Sorry if this is a briefer response than I would like,
@No2D but it is a busy morning, and if I don't respond now, I may forget later!
My 5 month experiment wasn't really very organised. I gave up gluten in October last year, and spend several months feeling progressively better because of that. At the same time, I did months of intermittent fasting. The fast routine varied, but usually one evening meal a day, Mon-Fri with a coffee substitute and cream for breakfast. Weekends I would have a protein only breakfast, then an evening meal (also known as Warrior Fasting). I would calculate that there were approx 1000-1500 cals a day. And I only lost 2 pounds in 5 weeks of doing that strictly. The rest of the time I was more flexible, but still did IR regularly. That silly-small weight loss was a real bummer. I am obese, and my BMR would indicate that I was in calorie deficit by around 1000 calories a day for those 5 weeks. That was rather frustrating.
Then in the spring there was a thread on here about doing the DietDoctor menus (20g carbs a day, masses of fat), and I decided to try that. It was actually FAR more food than I could face on a daily basis. I just can't cope with 3 meals a day any more! lol. So I soon started skipping breakfast, easing up on some of the high fatness, and introducing more greenery. However, I stayed well under 20g carbs (what with skipping some meals), and the calories worked out anywhere from 1500-2500 a day. There is quite a lot of variation in the fat levels from meal to meal.
My weight fluctuated for the 3-4 months I was doing the DD strictly, but it stayed within the same 3 pounds either way, that I had been during my Warrior Fasting.
Then, more recently, I have been eating more carbs (since being gluten free, I have found my carb tolerance has risen a bit, so long as they are gluten free carbs). I am still usually under 60g carbs a day, often under 30g. But I have been eating to my appetite, and not bothering to monitor anything other than blood glucose. Anyway, one day I decided to tot up calories and it was absurdly low. I think 1150, and then only that high because I had eaten a blob of icecream on a whim.
but guess wot? Still the weight remains stuck in that same 3 pound range.
Through it all my exercise of dog walking has remained constant.
I may be the perfect living example of having a set point.
But I am DEEPLY RELUCTANT to reduce calories to Newcastle Diet levels. Been there. Did that in the 80s and 90s and I have no intention of doing it again and screwing up my metabolism further. Basically, I think that it was those diets which have led to my body being able to adjust its energy usage to precisely match the energy intake.
Somewhat annoying. But I would much rather be this weight whilst enjoying food and life, eating delicious low carb food in the quantities that appeal - than constantly stressing and worriting and counting every macro, in the desperate hope that I might shave off a pound. It just isn't worth it, in my humble opinion. Always accepting that everyone else's mileage will vary on that perspective. This is just such a long game, and I shudder when I think of the damage that yoyo dieting does to the body, over decades.
You asked about insulin resistance measuring, estimating and lowering.
The Big 3 ways I know to lower IR are, in order of effectiveness:
- avoiding carbs and intermittent fasting
- exercise (works very well, but has to be fairly strenious, done regularly, and only works for a few hours after each exercise session, with a long term downward trend if muscle and fitness levels improve)
- drugs like Metformin
Oh, and you may find this thread by BB interesting. I am finding it fascinating.

Sorry, got to dash.
