Are QUEST Bars “Keto-Friendly”? [Hint: Only 2 Make the Cut]

The Quest Bars are probably one of the most popular bars among dieters and non-dieters worldwide.

They taste good, give a quick energy boost, and what's most important, you can buy them from everywhere. 

But are Quest Bars keto-friendly snacks?

Most snack bars taste like rubber and most likely knock you out of ketosis.

Thus finding a keto friendly bar can be difficult.

We are going to check out Quest Bars and see if and how they fit into your keto diet regimen.

Protein, Cereal or Hero Bar?

Before we dive deep into the nuts and bolts of how Quest bars fit into the ketogenic diet, let's take a second and clarify which bars are there and what's the difference between them.

So, in a nutshell, Quest offers three types of snack bars:  

  • Protein Bars, as the name states, are high in protein,
  • Cereal Bars are made from grains, and
  • Hero Bar is somewhere between Protein Bar and Beyond Cereal Bar.

From a classical diet perspective, macronutrients for all three bars are good.

All of them are low on carbs when comparing to Snickers or Twix.

It's a perfect snack when you are on the go as it tastes good and you can get it from almost everywhere.

What are Quest Protein
Bars made of?

Quest Protein Bars are one of the most popular fast energy snacks out there. Their main goal is to be fast protein source when you are on the run. These bars are low in carbs and fats.

They taste so sweet due to the sweeteners added in them. So, this is a two-edged sword.

  • On the one hand it is a low-carb snack that can help you out when you are in time trouble or fighting with cravings.

  • At the other end, they contain sugars and sweeteners which may not support your health goals. The main question is if you agree to eat sweeteners or not.  

You can read more about keto-friendly sweeteners form our ultimate sweetener guide here.

Quest Protein Bar ingredients:

  • Protein blend (Whey and milk protein isolate)
  • Erythritol (natural sweetener - sugar alcohol)
  • Soluble corn fiber (prebiotic fiber)
  • Unsweetened chocolate
  • Cocoa butter
  • Almonds
  • Sucralose
  • Stevia
  • Sea salt

It's ingredients are in general pretty okay. It contains quality Whey protein, healthy almonds and natural sweeteners like Stevia and Erythritol. The only negative side is the added sucralose, but fortunately the amount is insignificant. 

Oh, and the biggest perk that this protein bar brings is not the protein nor the taste. What I'm talking about? I'm talking about fiber.

During keto you will be lacking it anyway, especially if you are newbie and just starting out. This is the most delicious way to ramp up your fiber intake. 

Why should you care about fiber? Because lack of it causes constipation.

Should You eat Quest
bars during keto?

Let's face it, they are a treat, and should not be included as main part of your regular keto diet. They are perfect if you truly are on the run, traveling or almost falling off the keto wagon and considering cheat days.

If you don't eat too much of them (staying inside your daily macros), you will not be kicked out of ketosis.

So technically they are keto friendly.

If you are just starting out then keep your net carb intake below 20 grams per day, if you are keto-adapted then below 50 grams per day.

Quest bars are favorite among bodybuilders, Pilates instructors and fitness gurus. If you are on a keto diet and your macros can fit them, then you can enjoy them too.

Hey, we understand that all of us may need snacks during some time of the diet.

But don't start your day with 2 Quest Bars in the morning and 2 in the evening. I suggest using eating them when you are on the run, travelling, cannot eat properly or are fighting with cravings. 

Other Quest Nutrition
Keto Treats

Although Quest Nutrition is a food and nutrition company, it is surprisingly keto-friendly. In addition to keto friendly protein bars, it has actually 3 additional delicious products to offer.

And these fit well into your keto diet - low in carbs, don’t kick you out of ketosis and tastes like heaven. 



#1. Quest MCT Oil Powder

MCT oil is a true keto staple. It provides loads of high-quality fats, helps you to get into ketosis and make your morning coffee bulletproof.

Although there are many MCT oils out there, Quest MCT oil powder is definitely worth trying out. You can read our full Quest MCT oil review here.

It comes in a powdered form, so it doesn't make your drinks oily, and it’s so convenient to take with you when you are on the go.

It’s also reasonably priced compared to competitors.

#2. Quest Protein Cookie

This treat is perfect if you have consistent cookie cravings. Hey, we get it, sometimes you just need to have a cookie.

Fortunately, this is a safe choice. It’s high in fiber and texture is soft and chewy.

One cookie has 4g of net carbs and doesn’t contain gluten nor added sugar.

Fair warning: not all flavors have the same net carb amount. Gingerbread and chocolate chip have 4 grams of net carbs. Others can be slightly more (4-10g).

These protein chips are also a perfect popcorn substitute an ideal movie snack. It's packed with protein and is potato free.

The thickness and texture are similar to a rice-cake type chip with more flavor and very very little mushiness. It resembles real crunchy snacks without the guilt of cheating.

Final thoughts

Quest Bars are truly one of the most popular and affordable snacks out there. Most of them have already decent macros but when it comes to the keto diet, then only the Quest Protein Bar and Hero Bar make the cut.

They are high in protein and low fat and carbs. Both contain 4g of net carbs, which is pretty keto friendly.

Quest protein bars suit well into a keto gift basket.

The main reasons why everyone like them is their sweet delicious taste, which comes from added natural sweeteners like Stevia and Erythritol.

Quest snack bars are keto friendly and they are the perfect solution when you are on the run, are falling off the keto wagon or traveling.

They are the perfect supplement for your diet, but please don’t start your day out with 2 Quest Bars and finish it with 3 more, that's not how it works.

    Just had a quest mint chocolate chip bar for dessert . They are delicious and a dessert for me every night on my keto diet. Still in Ketosis!

    1. Hi Donna!

      Yep, they are delicious, but sometimes can be even too delicious! As long as you stay in ketosis and fat is burning, everything will be superb.

      How much have you lost already?

    you don’t need these – even the owner warned about being kicked out of ketosis on them

    1. Hi Larry!

      I totally agree! You don’t need Quest bars and you shouldn’t add them to your menu just because you can.

      But, if you are falling off the keto wagon, then I suggest eating a couple of quest bars.

      WHY? to kill the cravings. It’s still better than doing a 3-day carb fest full of pizza, burgers, and alcohol. After which you will feel bloated and unmotivated.

      Good luck!

  3. Hi, can you clarify it days 4 net carbs, but 21 carbohydrates listed on the bar it self. That doesnt seem to fit within the diet from my understanding. But I needed a snack.
    Thanks

    1. Hi Danielle!

      When looking for carbs, you need to calculate net carbs. In your case, you need to subtract the amount of fiber (and sugar alcohol if any) from 21g of carbs and you will get the “net carb” count that matters.

      In the table, I have also written about net carbs.

      Good luck!
      Alex

    I’m taking them on my backpacking trip this summer. I need ready to eat food that won’t ruin my keto lifestyle.
