i have oatmeal for breakfast at least a couple times a week. I also like to make ahead of time baked oatmeal squares (baked with egg/egg whites, fruit, and some pecans) for a fast n healthy on the go breakfast or snack. they freeze well and you can just microwave them for 30 secs to reheat.
Many people associate oatmeal with being a weight loss food because it is a low glycemic food.
here's a nice little informative page about the glycemic index and how eating foods low on the glycemic scale contribute to keeping blood sugar levels stable and feeling full:
