If you have a goal to slim down or improve your fitness, eating healthy snacks between meals is just as important as what you choose for your main meals. That's because, for most of us, snacks contribute to about a third of our daily calories. One of the best ways to choose healthy, nutrient-dense snacks that help keep you satisfied is to look for a wholesome protein bar.

Research shows that eating a diet that optimizes protein at about 1.2 to 1.6 grams per kilogram body weight (.5 to .7 grams per pound body weight) or about 20-30 grams of healthy protein sources per meal, can lead to better weight management and lower body fat while reducing risk for some chronic health conditions. Having the right high-protein bars on hand can help you when you need a between-meal snack that will keep you on track.

How we selected the best healthy protein bars:

To help you find a high-protein bar that can help you lose and maintain a healthy weight, here's what to look for:

  • High protein counts: Look for a bar that provides at least 10 grams of protein. Since meals should provide 20-30 grams of protein, you're looking for a bar with about half of the protein that a meal should provide.
  • Moderate calories: Make sure the protein bar has no more than 300 calories. Snacks should be kept to up to 250-300 calories to help ensure that you don't exceed your daily caloric budget.
  • Low in added sugar: Be sure to choose a protein bar that limits added sugars to no more than 10 grams or 2.5 teaspoons. Added sugar is digested and absorbed quickly, and provides no staying power, so you'll likely be hungry soon after eating. One exception is if you are eating a snack post-exercise, as it's okay to have more added sugar to help replenish depleted glycogen stores after exercise.
  • High in fiber: When it comes to fiber, choose bars with at least 3 grams of fiber. Fiber will help keep you satisfied, improve your GI health, and help reduce the risk of chronic diseases.
  • Made with wholesome ingredients: Bars that have more natural ingredients should be prioritized, like nuts, seeds, and whole grains.
