You are probably going to need to raise your protein consumption and replace the carbs like cereal with protein.
For most meals 4-6 oz of meat would work.

Something to think about is that anything low fat has elevated levels of sugar to compensate for the lack of flavor. So find yourself some full fat salad dressing, low in sugar.(read labels)

Vegetables have some carbs too but Nothing Like noodles, rice, bread, cereal, crackers etc.. which turns into sugar when you eat it.

Focus your meals around some pork chops, a steak, a 3-4 pieces of chicken, sausage 100% meat no added sugar, eggs, bacon, 4 oz ground beef or burger patty with your low carb vegetables. (don't be afraid to eat the protein you need to fill-up)

Cook them with butter, coconut oil. olive oil and no added sauces with sugar in them.
