Are Quest Bars Keto?

Are quest bars keto? Yes, sort of

Quest bars are protein bars, and protein bars are simply candy bars with more protein and a great marketing strategy. While Quest products replace sugar with oligosaccharides - sugar alcohols made from fermented fruit peels - there are still a lot of problematic and high-carb things going on here. You can fit them into your keto diet, but there are better alternatives and you need to be selective about how often and when you eat Quest bars on keto.

Keto rating: Okay

Quest bars are flavored with natural ingredients and oligosaccharides are reasonable in small quantities on keto, but the bars are filled out with a lot of fiber. Most of this is in the form of prebiotic corn starch fiber, which is both good and bad. Indigestible fiber is great for your gut microbiome, but corn and wheat products are sketchy at best on keto. Our bodies don't react well to them and our gut bacteria like fiber from non-starchy vegetables best.

Still, in a pinch, you can sneak a Quest bar in here and there and still maintain ketosis. Let's take an in-depth look at Quest bars on keto.

Examining Quest bars for keto dieters

Quest bars come in a huge range of flavors now - just about 8 years ago when the company started, they only had a few and while they were fine, they were pretty basic. The bars themselves are very chewy, though that has improved as well in the last 8 years. With the improved texture came a variety of flavor options, including:

  • Cinnamon Roll
  • Vanilla Almond
  • Blueberry Muffin
  • Mocha
  • Double Chocolate Chip
  • Cookie Dough
  • Birthday Cake
  • Peanut Butter Fudge
  • Fudge Brownie

There are plenty more than that and they release seasonal ones as well, like Pumpkin Pie. But with all these flavors, are they really keto-friendly? Most Quest bars boast around 25 total carbs, and more than half are usually from fiber. After that, there are the sugar alcohols, which make up around half of the remaining total carbs, leaving around 4-5 net carbs per bar.

Understanding "low carb" versus "keto"

While many keto adherents advocate a very strict policy of no additives, no wheat or corn, and often no sugar alcohols, this doesn't necessarily mean these things aren't "keto". Truth be told, ketosis is a state of your metabolism, caused by a low enough dietary carbohydrate intake. You could, through fasting and other carb restriction, probably enter ketosis even if you were eating a Snickers bar every day.

Low carb is different, seeking to keep your carb intake under 50-100g a day. This also has health benefits including weight loss, but is less restrictive, although the speed of weight loss is slower and the health benefits are lessened. The point is that Quest bars fit both keto and low carb lifestyles, if they fit into your macros, but you need to take care when using them with an intention of maintaining ketosis.

One good way to see if they fit into your diet is to allow yourself to eat them and see if your weight loss stalls. If so, they probably aren't for you.

Quest bars for the keto diet

There are currently 19 flavors of Quest bars, along with Hero bars (which are more like candy bars), and snack bars which are more nut-based. Let's look at a few and get a feel for their nutritional facts.

Quest bars for keto are okay, in moderation

While Quest bars are readily available - you can find them at most Walgreens and even gas stations - they're not something you should eat daily. If they don't interfere with your weight loss, there are certainly worse things you could eat, but for keto, there are better bars. Whole foods are always going to be the best option, but in a pinch, Quest bars are delicious, and if they fit your macros, can be a useful tool to keep you on track with your keto weight loss goals.
