In order to keep carbs to a minimum, lots of keto-friendly creations call upon sugar alcohols to help boost the flavor. Unfortunately, however, these sweeteners can cause bloating and gut troubles, especially if you have a sensitive tum, says Beth Warren, RDN, the author of Secrets of a Kosher Girl and founder of Beth Warren Nutrition. These are your best bet for steering clear of any unnecessary bathroom situations.

How to Choose A Keto-Friendly Protein Bar

The keto diet is all about counting your macronutrients—a.k.a. how many grams of carbs, fat, and protein you eat on the reg. In order for a protein bar to be keto-friendly, it has to be low in carbohydrates and high in fats—specifically, any product or recipe macro make-up should be 60 to 75 percent fat, 15 to 20 percent protein, and 10 percent or less of carbs, says O'Connor. "That being said, as long as your low-carb bar has quality, whole ingredients and plenty of healthy fats, the numbers don't have to be exact."

While the numbers don't have to be perfect, the closer a bar is to that ratio, the better, as this will help you meet your daily macro needs. So, sticking to O'Connor's recommended ratio will help you choose protein bars that best support all this macro counting or, simply, the diet.

Another priority when picking a keto protein bar? Whole-food ingredients, O'Connor says. This means looking for bars that prioritize healthy fats and whole proteins over powders and supplemented vitamins. Steer clear of preservatives, artificial sweeteners, and processed fats.

Look for ingredients like medium-chain triglycerides, or MCT, oils (a type of healthy fat), extra-virgin olive oil, cold-pressed coconut oil, avocado, nuts, hemp hearts, and seeds. Pro tip: If you're sensitive to carbs or doing strict keto, skip the nuts and stick to straight oil.

Good protein choices include wild-caught fish, grass-fed meat, poultry, or eggs, she says. If you're looking for a more cost-friendly alternative, whey or collagen powders also pack a clean protein punch.
