These 9 Low-Carb Protein Bars Will Make Going Keto Easier Than Ever

No carbs? No problem.

Low-carb and ketogenic—keto— diets are extremely popular for those who want to lose weight. They're effective, too, in the short term, thanks to cutting out (or cutting back) an entire food group.

While low-carb and keto are technically different diets—the keto was originally designed to help those with epilepsy—both reduce or eliminate carbohydrates. A low-carb diet limits the daily amount of carbs a person consumes, focusing on high-protein intake.

But unlike keto, more on that below, there's no clear definition of what constitutes a low-carb diet. Technically if carbohydrates constitute 45 percent or less of your total calories, your diet could be considered low-carb, says Pamela Nisevich Bede, R.D., author of Sweat. Eat. Repeat. Bede says that often, people who start on a low-carb diet typically consume similar numbers to keto, with around 10 to 20 percent of their total calories coming from carbohydrates.

Which brings us to...

The restrictive keto diet. The goal is for the body to go into ketosis and burn fat instead of carbs for energy. It focuses on high fat, with just 20 percent of calories coming from protein and 10 percent coming from carbs. Goodbye, breakfast bagels.

Dezi Abeytas, R.D.N., a Men's Health nutrition advisor, says certain protein bars are a great addition to a keto or low-carb diet. "Bars offer a great deal of sustainability," he says. "When we're super busy and can't make a meal or we're on the go and only have snack in our bag, they're a really great supplement to a balanced diet. And some are whole-foods based, meaning they're close to their natural source of food."

For low-carb and keto, you'll want at least 10 grams of protein. Abeytas says some people may even want to look for 15 to 20 grams of protein, depending on what their goals are, whether it's weight loss, building muscle, or training for a marathon. But those looking for low carbs in their bars should read the food labels closely. "If I'm looking for a keto bar, I'm looking for a variant in which most of the calories are going to come from fat," Bede tells Men's Health.

Protein bars are perfect for a post-workout snack, road trips, or to keep your stomach from grumbling while you're working. But different bars serve different purposes, so you need to know what to look for. Abeytas and Bede agree that the right bar for you might not be the right bar for your CrossFit buddy.

"Maybe you're looking for dessert, but you want something a little bit healthier," Bede says. "Or maybe you just finished a workout and you need 15 to 30 grams of protein. Or maybe it's a meal replacement."

If you're a keto dieter, Bede and Abeytas say to choose bars with fewer than five net carbs: "There are carbohydrates and then there are net carbohydrates," Bede says. "There's no regulation or definition around it, but most of us agree a net carb is when you consider total carbs, and you take out fiber, you take out sugar alcohols, and you subtract out allulose as well."

Another factor to consider: taste.

"Does it taste good? Because sometimes you run into a bar that's just nasty," Abeytas says. Although the label may say it's cookie dough-flavored, it might just taste like chalk. Be sure to test out different brands to see which ones you like the best.

Below are nine protein bar picks for low-carb or keto diets.
