Are Quest Beyond Cereal Protein Bars Ketogenic Friendly?

At the time of writing this post, I’ve been on the ketogenic diet for over four years and logged over 200 blood ketone tests in an effort to estimate the effects of food and ingredients on my ketosis, including those in Quest Beyond Cereal protein bars.

I think ketogenic dieters naturally gravitate towards protein bars like these looking for a convenient sweet treat that won’t kick them out of ketosis but are protein bars the right place to look? In this post, I’ll evaluate Quest Beyond Cereal protein bars, give them a ketogenic compatibility grade, and recommend a more ketogenic friendly alternative.


Ketogenic Compatibility Grade: F

Savage Fuel Ketogenic Compatibility Grades:

  • A: Completely compatible, positive or no impact on ketosis.
  • B: Highly compatible, but don't go too crazy.
  • C: Moderately compatible, be mindful and limit intelligently.
  • D: Barely compatible, detrimental to ketosis and not recommended.
  • F: Not compatible, avoid or kiss your ketosis goodbye.

Grade Factors:


Quest Beyond Cereal Protein Bar Macro Nutrient Ratio:

Label Net Carbs:
10g of labeled net carbs, 8g of which is sugar.

Estimated Net Carbs: (My estimation based on the caloric values and glycemic index of ingredients)
14g of estimated net carbohydrates per bar. 8g sugar, 2g regular label carbs, and 4g (rounded up from 3.5g) from soluble corn fiber. (I estimate half of the carbohydrates of soluble corn fiber as net carbs because there it’s very difficult to find any glycemic or caloric information on it.)

12 grams of protein for your body to convert into glucose via gluconeogenesis. Too much protein can prevent ketosis.

Difficult not to overeat due to the sweetness triggering cravings, good taste, and elevated blood sugar from the protein and net carbs causing hunger. Also unsatisfying on a ketogenic diet due to the lack of fat.

Quest Beyond Cereal Protein Bars Keto Conclusion:

My ketogenic breakfast of choice is black coffee and body fat so I can’t imagine having one of these instead. Quest Beyond Cereal protein bars are just like the others except they have less protein and more sugar. I still don’t recommend any protein bars because I don’t think they’re a good fit for a ketogenic diet.

My previous interest in protein bars was to find a convenient sweet treat that wouldn’t negatively impact my ketosis. After years of ketogenic experience, I’ve decided to cut them out entirely as they all leave me unsatisfied and craving more. Thankfully there are other options that are tastier, satisfying, and much more ketogenic friendly.

My Favorite Ketogenic Friendly Dessert


ChocoPerfection blew me away the first time I tried it, the taste and texture were so much better than any other low carb chocolate I’d tried before. I thought it might be too good to be true so I tested my blood ketones one day then ate four bars of it, at the same time the next day my blood ketone reading was even higher than the previous day, I was sold.

I give ChocoPerfection a A ketogenic compatibility grade because of it’s low net carbs (2g per 50g bar), high fat, low protein, zero glycemic index sweeteners, and no mystery “fiber”. The only two downsides of ChocoPerfection are that it is expensive and if you really pig out you’ll most likely become the eye of a fart storm (a side effect of Erythritol and Inulin), both are prices I’m usually willing to pay.

They have a lot of great flavors too, dark and dark mint are my favorites and Raspberry is the only flavor I don’t like. The dark mint with a handful of macadamia nuts tastes just like thin mint cookies. You get the classic mint chocolate flavor with the salty and crunchy macadamia nuts, it’s my favorite ultra low carb dessert.

If you’re interested in trying some I’d recommend getting the variety pack and a pack of the dark chocolate so you can try all their flavors and still have more of the dark which you’re going to like anyways. They also have chocolate chips if you’re into baking and free shipping in the United States.
