Oatmeal is high in carbs, which is our body's preferred source of energy, but Freeman explained that it's made up of complex carbs, which are different than the simple carbs found in processed carbs like flour products. Complex carbs contain soluble fibre, which not only promotes satiety but also takes more time to digest, so you stay full for longer.
This makes oatmeal an excellent choice if you're trying to lose weight, especially if you add fruit to up the carbs and fibre even more. This means you can eat a bowl and feel satisfied all morning, so you won't feel the need to snack before lunch.
