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.

But when it comes to keto, then Beyond Cereal Bar don’t make the cut thanks to its high sugar composition. Cereal bar contains 8g of sugar.

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.

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.
