You’ve probably heard of the glycemic index (GI) before but might be unsure what those numbers mean.
The GI rating of foods tells you how quickly a carbohydrate will raise your blood sugar levels, with 0 having no impact and 100 having a significant impact.
Overall, research on the glycemic index is mixed.
Experts recommend focusing on the overall balance of your eating pattern and considering the GI a tool that may guide you in choosing high-quality carbohydrates.
Starting your day with a low-glycemic breakfast may help regulate your blood sugar levels and keep you full all morning.

Top 10 Low Glycemic Breakfast Ideas
Start your day with one of these low-GI breakfast ideas packed with high-fiber foods like oats, eggs, fruits, and veggies.
1. Steel-Cut Oatmeal with Blueberries
Enjoy this blood sugar-friendly breakfast by cooking steel-cut oats in milk and topping with blueberries.
Sprinkle with walnuts or stir in almond butter for added protein.
Though steel-cut oats have the lowest glycemic index, old-fashioned oats are only a few points higher on the scale, making them an acceptable substitution.
However, keep in mind that quick-cooking oats have a high glycemic index.
2. Yogurt Parfait With Bran Flakes And Berries
For a no-heat breakfast you can make in advance, try yogurt parfaits.
Layer unsweetened Greek yogurt with mixed berries and top with bran flakes for a crunch.
You can also add chopped nuts.
To save time, try using frozen berries–simply make up your parfait the night before so the fruit has time to defrost.
Wait until the morning to add crunchy toppings.
3. Eggs With Whole Grain Toast
A classic breakfast option, eggs have a glycemic index of zero and provide a rich source of protein.
Cook your eggs in the way you prefer–scrambled, hard-boiled, or fried.
To balance the meal, serve with low-glycemic sides like whole wheat toast and an orange.

4. Breakfast Burrito
To make a blood sugar-friendly breakfast burrito, start with a whole wheat tortilla.
Then add low-glycemic ingredients such as:
- Eggs or scrambled tofu.
- Beans (black beans, pinto beans, etc.)
- Veggies (spinach, bell peppers, mushrooms, onions, etc.)
- Avocado.
- Salsa.
- Cheese.
Try making a batch of burrito filling at the beginning of the week for easy morning assembly.
5. Green Smoothie
A smoothie can be a great way to get a serving of fruits and vegetables first thing in the morning.
Start with a liquid base of milk, water, or plant-based milk.
Add a protein source, such as protein powder or nut butter.
Next, add your fruits and veggies.
Most fresh fruits and vegetables are low on the glycemic index scale because of their fiber content.
Examples include:
- Cherries.
- Leafy greens.
- Blackberries.
- Blueberries.
- Strawberries.
- Avocado.

