Well, it was a fascinating national holiday/new guests in the country experience for me, when it comes to being a Low Carb Healthy Fat (LCHF) household, and sharing food and drink. And definitely, it turned out, when it comes to talking all that we discussed above with a newish person (friend of a friend).
As I mentioned above, the system I have done in the past ten years has worked well - explain the LCHF household thing, my health and T2D thing, tell folks to bring their own snacks, and what they like to drink, and explain what I will cook and provide for, and say we will decide together on the rest.
Usually folks bring lots of snacks and sweet drinks, and I don't have anyone going through sugar withdrawal in the house

. Which is good! (four days and three nights is enough for some withdrawal I believe).
My galpal doesn't eat added sugar, but my guess is her friend does (the norm after all), so she felt compelled to go along with the no added sugar ride. Ouch!
And, yeah, there was a lot of confusion from both my guests, still, about the difference between low carb and low calorie.
My new guest told me I shouldn't be drinking alcohol with my T2 (goodness gracious!!!), so I explained very patiently the difference between energy from alcohol and energy from carbs. (Of course I drink very low or zero carb alcoholic bevvies.)
I explained the diet-heart hypothesis and why I thought it was wrong when the new guest showed images of her slim 84 year old friend's hardened artery medical-imaging, when we alone together at a cafe, as evidence of the error of my eating ways. (Again - I would find it hard to make this up!). I told her alas, I would be very lucky indeed to get to 84, hardened arteries or nae. But that didn't stop her. I told her it was actually my kidneys I most had to watch out for, as I did not have blood pressure or CVD issues, touch wood, yet at least, due to my previous emphasis on exercise before disability, and still keeping up with strength resistance training, and boy did her eyes glaze over! (I'm not surprised! Who cares about details like that except me and my loved ones?)
I also discussed heart foundation funding when she also texted me what the american heart foundation says about eating meat and saturated fat. (keep it lean message. Processed meat is cancer causing.) And I suggested she read what the WHO and scienfitic studies actually says about the evidence that meat eating is contrary to a healthy diet for our species. (As in thin on the ground!) (Also - re processed meat actually.)
Anyway. It was pretty full on.
I think she 'd gone into sugar withdrawal after three days for sure, and was in shock and p.o-ed about the whole LCHF thing, and finding out she was like all of us, and prone to being addicted to the stuff, and she hadn't known before.
I also think there was a bit of wanting the lowering carbs and raising protein and fats to be normal weighted message I was saying about myself to be wrong. Who wants to give up all those lovely yummy carbs? Unless metabolically sick. After all! I quite understand. She had a lot of body fat, particulalry on her belly, and was also being pretty mean about her fat sister, who, it turned out, has Type 2 too. Oh dear! (Risk factor for her of course, as risk is double the 'normal' population.) So she could be scared. And again, not wanting the old messaging about eating animal fat and still going strong, to be wrong.
And - my normal weighted body and food and drink was something to argue against? yes. Apparently. Oh dear! Not pleasant.
Don't we live in interesting times?! Re metabolic ill/health and maintaining normal weight, and food and drink....
