Pumpkin seeds are the protein source in these bars, providing about 12 grams per serving. Maple syrup is used instead of honey, keeping them 100 percent vegan and there are only 4 to 5 grams of added sugar per bar. They're also loaded with iron — a bar meets 20 percent of your daily needs — which is especially important if you're following a plant-based diet.

Quest bars are high in protein and fiber — two satiating nutrients — while being low in sugar.

If you're comfortable with artificial sweeteners and sugar alcohols (which can cause GI distress when consumed in excess or if you have a sensitive stomach), then they're a solid choice for a low-sugar, high-protein option. Quest bars come in a variety of different dessert-inspired flavors, but our favorites are Chocolate Chip Cookie Dough and S'mores.

These bars are unique in that they are keto-approved (if that's your thing), plant-based, free of artificial sweeteners or sugar alcohols and palm oil-free, too. Their nutrition profile is perfect for a snack with around 180 calories, 9 grams of protein and 12 grams of fiber.

The Hungry Buddha bars are sweetened with monk fruit, which is a zero-calorie sweetener extracted from a melon grown in Southeast Asia.

5. Sans Meal Bar

They’ll keep you satisfied, with about 17 grams of protein and 8 grams of fiber.

Per serving (Coconut Almond Butter): 380 calories, 22 grams fat (4.5 grams saturated fat), 240 milligrams sodium, 34 grams carbohydrates (8 grams fiber, 22 grams sugar, 0 grams added sugar), 17 grams protein

The Sans bar is higher in calories — around 380, depending on the flavor — so for many, this would be a good fit as part of a meal replacement when you need something quick or you're on the go. They're called "Sans" because they are sans, aka "without," questionable ingredients. Instead, you'll find ingredients like almonds, egg whites, oats, dates, coconut, flaxseed and spinach powder. They are higher in sugar, but it comes from low-glycemic dates.

6. Kize Bars

Kize's flavor variety makes sure there’s truly something for everyone.

Per serving (Peanut Butter Cookie): 200 calories, 15 grams fat (7 grams saturated fat), 210 milligrams sodium, 11 grams carbohydrates (5 grams fiber, 4 grams sugar, 0 grams added sugar), 8 grams protein

"These bars are perfect for an afternoon snack and are made with whole-food ingredients like peanut butter, honey, oats and dates, with a protein boost from egg whites (some contain grass-fed whey)," says sports dietitian Kelly Jones, RD, CSSD.

And you can feel good about your purchase: "I love Kize as a company and am drawn to their bars since they provide food and monetary support through the With All My Heart Foundation," Jones says.

2 Protein Bars to Avoid

1. Met-Rx Bars

Per serving (Birthday Cake): 420 calories, 13 grams fat (8 grams saturated fat), 260 milligrams sodium, 47 grams carbohydrates (0 grams fiber, 25 grams sugar, 24 grams added sugars), 30 grams protein

Sure, this bar has a high 30 grams of protein but it's also stuffed with too much added sugar and saturated fat, which isn't good for your heart health.

The American Heart Association (AHA) recommends getting no more than 25 to 36 grams of added sugar per day, and this bar contains almost a full day's worth. The AHA also recommends getting no more than 5 to 6 percent of your daily calories from saturated fat (that's about 13 grams on a 2,000-calorie eating plan), and the 8 grams in this bar comes quite close.

Not to mention, the Met-Rx bar contains 420 calories, acting more as a meal replacement than a snack. A nutritious snack should contain some fiber to keep you full, and this bar contains none.

2. Balance Bars

Per serving (Yogurt Honey Peanut): 200 calories, 6 grams fat (3 grams saturated fat), 170 milligrams sodium, 22 grams carbohydrates (1 gram fiber, 18 grams sugar, 17 grams added sugar), 15 grams protein

Balance Bars are low in fiber and contain a lengthy ingredient list devoid of whole foods. For example, the first six ingredients are protein blend, fructose, glucose syrup, partially defatted peanut flour, peanut butter and sugar. There are three types of sugar in the first few ingredients alone, which make up the high 18 grams of total sugar.

These bars may appear uber-healthy because they're fortified with almost every single vitamin and mineral — but if that's what you're after, you're better off taking a multivitamin.

What to Look for When Choosing a Protein Bar

When shopping for protein bars, check the following:

  • The ingredient list:‌ Ideally, the ingredient list will include mostly whole foods like nuts, fruit and egg whites. While avoiding any ingredient you can't pronounce isn't sound advice, you do want to have a sense of what it is that you're eating.
  • Caloric amount:‌ There's no hard and fast rule here; it really depends on your needs. Is this a small snack, a big snack or are you eating a bar as part of your meal? There are bars on the market that have around 100 calories and there are others that are closer to 400. Depending on how hungry you are or what you're looking for should drive this decision.
  • Grams of protein:‌ Ideally, a bar will have about 10 grams of protein or higher. That said, if there's a bar you love that fits all of your other requirements, then, by all means, enjoy. Protein is satiating and it helps to slow digestion (along with fat), so it's helpful to include it in a snack to help tide you over, per a June 2016 paper in ‌Annual Reviews‌.
  • Some fiber:‌ Fiber is another nutrient to take into consideration. A bar with 3 grams of fiber or more is perfect for a snack. Like protein, fiber helps us to feel fuller longer.

What to Avoid

There are also a few things you'll want to avoid when it comes to shopping for protein bars:

  • Additives and other ingredients:‌ There are some ingredients commonly used in protein bars that you may want to avoid like artificial sweeteners, sugar alcohols, certain gums and other additives.
  • Added sugars:‌ Because we want to try and avoid artificial sweeteners and alcohols, other sugars like honey or brown rice syrup may be added to help sweeten the bar. Keep in mind that the AHA recommends keeping added sugar intake to 36 grams or less.
