I probably jumped on your post unnecessarily. Apologies. If I see any talk asking about low
large versions of food I get twitchy.

Actually, your choice of single cream isn’t a low
large version of anything. It’s still a natural food which I think is the most important when it comes down to it.
Though I have to (respectfully!) disagree about the “science of calories”. If the science of calories worked, the ‘diet’ industry wouldn’t be thriving for decades. Keto isn’t just about eating lots of healthy fats and hardly any carbs to keep us full and not overeat. It’s about being in ketosis (or close enough) and your body using but not storing fats for energy instead of carbs. Because of this screwed up society obsessed with counting calories for eons, this is probably exactly why 90% of us are sitting in this thread right now. Through my experience of losing just over 100lb on atkins/keto the more I thought about calories and tried to keep count (because for decades that’s what we’ve been indoctrinated to do) the faster my weight loss slowed. And by slow I am meaning stalled for months. Towards the end of my journey when I had less to lose,
I had to eat way over the accepted ‘norm‘ of daily cals and the weight loss would kick back again. But that’s just my experience.
I’ll fully admit I haven’t read the ’rules’ of the latest fad keto diet (but read many other versions of it before ”keto” was the latest way to describe a low carb diet) and just stumbled across this thread as I have a stubborn low-ish amount of weight to lose but cannot eat dairy or nuts anymore so low carbing is much more difficult...hence the annoying weight gain. Or the gain could just be my hormones and screwed up thyroid in peri meno. Who knows? I actually have no clue what I weigh as I ditched the scales long ago because the fit of my clothes and my fitness is much more important than any number in my head dominating my life. The only numbers me and my doctor care about are my blood panels and BP. I did follow atkins and didn’t gorge on cream and cheese daily but easily ate way over 2000cals a day for years in the form of ‘healthy fats’ ie salad with avocado and eggs for breakfast, some kind of protein with a large plates of low carb vegetables for lunch and dinner and no restriction on added fats.
Anyway, I am babbling now. Thanks for the healthy and respectful chat about this! Happy to go private if you’d like to chat more so we don’t clog up this thread. Good luck with your journey!
