28 Low-Carb, High-Protein Fitness Bars for Muscle Growth

Whether you’re looking to lose belly fat or gain lean muscle mass, a candy bar wouldn’t be your top contender come lunchtime. So why would you purchase a protein bar with a nutritional profile similar to a Milky Way?

But, hey, you already knew that—that’s probably why you’re looking for a list of low-carb protein bars.

There are countless reasons you may want a low-carb protein bar: you’re seeking a light snack to satisfy cravings on the go, you’re following a low-carb or keto diet, you prefer a protein-packed meal replacement, or you want to lose weight. That’s right: Increasing your protein intake while decreasing your carb intake has been shown to improve weight loss maintenance over time, according to a study published in The New England Journal of Medicine.

To help you on your path to a healthy life, we’ve compiled a list of low-carb, high-protein bars so you get the best of both worlds. And the best part: all of these bars win our taste buds’ seal of approval. If you’re looking for more ways to increase your protein intake, don’t miss out on these 25 Best High-Protein Snacks.
