Whisps Parmesan Cheese Crisps have zero grams of sugar but also provide 13 grams of protein per serving. Perfect for a mid-afternoon pick-me-up or to give a sandwich or salad that perfect crunch you’re craving.

“In my opinion, they are a perfect snack for people following a ketogenic diet. Alternatively, you can use them as a topping for casseroles and salads,” Megan Darlington, RD.

2. That’s it. Mini Fruit Bars

That’s it Mini Fruit Bars are a clean, simple, no-nonsense food that is low in added sugar. Coming in several delicious flavors, there’s a That’s It bar to conquer any sweet craving.

“That’s It Mini Fruit Bars are an excellent choice for people seeking a quick, healthy snack. The bars contain only two ingredients with no added sugars. Yes, the bars do technically contain between 9 to 13 grams of sugar; however, these are natural sugars that will provide you quick, consistent energy, and keep your metabolism stable,” Darlington says.

These on-the-go snacks have 4 grams of protein in each stick and zero grams of sugar. Plus these grass-fed beef sticks are made with all real ingredients.

Though Costco offers several different beef jerky sticks, these are one of Reisdorf’s favorites due to their high protein and “no carbs or sugar” nutrition.

6. Simply Protein Bars

Simply Protein Bars offer that snacky feeling without all the extra stuff that might make you crash later. These bars also offer a natural source of sweetener, so you’re still satisfying that sweet tooth craving but keeping the sugar low.

“I like that this bar is both a source of protein and low in sugar. I also like that they’re plant-based, are a good source of fiber, and don’t contain artificial sweeteners like many low or no sugar products do (instead they have monk fruit as an additional natural sugar-free sweetener),” Avery Zenker, RD at EverFlex Fitness says.
