So, are Fiber One brownies keto? You may be surprised to find out the Fiber One bars are keto friendly, as long as you stick to the recommended serving amount!
What are Fiber One Brownies?
Fiber One Brownies are a low-carb, low-sugar, high-fiber alternative to classic brownies. They are fudgy and dense in texture and have a distinct chocolate flavor, same as normal brownie – but are sweetened primarily with sugar alcohols, which significantly brings down their carb and calorie content.
A Keto-Cap (aka A Keto Recap!)
If you’re new to keto and want a bit more information, check out our keto beginners guide.
As a quick summary, if you need it, the keto (also known as the ketogenic diet) is a low-carb, high-fat diet.
The whole concept of the keto diet is that your body transitions from burning glucose, in simple terms, sugars or carbohydrates, to burning fat as its primary fuel source.
For a keto diet, people will restrict their macros to eating;
- 70% of their calories from fat
- 25% from protein
- 5% from carbohydrates
Sticking to these macros for a period of time will put your body into a state of ketosis. Ketosis is when your body has transitioned from burning carbohydrates as its primary fuel source to burning fat for fuel. It is at this point that you will start to see and feel the benefits of the keto diet.
There are a lot of new terms and abbreviations that you may come across, sometimes it can feel like a new language that you need to learn. In order to help you out and keep you on the right track, we have created a keto terms and keto abbreviations guide, bookmark these to make your keto journey easier.
Some people can be put off the keto diet because of the side effects, however, these are only short-lived and the health benefits of keto far outweigh the side effects.
One of the main benefits which attract people to the keto diet is that it can cause significant reductions in insulin levels (by up to 75%) and blood sugar levels, which can be attractive to those that struggle with diabetes, amongst other health complaints.
What is the Nutritional Value of a Fiber One Brownie?
Fiber One Brownies can quickly become a danger to your keto diet if you overdo it. Here’s a comparison of nutritional value per 1 bar vs per 100g to paint a clear picture:
| Macros per 100g | Macros per 1 Bar (25g) |
| Carbs: 68 grams Protein: 8 grams Fat: 12 grams Fiber: 24 grams Sugar: 32 grams (24g from sugar alcohols) Calories: 280 | Carbs: 17 grams Protein: 2 grams Fat: 3 grams Fiber: 6 grams Sugar: 8 grams (6g from sugar alcohols) Calories: 70 |
How Many Net Carbs are There in Fiber One Brownies?
Fiber One Brownies net only 5g carbs per one 25g bar.
At first glance, this may seem confusing due to only 6g of fiber per 17g carbs, which would usually come to 6g net carbs. But with Fiber One Brownies we deduct an additional 6g of carbs due to them coming from sugar ALCOHOLS.
Not all (ex. maltitol), but many of the sugar alcohols are keto-friendly including the ones used in Fiber One brownies (primarily erythritol and sorbitol), so we can deduct them from the total carb amount along with fiber.
Are Fiber One Brownies Keto Friendly?
Yes, Fiber One Brownies are probably one of the most keto-friendly desserts out there but 5g net carbs per serving still aren’t very low, as we’re not talking about a full-fledged meal here/
The optimal keto diet means sticking to less than 20g net carbs per day, so if you want to enjoy a slice of Fiber One Brownie, do keep an eye on what you’re eating before it and try to keep net carbs per meal as low as possible.
Are there any non-Keto-friendly varieties of Fiber One Brownies?
Yes. While Fiber One is mostly known for its low-carb keto-friendly brownie line, they also offer a non-keto “sweet treats” line. This includes Supreme Brownie Triple Chocolate and Supreme Brownie Cookie Dough (both contain 17g net carbs per one 32g bar).
If you’re craving a brownie, Fiber One is a good option – just make sure to stick to the low-carb options. This won’t be hard, as they come in distinct blue boxes advertising 70 calories, 5g net carbs, and 2g sugar in a rather large script.
