I hope this bumps the topic from 2015 because this is the biggest discovery I've ever made regarding my health issues, and curing many of them already. I only discovered Insulin Resistance (IR) through Youtube videos while trying to find "fixes" for my newly diagnosed T2 Diabetes. I found how to cut out the carbs (lower them) and eat more protein, and fats (YES, fats! Good healthy fats). I've lost 15 lbs the healthy way and it's taken me 5 months of being right on with my foods, but a bit lacking in my exercise. Usually only 2 times a week, for 30 minutes.
IR is something I am learning more about now, and realize I have probably had it for maybe, most of my life. I am 68 now. The doctors I've had over the years never once told me I was pre-diabetic, maybe because they never checked, and I've never been told I need an Insulin lab done. Conventional medicine does not usually call for that as far as I know. I believe Insulin Resistance is the beginning, and Type 2 Diabetes is one result of having it.
More later if anyone is interested.
