Being resistant to insulin means that when you consume too many carbs they are more likely to end up as body fat rather than energy for the cells to feed on

So the solution to both that and your weight problem is simple = Eat Less Carbs

Then their is less need to for insulin which you are resistant to and you won't have "leftovers" to get turned into even more body fat

Does that mean you need to "count carbs"?
