Hello Susie and welcome.
Well done on your weight loss so far. If you want to control those blood sugars you will have to bite the bullet and cut down on those carbs I'm afraid. Carbs = Sugar as you seem to already know. Cutting down carbs means you do have to increase your fats and/or protein, but there is no need to go overboard with high fat, just don't actively avoid it. If you have a read about low carb diets you will see that many of us are actually lowering our cholesterol by eating this way.
