Top 10 Protein Bars for Building Muscle, Fat Loss

best protein barsLooking for a way to supplement your protein?

Want to support your goals of muscle building?

Ready for a protein bar that curbs appetite AND tastes great?

Finding the ideal protein bar to support your fitness goals isn’t easy. There are literally hundreds of options; many of which aren’t right for your needs.

Let’s take a look at the importance of protein bars in a healthy diet and exercise program and what to look for when shopping for one. More importantly, we’ll give you access to the top 10 protein bars for muscle building and fat burning.

Wholefood vs. Supplements

First and foremost, it’s important to understand that when it comes to achieving your goals of muscle building or losing weight, wholefood nutrition must be your primary focus. Eating a well-balanced diet that is set to your specific goals makes up 70% of the results that you see.

Do supplements play a hand in the results you see as well? Of course; however, supplements are only there to supplement your diet. Supplements should never be the focus of your day-to-day meal planner.

Your body requires wholefood nutrition as the nutrients found in real food are easy to digest and easier to assimilate. What’s more, the nutrients you get from wholefood sources such as lean meats, vegetables, and super foods are natural. You don’t have to worry about artificial sweeteners or fillers like you do with some low-quality supplements.

With that said, supplements, especially protein bars, can play an important role in achieving your specific goals.

Protein Bars for Fitness Goals

Protein is important for all types of fitness goals with an emphasis on building muscle, losing fat, and improving fitness recovery.

When it comes to muscle building, protein is a necessity. This is why protein supplements such as powders and bars are so popular (you can view our best whey protein powders here for a liquid alternative). Once ingested, protein is broken down into amino acids and these compounds are the building blocks of muscle tissue. Supplementing with protein may help to trigger higher levels of protein synthesis, support lean tissue growth, and protect muscle from catabolic breakdown. (1-5)

For weight loss and burning fat, protein is just as important. Protein provides a feeling of satiety after a meal, which means that you’ll feel fuller for a longer period of time. Simple carbohydrates tend to spike blood sugar and leave you feeling hungry. This may result in over-eating, which can throw your weight loss off-track. What’s more, certain amino acids such as isoleucine have been found in studies to promote fat loss. (5)

Lastly, protein is important for sports recovery. Sufficient protein intake in conjunction with an exercise program has been shown in several studies to enhance recovery post-workout. Studies suggest that protein ingested before and after a workout will also improve intra-workout performance. (6-7)

Macronutrients & Protein Bars

Despite the labelling you see on supplements, not all protein bars are created equal. More importantly, one specific brand of protein bar is not going to be ideal for everyone.

Macronutrients are the three types of calories: proteins, carbohydrates, and fats. Based on fitness goals and body type, macronutrient requirements will vary from person to person. Just like people, protein bars have a vastly different macronutrient content from bar to bar. The inconsistency with macronutrients across protein bars can create problems, especially if your personal macronutrient needs aren’t being met.

For example, if you are trying to lose weight and you eat a “protein” bar that has 8 grams of protein and 28 grams of simple carbohydrates, you’re not eating a protein bar; you’re eating a candy bar.

To avoid making these mistakes, we recommend that you establish your personalized caloric intake and macronutrient needs with a calorie calculator.

How to Find the Best Protein Bar Macros

Here are ideal macronutrient ratios based on your specific goal that you should look for in any protein bar you pick up.

Calories for One Gram of Each Macronutrient

  • Protein: 1 gram = 4 calories
  • Carbohydrates: 1 gram = 4 calories
  • Fat: 1 gram = 9 calories

Macronutrients for Muscle Mass

  • 45% of calories from protein
  • 45% of calories from carbohydrates
  • 10% of calories from fat

Example: Use this formula for your own protein bar to make sure it is meeting your needs.

  • For a protein bar that is 200 calories:
  • 45% of the calories should come from protein: 90 calories (200 x .45 = 90)
  • 90 / 4 (calories per gram) = 22.5
  • Your protein bar should have at least 22 grams of protein

Macronutrients for Fat Loss

  • 45% of calories from proteins
  • 40% of calories from carbohydrates
  • 15% of calories from fats

Now, if you are going to supplement with a protein bar (and we suggest that you do) be sure to match the protein to your personal fitness goals. Here is our list of the best protein bars to support muscle building and fat loss.
