Low blood sugar is ruining my diet

Doctor told me I had no diabetes, just insulin resistance. But I'm getting sugar drops between meals. I've cut out sugar, eating out, carbs blah blah, and I've been fasting 16/8. I've lost 3kgs in the last 2 weeks. Working out, taking walks in the evenings. But getting sugar drops between meals is crushing me because unless I take any type of carbs or sugar right away it doesn't get better. Is this normal with insulin resistance? I'm all new to this.
