A bowl of this stuff in the morning can keep you going all day. Part of the reason is all the fiber. It fills you up and lets your body absorb the oatmeal’s nutrients more slowly. That keeps your energy steady. It may even help you eat fewer calories over the course of the day.
The liquid helps fill your stomach but doesn’t add many calories because it’s usually made with a lot of water. Just be sure to go for a broth-based recipe, like vegetable soup or those made with chicken or beef broth. Cream-based soups have far more calories.
