Here's the situation: It's the middle of the day—right after lunch, but still too early for dinner—and you're so hungry. Most people can just pick up a protein bar and get on with their lives, but for people on the keto diet, things aren't quite so easy (why must everything have carbs?!).

Luckily, there are still keto protein bar options out there—you just have to know what to look for, because staying in ketosis is likely your main goal. "When following a Keto diet plan, it's important to eat the right foods to stay in ketosis. Ketosis is an all or nothing deal—either you're in ketosis or you're not," Melissa Nieves, RD, of Healthy Meals Supreme tells Health.

So what exactly should (and shouldn't) be in a keto protein bar? Nieves suggests starting with the ingredient list—specifically how short or long it is. "As a quick, simple approach, the less ingredients a bar has, the better," she explains.

Your best bet is to choose bars with plant-based fats (coconut oil, avocado oil), that have low amounts of sodium (no more than 140 mg of sodium per portion), and less processed ingredients.

It's also important that they have sufficient protein and fiber, in order to help with satiety. "One of the most common complaints from those following the keto diet is constipation, and adding more fiber to the diet can help counteract this effect," she adds, pointing out that a high fiber food, should boast 3 grams per serving.

And, because keto is all about that delicate fat-protein-carbohydrate ratio, the macros of each bar is important, too: "When it comes to keto-friendly bars, you should look for ones with net carbs less than 7g, protein between 7-8g, fat around 15g, fiber between 8-9g and added sugar at 3g or less," Arthur Agatston, MD, author of The New Keto-Friendly South Beach Diet: Rev Your Metabolism and Improve Your Health With the Latest Science of Weight Loss, tells Health.

Still a little confused? Don't worry, we've got your back. Here, 11 nutritionist-approved keto bars you can eat on the go—and that won't kick you out of ketosis.

You can still maintain a plant-based diet and do keto. If you are trying to keep your consumption of animal products at a minimum, Aristotelous suggests trying a Dang Bar. "It will help you adhere to a ketogenic nutrition plan without any animal products with healthy fats and proteins such as coconut, pea protein, almonds, Chia seeds, and cocoa butter," she explains. This plant-based bar boasts 15 grams of fat, nine grams of protein, and five grams of net carbs.

Gabby Geerts, RD at Green Chef is a big fan of Epic Provision's bars, as they offer grass-fed protein with only a few simple ingredients. "These bars are great for a keto eater," she reveals. "Very low in carbs, with 5 grams or less, these flavors take the confusion out of keto snacking." Their Chicken Sesame BBQ Bar, for example, boasts a whopping 13 grams of protein. She does warn that many of their flavor varieties contain dried fruit, which wouldn't comply with keto diet.
