Low Carb Protein Bars Buyer's Guide
What are the best low carb protein bars?
Low-carb protein bars are incredibly useful for managing your diet and avoiding unnecessary weight gain, as well as improving your general health when you're out and about. As you might have noticed from this list, the best options for low-carb diets simply the ones that contain the least carbs and/or sugars, since these are the two things that are most likely to affect your performance and physical health when it comes to snack bars.
It usually comes down to personal preference. If you prefer dark chocolate to peanut butter, then you'll choose the protein bar that you enjoy the taste of more. The best low-carb option is whichever one you're most comfortable using on a regular basis, after all.
What is the healthiest protein bar?
Again, the “best” option depends on what you need and the diet you're following. Remember that more protein isn't always better – the more protein you're taking in, the larger the bar might be, and that increases the amount of extra ingredients you'll be eating. The healthiest option for you should be one that’s an appropriate size for your level of activity and muscle development.
The best protein bar brands will focus on more than just cab count and collagen protein – they'll also handle fiber, nutrition and other important dietary elements well too. If your protein bar lacks a decent amount of fiber, it'll probably be worse for you overall than a high-fiber bar.
What are good high protein low carb snacks?
While there are various foods that contain plenty of protein and very few carbs (including cottage cheese, jerky, trail mix and tuna), very few are as portable and space-efficient as good snack bars. That doesn't mean you should ignore them entirely, but don't be afraid to use a snack bar if you're hungry and don't have time for a full meal.
A decent protein bar won't just cut down on your carb intake, but will also give other kinds of nutrition. For example, fiber is a major part of any diet, and dropping it entirely to lower your carb intake will end badly for your body.
What bars are keto friendly?
Bars that offer ketogenic-friendly ingredients will usually display that on their packaging. Keto diets essentially involve cutting down on carbs and eating more fat instead, so any bar that contains more fat than carbs can be suitable – you'll also one that with a suitable amount of sugar, since keto can affect your blood sugar levels too.
Expert tip:
Sugar won't always be called sugar on the packaging: look for things like maple syrup, honey, agave nectar, etc. to get an idea of how much sugar a bar may actually contain.
Did you know?
Sugar alcohols are some of the worst types of sugar to deal with in a protein bar – avoid them as best as possible.
