I'm also insulin resistant, but very low-carb (like Atkins Induction) always made me very ill - and it didn't get better or go away after two weeks as Atkins promises, instead it would just get worse to the point that I would actually pass out (so I was convinced that low-carb was not only unhealthy but possibly dangerous).
Then about seven years ago, my doctor recommended low-carb for my insulin resistance but warned not to reduce carbs too low (but admitted he didn't know what was too-low).
As a result I started (skeptically) experimenting, and discovered my best carb level - low, but not too low (I use an exchange plan with a carb level of about 100 to 125 grams of carbs).
Too low and I get sick. Too high carb and I feel constantly starved.
