To be honest, I think, in the real world, there will be a fair few inadvertantly carb cycling. There will be many who low carb quite well, but either have a treat each weekend, say, whether it's Sunday lunch, Friday takeaway or whatever, or who just give in to their own variant of temptation from time to time, but then revert to whichever path they find best.
As ever, I'm not keen on labels, then forensic label dissections, because few of us live our lives to a labelled level of perfection.
Those who manage their condition by their mainly LC eating, with the odd meandering, and still achieve A1cs to their, and their hralth care team's satisfaction, then great. It's not my or anyone else's place to judge them, or they me.for that matter.
