Yes, in a nutshell there are two reasons not to skip meals. First of all, diabetic or not, when you skip meals, your body goes into starvation mode and the next time you eat, instead of using your food for fuel, your body stores it as fat. This is why starvation diets don't work.

Second, if you are diabetic, when you don't eat your liver will still produce glycogen until the glycogen stores are used up. If it gets bad enough your body will start breaking down fats for energy leaving behind acidic remnants called ketones. This will land you in the hospital with something called DKA-diabetic ketoacidosis. Trust me, you don't want it.
