Are Pure 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 these kinds of protein bars 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: D-

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:


ChocZero Macro Nutrient Ratio:

Label Net Carbs:
9g of labeled net carbs, 2g of which is sugar.

Estimated Net Carbs: (My estimation based on the caloric values and glycemic index of ingredients)
15g of estimated net carbohydrates per bar. 2g sugar, 7g regular label carbs, and 5g (rounded up from 4.5) from Maltitol.

20 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.

Pure Protein Bar Keto Conclusion:

I still haven’t found a ketogenic friendly "protein" bar and Pure Protein bars are no exception. Just like the others, they’re low in fat, high in protein, and deceptively high in carbohydrates which leave me unsatisfied and craving more. I also don’t like to have sweet foods around that will kick me out of ketosis if I overeat them even just a bit like these protein bars would.

If you’re like me your interest in protein bars is not to get extra protein, but a convenient sweet treat that won’t kick you out of ketosis. I personally don’t eat or recommend protein bars anymore and instead get my sweet fix with high fat, low protein, and low carbohydrate treats like Keto BarsChocoperfection, and Keto Kookies.

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.
