There is certainly no need for you to lecture me on the role of insulin in metabolism, though I suppose it isn't necessary. 😬
By the way, you might want to pick up a physiology textbook and brush up on your understanding of basal metabolic rate.
I would assume that something described as "poor" is simply something that isn't functioning at an optimal level, rather than being perfectly fine. Now, perhaps you happen to be a medical doctor or hold some sort of professional credential, but I must confess that such details aren't particularly pressing to me right now. I have been dedicated to bodybuilding for about five years—just to clarify, I am strictly natural—and I actually dealt with the exact issue mentioned in this thread because, by nature, I am a quintessential ectomorph. Fortunately, I managed to sort it out; I am currently 6 feet tall, weighing 194 pounds with 8% body fat. That seems like a significant improvement over my previous state of 6 feet and 145 pounds, wouldn't you agree?!
To be honest, I have never felt much of a need to dive into the granular mechanics of how insulin works; my interest has always been more pragmatic, focusing on what works and what doesn't in a practical sense. It seems I have learned those lessons quite effectively, judging by the progress I see in the mirror. Furthermore, almost everyone I have ever consulted for advice used the specific phrase "poor insulin sensitivity," and one can find that exact terminology used frequently across numerous American bodybuilding forums and websites. So, I find myself wondering if everyone in the fitness community is somehow mistaken, or if perhaps you possess a more nuanced explanation that I am missing. If it isn't too much trouble, I would certainly welcome your insight.
