Breakfast cereals are a popular, convenient meal or snack for adults and kids alike.

Yet, many cereals are far from nutritious, as they’re not only low in protein and fiber but also high in added sugar.

Notably, high added sugar intake is linked to an increased risk of several chronic illnesses, including heart disease, obesity, and non-alcoholic fatty liver disease (1, 2, 3, 4).

Additionally, eating high sugar cereals can lead to increased blood sugar levels in people with diabetes. Over time, these elevated levels may allow the disease to progress, as well as increase your risk of complications like heart disease (5, 6, 7).

Nonetheless, numerous sugar-free breakfast cereals are available. Some are simply unsweetened, while others may contain sugar substitutes like stevia, erythritol, or monk fruit.

They may be good options for the low carb, high fat keto diet — though it’s important to note that you should keep a careful eye on the carb count, as some sugar-free cereals are still high in carbs.

Healthcare Website evaluated sugar-free cereals based on the following criteria:

  • taste
  • ingredient quality
  • the presence of artificial additives and preservatives
  • nutrient content
  • their suitability for diabetes or the keto diet

Here are the 10 best sugar-free breakfast cereals.

Certified by the Whole Grain Council and non-GMO verified, Barbara’s Shredded Wheat is the best whole wheat option thanks to its simple ingredient list and high fiber content.

Regular intake of whole grains is associated with a reduced risk of several diseases, including heart disease, stroke, type 2 diabetes, obesity, and certain cancers like colorectal cancer (13, 14, 15, 16).

HighKey makes keto-friendly breakfast cereals, snacks, and baking mixes.

The keto diet is a very low carb, high fat eating pattern originally developed to treat seizures in children. It causes the body to burn fat in the form of ketones.

The standard version of this diet limits carbs to 20–50 grams per day to sustain ketosis, a metabolic state in which your body burns fat for fuel instead of carbs (18).

HighKey Protein cereal comes in four flavors — cinnamon, cocoa, frosted, and fruity. Each product contains less than 1 gram of sugar per serving, has a limited ingredient list, and is sweetened with natural sweeteners like erythritol, monk fruit extract, and allulose syrup.

Allulose is a very low calorie, low carb sugar substitute that’s found naturally in a few fruits and whole grains but often manufactured in a lab. It’s generally recognized as safe and isn’t linked to any serious side effects (19, 20, 21, 22).

HighKey also offers some of the highest protein cereals on the market. Because their protein comes from milk protein isolate, their products aren’t dairy-free or vegan. However, they’re gluten- and grain-free.

One cup (56 grams) provides (23):

  • Calories: 180
  • Fat: 10 grams
    • Saturated fat: 8–10 grams
  • Carbs: 11 grams
  • Fiber: 3 grams
  • Sugar: less than 1 gram
  • Erythritol: 12 grams
  • Allulose syrup: 4 grams

When shopping for sugar-free cereal, look for products with short ingredient lists that contain mostly whole foods and are free of artificial colors, flavors, and preservatives.

To help you stay full for longer, try to choose a cereal with at least 3 grams of fiber and 4 grams of protein per 1-cup serving.

It’s also important to pay attention to the serving size, as you may find that you consume more than one serving in a typical meal.

Finally, if you have diabetes, remember that just because a cereal is sugar-free doesn’t mean that it’s also low in carbs. If you eat cereal with dairy or nondairy milk, both of which likewise contain carbs, make sure that the total carb count fits your allocations for a meal or snack.
