was about to type that I drink wine and whisky all the time - it isn't strictly true. I have however pretty much stopped drinking beer other than Salute zero carb.
Whisky is zero carb (as are all spirits) - it's certain mixers that would cause a carb problem. Wine (red) you can expect in the region of 20g carb a bottle, so a glass or two when I've had next to no carbs from other sources isn't a problem in this context. Neither therefore have any impact on my low carb pattern.
I have never been a chocolate eater so it wouldn't be a treat for me. I very occasionally will have some bread but only if it's worth it - the last time was on holiday in Italy September 2022, with a lunch in Greve. Had pasta at the same time. Yes, right off the wagon for that meal. The pasta was going to blow my glucose anyway, so bread was neither here nor there. Took me out of ketosis for three days and +2 hr post-meal reading went to 8.6.
I set myself my treat day well in advance - so I will again go off the wagon once or twice on holiday in late June, and we have a planned special event meal out in May where I will still be carb conscious but not to my usual degree. The real problem with the "treat" thinking to my mind is the temptation to treat yourself more and more often - a bad day, some good news, a day with a "Y" in it - it can creep up.
