#1 Onnit Protein Bites

Key features

  • Net Carbs: 8 grams
  • Flavors: Broad variety including fan favorites
  • Main Protein Source: Grass-fed whey and milk proteins
  • Protein Per Serving: Up to 9 grams

What we love:

  • Varied Nutrition
  • Convenience
  • Subscription Savings
  • Quality Ingredients
  • Taste and Texture

What to consider:

  • Allergen Advisory: Contains common allergens including soy, tree nuts, milk, and sesame.
  • Mixed Reviews: Customer opinions on the new formula are split, indicating varied taste preferences.
  • Potential Mess: The chocolate coating may melt easily, which could get untidy.

Why we choose Onnit Protein Bites:

Onnit Protein Bites was underpinned by our insistence on excellence — both in dietary impact and ethical production. We stand behind Onnit’s Protein Bites as a product of superior quality and effectiveness, cementing our confidence in recommending them to our health-centric community.


Onnit Protein Bites pack 7 to 9 grams of quality protein from grass-fed cows, alongside an impressive variety of plant-derived nutrients. However, opinions on the new formula’s taste profile are polarized.

With a protein lineup from whey and milk proteins of grass-fed cows, alongside a comprehensive plant blend, these bites won’t win over fans of minimalist ingredient lists. Regardless, they manage to provide 9 grams of protein largely from whey protein isolate and milk protein isolate.

The cows supplying the milk for Onnit Protein Bites graze on grass for an average of 300 days annually, without growth hormones, producing non-GMO milk. Offered at $1.66 per serving (or $1.41 with a subscription), these bites are an economical option.

Despite containing several allergens, they remain a competitive choice in terms of price and nutrition per serving. The bites are sweetened with agave syrup, capping sugar content at 7 grams, while keeping carbs and calories low.

During our extensive review, the Cookies and Cream flavor was a standout, carrying approval from numerous testers. One of the reviewers says, “Although it’s not the highest in protein, it’s akin to a healthier indulgence for those with a sweet tooth.”

How Do Low-Carb Protein Bars Work?

The magic of low-carb protein bars lies in their unique nutritional blueprint. They’re all about balance – a delicate dance between providing you with the vital protein you need while keeping those pesky carbs at bay.

Protein is the star here. It’s the building block of our bodies, crucial for repairing and creating new cells, not to mention supporting muscle growth[1]. When you take a bite of a low-carb protein bar, your body gets a burst of high-quality protein that’s easy to digest and absorb.

Now, what about the low-carb part? Carbohydrates are our body’s go-to energy source. But when we limit them, the body has to find fuel elsewhere. This is where fats come in. In a low-carb state, our bodies turn to fat for energy, a process known as ketosis[2].

So, these low-carb protein bars essentially provide you with double benefits. You’re getting the protein you need for muscle maintenance and growth, while the low carb content supports your body’s shift towards burning fat for energy. It’s a synergy that works wonders for those balancing fitness goals with dietary restrictions.

How We Tested and Picked the Best Low-Carb Protein Bars

To identify the best low-carb protein bars, we went in deep. We spent months sampling various products, scrutinizing their nutritional profiles, and savoring their taste. Our approach was comprehensive: we considered net carb content, protein quality, taste, and customer reviews.

We also kept an eye out for any hidden sugars or artificial additives that might compromise the health benefits. After rigorous testing and analysis, we shortlisted those that truly delivered on the promise of being high in protein, low in carbs, and delicious.

This wasn’t just a numbers game – we wanted to ensure these bars would genuinely enhance your dietary journey while offering a satisfying snack or meal substitute.

Benefits of Low-Carb Protein Bars/ Keto Protein Bars

Low-carb protein bars aren’t just a convenient snack; they come with a host of benefits that make them a worthy addition to your dietary routine. Here are some of these advantages:

High-Quality Protein

keto protein bars are packed with quality protein, essential for muscle repair and growth[1]. Whether you’re a fitness enthusiast or just someone aiming to maintain a healthy body, keto protein bars provide a quick and easy way to meet your daily protein needs.

Supports Weight Management

The low-carb aspect contributes to weight management. By limiting carb intake, your body is encouraged to burn fat for energy, which can support weight loss goals. Plus, protein helps keep you satiated, curbing unnecessary snacking[3].


In our fast-paced world, finding time for a balanced meal can be a challenge. Low-carb protein bars offer a convenient solution. They’re portable, quick to consume, and don’t require any prep time – making them a perfect on-the-go option.

Energy Boost

Despite being low in carbs, keto bars can still provide a steady release of energy. This is thanks to the protein and healthy fats they contain, which are excellent sources of sustained energy[4].


Whether you need a pre-workout fuel, post-workout recovery, or just a midday snack, low-carb protein bars fit the bill. They’re a versatile option that can adapt to your dietary needs throughout the day.

Who Should Use Low-Carb Protein Bars/Keto Protein Bars?

  • Fitness Enthusiasts: If you’re regularly hitting the gym, running, or engaging in any strenuous physical activities, keto bars can help fuel your workouts and aid in recovery by providing a quick and convenient source of protein[1].
  • Weight Watchers: If you’re on a weight loss journey, keto protein bars can be a game-changer. The combination of high protein and low carbs can help manage hunger pangs and support fat-burning [5].
  • Busy Bees: For those with a hectic schedule, finding time to prepare a nutritious meal can be tough. Low-carb protein bars are a quick, easy, and portable solution that can fill the gap when you’re on the go.
  • Low-Carb & Keto Dieters: If you’re following a low-carb or ketogenic diet, keto bars can align perfectly with your dietary goals, helping you keep carb intake in check while providing necessary protein.
  • Healthy Snackers: If you’re someone who loves a good snack but wants to keep it healthy, low carb bars offer a satisfying option that won’t derail your nutrition goals.

How To Choose The Best Low-Carb Protein Bars/ Keto bars

Here are some key factors to consider when making your choice:

  • Protein Content: Look for keto bars that offer a substantial amount of protein (around 20g per serving is a good benchmark). This ensures you’re getting a meaningful dose of this vital macronutrient.
  • Net Carbs: Check the net carbs – that’s total carbs minus fiber and sugar alcohols. Fiber and sugar alcohols, although technically carbs, aren’t fully digested by your body, hence, they don’t contribute to your blood sugar levels. The lower the net carbs, the better it aligns with a low-carb diet.
  • Quality of Ingredients: Scan the ingredient list. Opt for bars made with whole food ingredients and avoid those loaded with artificial additives or sweeteners.
  • Sugar Content: While we all love a little sweetness, too much sugar can lead to health issues such as weight gain and heart disease. Even if a bar is low in carbs, it could still be high in sugar. Look for protein bars with low sugar content to keep your nutrition on track.
  • Taste: We’re all human, and we all want our food to taste good! So, while it’s important to consider the nutritional content of your protein bar, don’t forget about the flavor. Choose a bar that you enjoy eating – there’s no point in a healthy snack that you have to force yourself to eat.
  • Dietary Needs: If you have specific dietary needs or restrictions (like gluten-free, vegan, etc.), ensure the bar meets those requirements.
