How exactly does insulin resistance work, at a cellular or molecular level? What exactly causes it? (I’ve already looked it up on Wikipedia and googled it, so don’t you dare tell me to do that)
There’s some debate on this, and the answer probably varies: fewer receptors, receptors variants that don’t work as well, insulin variants that don’t connect as well, processes getting in between production and connection, etc.
Oh, so, the cause is not clearly known then.