6. Peanut Butter Toast With Apple
For a quick breakfast, try peanut butter on whole wheat toast.
Top with thinly sliced apples and a sprinkle of cinnamon for some natural sweetness and flavor.
Be sure to look for all-natural peanut butter which does not contain added sugars, oils, and fats.
If you prefer, you can add banana slices instead.
Bananas have a higher glycemic index than apples but are still considered a low-GI food.
7. Tofu Scramble With Veggies
Tofu is a great low-glycemic protein alternative for breakfast if you don't like eggs.
Make a “tofu scramble” by crumbling a block of tofu and sauteeing it with seasonings like garlic powder, salt, and nutritional yeast.
You can add other low-glycemic ingredients, such as spinach, mushrooms, pinto beans, and avocado, to balance this meal.
Serve with a side of whole wheat toast or wrap in a whole grain tortilla.
8. Baked Oatmeal
Baked oatmeal is a delicious low-glycemic breakfast you can prepare in advance.
Mix all the ingredients together, pour into a baking dish, and bake until firm.
The primary ingredients to include are:
- Old-fashioned oats.
- Milk.
- Egg or ground flax seeds.
- Baking powder.
- Fruit, such as berries or apples.
- Nuts or nut butter.
- Spices, like cinnamon, nutmeg, or pumpkin spice.
9. Egg Bites
Simply crack an egg into each compartment of a muffin tin, mix in veggies and cheese, and bake!
Egg bites are a great low-glycemic index breakfast and make a complete meal when paired with a high-fiber carbohydrate like whole wheat toast.
You can also add cooked quinoa to your egg bites before baking for an all-in-one balanced breakfast.
10. Black Bean Breakfast Tacos
Try breakfast tacos for a low-prep and blood sugar-friendly meal.
Add sautéed black beans, zucchini, mushrooms, and onions to corn tortillas.
Top with salsa, avocado, and cilantro.
If you prefer a higher protein breakfast, you can add options like:
- Lean ground beef.
- Shredded chicken.
- Scrambled eggs or tofu.
What Does Low-Glycemic Mean?
The glycemic index (GI) is a scale that measures how quickly different carbohydrates will impact your blood sugar levels.
Each food is given a rating from zero to 100:
- Low GI: 55 or less.
- Moderate GI: 56-69.
- High GI: 70 or higher.
High-GI foods are quickly digested and can make blood sugar levels increase rapidly.
These foods are usually low in fiber, like white bread.
Low-GI foods digest much slower and gradually enter the bloodstream, which decreases their impact on blood glucose levels.
High-fiber foods like whole grains, beans, and most fruits have a low glycemic index.
Foods that do not contain any carbohydrates have a glycemic index of zero, such as eggs and meat.
Glycemic Load
Glycemic load (GL) is a separate measurement that may be helpful to consider when making food choices.
While the glycemic index represents how quickly a food will impact blood sugar levels, the glycemic load notes how much a food will raise blood sugar levels.
Though the glycemic index and glycemic load can be helpful tools, experts recommend considering other factors, too, like the balance of macronutrients in your meal and portion sizes.
Benefits of Low Glycemic Breakfast Foods
Typical American breakfast foods, from donuts to white bread to bagels, are high on the glycemic index scale.
Making swaps to reduce the glycemic index and load of your morning meal can support healthy blood sugar levels and help you meet your daily fiber needs.
Research shows that eating a low-glycemic breakfast meal results in lower blood sugar levels 1-2 hours after eating compared to a high-GI breakfast.
Additionally, a small study from 2015 found that consuming a low-GI breakfast and afternoon snack reduces 24-hour blood sugar levels significantly as well as lowering calorie intake at subsequent meals.
Because low-glycemic foods tend to be high in fiber, a low-GI breakfast contains over double the fiber of a high-GI meal.
This can help you start the day with a meal that keeps you full longer.
Tips for Incorporating Low-Glycemic Breakfast Foods into Your Routine
To get started with a low glycemic diet, make higher fiber swaps for typical breakfast foods.
For example, you can substitute:
- Whole grain bread instead of white bread.
- Steel cut or old-fashioned oats instead of quick oats.
- A whole grain bagel instead of a white bagel.
- Bran cereal instead of sugary cereal.
In general, try to emphasize whole foods for breakfast.
Preparing your morning meal at home is the best way to accomplish this.
If time is a barrier, try low-GI breakfast recipes that work well for meal prep, such as:
- Overnight oats.
- Egg bites.
- Baked oatmeal.
- Freezer breakfast burritos.

Who Should Monitor Glycemic Index?
Paying attention to the glycemic index of the foods you eat can be helpful if you have diabetes.
Research shows that focusing on low-GI, high-fiber meals is a beneficial strategy for blood sugar management.
Other metabolic conditions may also benefit from low glycemic index meals, such as:
- Polycystic ovarian syndrome (PCOS).
- Overweight or obesity.
- Heart disease.
However, many studies are conflicting, and more research is needed to fully understand the role of glycemic index in these conditions.
Remember that glycemic index is only one piece of the puzzle when it comes to a nutritious diet.
Avoid an all-or-nothing mindset (“I can only eat low-GI foods”) and include all the macronutrients for a balanced breakfast.
Takeaway
The glycemic index (GI) measures how quickly a given food will increase your blood sugar levels.
Though GI is only one part of balanced nutrition, it can be a helpful way to choose foods that are blood-sugar friendly if you have diabetes or another metabolic condition.
Start your day with a low glycemic breakfast by including ingredients like steel-cut oats, berries, apples, whole grain bread, eggs, tofu, and beans.
