You'll feel full thanks to fiber.

If you're looking for a boost of fiber in the morning, oatmeal is a great place to start. Given that fiber helps you to lose weight, eating a 1/2 cup of old-fashioned oats gives you 4 grams of dietary fiber! Plus, eating foods high in fiber helps with your overall digestion and satiety levels, which means a bowl of oatmeal will leave you feeling full.

You can even increase the fiber in your bowl by adding 1/4 cup of pumpkin puree (2 grams of dietary fiber), 2 teaspoons of chia seeds (2 grams) and 1/2 cup of raspberries (4 grams). That boosts your bowl to 12 grams of fiber for one breakfast.

You won't be consuming a ton of sugar.

Unless, of course, you're consuming one of these packets of unhealthiest oatmeals. Many of the instant oatmeals you find on grocery shelves are packed with sugar, but you can easily avoid it by making your own bowl from scratch. Cook 1/2 cup of oats with 1 cup of unsweetened almond milk, and instead of adding brown sugar, 1 teaspoon of maple syrup will do. That brings your bowl of oatmeal down to just 5 grams of sugar! Even if you add in extra fruit on top, the sugar count will still be lower than some of those instant oatmeals—and a lot more satiating.
