Sampling and Reviewing 3 Low Carb “Keto” Cereals

I sampled, reviewed, and compared three different low carb cereals all in cinnamon flavors. Find out how each brand stood up to the test! 

If you are interested in a low carb diet or following a Keto diet, you might be super interested in trying out some low carb cereals. Especially is cereal is one food you are hesitant to give up.

But there’s a reason that I’ve never tried low carb cereal before, they cost a pretty penny. About $10 a box, and for a small box at that.

I’m going to share my thoughts on value, flavor, how filling they are, and more of three top brands of Low Carb cereal so I can save you the money on trying them all yourself!

I put to the test Diabetic Kitchen, High Key Protein Cereal, and Catalina Crunch all in their cinnamon varieties for a more across the board comparison.

My Experiences with Low Carb Cereal and the Keto Diet

As someone who has been following a low carb diet for years you may be surprised to find that I’ve never tried low carb cereal before! I very rarely eat cereal as it is, so I didn’t even notice taking it off the table to follow a Keto Diet.

But I know I’m not the norm. I know many if not most people love cereal. Or else there wouldn’t be an entire aisle in the grocery store filled with seemingly endless varieties.

Though I only follow a low carb diet now, I’ve also followed a strict Keto Diet twice before for about 6 weeks each time. You can read all about the first time I tried the Keto Diet and why I stopped it in the first place.

And learn more about when I gave a Ketogenic Diet a second try, how much better it went, and my results that time!

Both times I followed a STRICT carb count. I did not count net carbs, I counted ALL carbs. (Learn about how to count net carbs here.) Most people giving a Ketogenic Diet a try for weight loss only count their net carbohydrate intake, which gives you A LOT more leeway in what you eat. 

However, I was trying the Keto diet initially for medical purposes and thought a strict carbohydrate count (as most people following a medically recommended Ketogenic Diet would follow) would yield better results.

If I were to see any of the results I was hoping to at least.

Even though I didn’t follow a Ketogenic Diet long term, I still eat a low carb diet. Plus, my journey through Keto helped me craft some delicious recipes along the way.

Being that I have never sampled them before, it was fun to try out low carb cereals for the first time!

This post was inspired by the most in depth post I’ve come across that compares over a dozen different low carb cereals in depth! Including all different flavors and additional brands as well.

**I’m typing up my review here but there’s a video at the end in case you don’t want to read it!**


The Best Cinnamon Low Carb Cereal Reviews

Diabetic Kitchen’s Cinnamon Pecan Granola


The first cereal I received and sampled was Diabetic Kitchen’s Cinnamon Pecan Granola Cereal.

This cereal has only 3 grams of net carbs. In case you are not familiar with what “net carbs” refers to let me briefly explain:

You take the number of carbohydrates in a food and subtract a few things, namely the fiber.

This is what your body would truly process as carbohydrates and convert into glucose. MOST people following a Ketogenic or low carb diet count net carbs.

I was pleasantly surprised by this granola replacement. It’s absolutely loaded with nuts and seeds, a light cinnamon flavor, and is quite sweet with a distinct stevia flavor.

If you are craving something satisfying and sweet that tastes like fall in a bowl I would give this a try! I’m not a huge fan of sweetness so it was a bit much for me as a cereal.

But as a topping or a snack when craving something sweet, this granola is exactly what you need!

It actually has a really great blend of flavors. I think it makes an amazing snack to nibble on and the variety in the granola makes it reminiscent of a sweetened trail mix.

I wasn’t completely full after having 1 cup with almond milk, but pretty close.

  • Cost Per Box: $13.00 +
  • Size: 11 oz
  • Suggested Servings Per Container: 10 (at 1/3 cup)
  • Worth it? Yes, very expensive (all low carb cereals are), but a great snack or topping that tastes like fall.

High Key Protein Cereal

The second low carb cereal I sampled was High Key Protein Cereal in cinnamon with 0 net carbs.

This was my least favorite of the bunch. If you are a fan of puffed rice and super sweetness you might actually like these but I found them unsatisfying and the flavor was too much.

The bitter sweet flavor of pure stevia is absolutely overwhelming and being that they are reminiscent of puffed rice, 1 cup with almond milk did not nearly satiate me.

I would have to have multiple bowls to fill me up and at over $10 for an 8 oz box, I just don’t see this cereal as being worth it. I could easily eat half of the box in one sitting.

Even my kids didn’t like this cereal.

  • Cost Per Box: $11.47
  • Size: 8 oz
  • Suggested Servings Per Box: 8 (at 1/2 cup)
  • Worth it? I would say no way. Unless you love the taste of stevia or light puffed rice cereal.

Give High Key Cinnamon Protein Cereal a TRY NOW!


Catalina Crunch


The third and final low carb cereal I tried was Catalina Crunch in cinnamon toast.

This was actually my favorite of the three low carb cereals. I like healthy tasting and hearty cereals like Fiber One. This did the trick.

The cereal pieces are dense, and looked kind of like little cinnamon toasts.

Plus one cup with almond milk left me fully satiated!

If you are a light sugary cereal lover this will not be your favorite, as the texture is dense and unique. It is not your typical cereal texture.

However if you are like me and prefer cereals more like Fiber One, Quaker Oat Squares, and the like, you just might love this like I did!

  • Cost Per Box: $9.99+
  • Size: 9 oz..
  • Suggested Servings Per Box: 10 (at 3/8 cup)
  • Worth it? Yes, this cereal is super filling and my favorite. But if you don’t like dense hearty cereals probably not for you.

Give Catalina Crunch in Cinnamon Toast a TRY NOW!


Wrapping Up The Best Low Carb Cereals in Cinnamon

It was a pleasure to try all of these low carb cereals because they were all so distinctly different.

Very similar in price, very similar in serving size, but completely different textures and flavors.
