Attention, Oatmeal Lovers: Here's Why You're Hangry at 10 a.m. (How To Stop an Oat-Induced Blood Sugar Spike) (2024)

Have you ever wondered why you felt hungry — even hangry — just a few hours after eating a bowl of oatmeal? I certainly have. I love a warm bowl of oats with maple syrup and a splash of milk in the a.m., and always thought it was a relatively healthy breakfast. However, I've never understood why I felt tired or why my stomach would grumble just one or two hours later. Oats have fiber and protein, right? Shouldn't those nutrients make me feel energized and satiated?

"Oatmeal, by itself, could cause a spike in blood sugar depending on the type you choose and the quantity you eat at a sitting," says Michelle Rauch, RD at The Actors Fund assisted living facility. Below, Rauch explains the details and how to "dress up" your oats so you don't lose all your energy midday.

Why a Good Thing Goes Bad

Before you cut oatmeal out of your mornings completely, know that it can still be part of a well-balanced, satiating breakfast. "While oatmeal is high in carbohydrates, it is considered a 'complex carbohydrate,'" says Rauch. "Meaning: It also a good source of soluble fiber (including Beta-Glucan). Beta-Glucan has been long studied for its positive association with blood sugar, insulin response, and other cardiovascular benefits such as lowering cholesterol levels. The soluble fiber passes through the GI tract undigested, therefore slowing down the absorption of sugar and helping you avoid spikes in blood glucose levels."

Still, oats by themselves aren't the best solution. Complex carbs are still carbs, and they can lead to a blood sugar spike if you don't balance them out with other macronutrients. (Think protein and fat.) Plus, certain oat products, like instant oats, contain less fiber and protein than other varieties, and may contribute to an even greater sugar spike.

What's more, adding sweet stuff to your oats (I'm guilty!) is probably the worst thing you can do if you want to maintain even blood sugar levels. "I caution against adding certain toppings to your oatmeal, as you could turn a healthy breakfast into a calorie and sugar bomb," says Rauch. "Jam and maple syrup have the potential to cancel out the [good]. And despite its touted health benefits, honey is high in sugar — it has 17 grams in just one tablespoon.

"Do not assume that jam is mostly fruit and therefore healthy, either. Jams contain high amounts of added sugar and some even contain high fructose corn syrup. One tablespoon of Smuckers Strawberry Jam contains 12 grams of sugar, 9 grams of which is added."

As I mourn the homemade apricot jam and strawberry preserves in my fridge, I can't help but wonder if oatmeal can really be tasty with less sugary toppings. However, it's definitely worth a shot — and Rauch was determined to show me a few recipes to change my mind. Find them below.

Can't let go of your sugary syrups or jams? Here's what Rauch recommends you should also add to avoid that hangry feeling an hour later:

  • A scoop of plain protein powder.

  • ½cup skim milk or high-protein milk, such as Fairlife.

  • One tablespoon of chia, hemp, or flax seeds, which don't impart much flavor, for extra protein, fiber, and fat.

  • One tablespoon of a nut butter, preferably one with no added sugar or salt, for extra protein and fat.

Here's to keeping the hangry at bay.
