Susie - I would agree with Harpar in her summary that it's a balancing act. I think it's fair to say that the key for most of us has been to reduce our carb intake. How we individually make up the balance of the calories we need in order to function healthily; whether that be to lose or maintain weight, is a matter of personal choice and lifestyle need.
Personally, I couldn't do the HIGH fat bit either. The prospect of bullet-proof coffee or adding fat to everything, just didn't do it for me. I'm fortunate. My body could metabolise those things, but it didn't appeal, and didn't feel like a way of eating that would fit with our household way of life. So, I've experimented and found my own way. Again, I am fortunate that I have always been able to eat some of the carbs others find challenging. I have been able to continue with my jumbo rolled oats, with a little added bran (ahem), and skimmed milk, for breakfast. In a "proper" LCHF world, I would give that up, but I don't have to and as my numbers are fine on it, I won't.
In my observation of you Susie, I observed initially resistance to almost any change; which is where we almost all start, then embracing the LCHF concept to an extent you weren't eating enough, and were constantly hungry? Then you added a bit more fat, and weight loss stalled?
The only thing I will say is, don't throw the baby out with the bath water. Tweak around the edges. Try adding or removing things as you go. Your bloods have improved, although I think you'd agree the numbers could do with being a bit lower still, but that should come. I eat lots of the stuff on the Med diet, but not all of it. I think Douglas suggested looking at a number of diabetic friendly ways of eating; LCHF, Med Diet, Low GI and even calorie controlled by reducing carbs, and highlight what you like in each of them, and see if it's possible to build a plan from there.
You've shown you want to make a difference; it's now just sticking with it, accepting that things don't always go according to Plan A, or B for that matter.
I know you cook for the family. Are you all eating the same things? What sort of feedback do you get from them?
It's not easy. As I've said a million times; if it was, we wouldn't all be here, feeling our ways forward into the next phases of our lives.
