Think of it like a bathtub. The lower carb diet is like turning down the faucet to a trickle. Intense exercise is like pulling the plug from the drain. You have to create a glucose drain by emptying the muscles of their glycogen stores via intense exercise. That will make the muscle cells MORE insulin sensitive which reduces your insulin levels. It also means that any glucose (veggies and fruit) beyond brain needs is gobbled up by the muscles for glycogen storage in preparation for your next infrequent intense workout.
So while it's true that eating low-carb will lower your blood insulin levels, intense exercise will help lower them further.
