I have been on the Atkins diet, on and off for a long time.
I have now found Dr Fung's website as well as Dr Rosedale's website.
It was on Dr Fung's website that I found out that insulin resistance can be reversed. Dr Fung mentions that very established insulin resistance will take some time. However, he does not elaborate on this.

Although the Atkins diet has been successful at reducing my weight, over time, it has always returned (due feasting too often). My insulin resistance has only increased over this time. Now I am following Dr Fung's recommendation regarding intermittent fasting in my attempt to reverse my insulin resistance.

So, I actually have 2 questions:
1. How do I monitor my progress towards reversal?
2. How long will it take from anyone's experience?
Thanks
