Pallets of bread, mountain-sized boxes of granola bars, a bakery that smells like it’s trying to trap you—walking into Costco on a low-carb diet can feel like a trick. But there’s good news: tucked between all of the temptations, Costco has quietly turned into one of the best places to stock up on low-carb snacks and keto-friendly foods.
Below, we’re rounding up the best low-carb snacks at Costco, plus tips for picking low-carb options without feeling overwhelmed.
Why Costco is one of the best places to buy low-carb snacks
- Better prices per serving. Buying protein-forward snacks like nuts, cheese crisps, protein bars, and jerky in bulk is almost always cheaper per ounce than grabbing single packs at a regular grocery store.
- A dedicated low-carb or keto section. Costco has built out its low-carb selection, stocking more options and popular brands.
- High-protein, whole foods. Rotisserie chicken, eggs, Greek yogurt, cheese, nuts, and seafood are all naturally low-carb and readily available throughout the grocery section.
- A freezer section ideal for meal prep. Riced cauliflower, pre-cooked proteins, and low-carb frozen entrees make it easier to build real meals while sticking with your low-carb nutrition goals.
How to choose the best low-carb snacks at Costco
Before you start filling your cart, here are a few things to look for to ensure you stay on the low-carb track:
Check net carbs
Total carbs on the label include fiber, which your body processes differently than other carbs. Those who follow a low-carb or keto diet look at net carbs instead of total carbs to determine whether a food is "low-carb." Net carbs are the total carbs minus fiber and sugar alcohols, if the product contains them. So, a snack with 10 grams of total carbs and 8 grams of fiber has a completely different effect than one with 10 grams of carbs and zero fiber.
Double-check net carbs with the MyNetDiary app. Use the food barcode scanner on low-carb products, and its nutrition profile will pop right up!
Look for high protein
Protein makes a snack satisfying, tiding you over between meals and helping you hit your diet goals. Aim for 7-10 grams of protein per serving. Cheese, protein bars, jerky, dairy products like Greek yogurt, legumes, and nuts are all excellent high-protein picks.
Avoid added sugars
Just because something is labeled “healthy” or “protein-packed” doesn't mean it's sugar-free. Watch out for sneaky added sugar in sauces, coatings, or dried fruit. Flip the package and check the “Added Sugars” line specifically.
Watch serving sizes
Food products at Costco are often in much larger packaging than the “one serving” listed on the nutrition label, so it’s easy to eat 2 or 3 servings without realizing it. Pre-portioning snacks into small containers or bags at home to avoid accidental overindulging, whether you’re new to low-carb eating or you’ve been burned by the “family-size” bag before.
10 Best low-carb snacks and foods at Costco
Here's our dietitian-recommended list of the best low-carb snacks at Costco.
Whisps Parmesan Crisps
Made from just one ingredient—Parmesan cheese—Whisps are about as non-nonsense as low-carb snacks get. A serving—roughly 14 crisps—delivers 160 calories, zero carbohydrates, and 13 grams of protein. They are a fantastic alternative to cheese and crackers. With so many crisps per serving, Whisps satisfy any munchy craving!
Seaweed snacks
Roasted seaweed is about as low-calorie and low-carb as packaged snacks come, with one sheet clocking only 20 calories and less than one gram of carbs. It’s a great pick when you’re craving something salty and crunchy with few calories, plus you get iodine and other trace minerals not available in other snacks. A single package is tiny, so treat it as a light nibble rather than an afternoon meal.
Olive snack packs
Individually portioned olive pouches are one of the most underrated finds in the snack aisle. One pouch packs about 50 calories, plus one gram of carbs and heart-healthy unsaturated fats. No refrigeration needed until opened, no mess, and they’re a nice addition to a low-carb lunch box or snack plate.
Roasted edamame snack packs
Roasted edamame snack packs are a convenient way to ramp up your fiber intake while remaining low-carb. Each pack contains 110 calories, just 2 grams of net carbs, and 12 grams of protein. Great for low-carb plant-based eaters, or anyone who wants to keep fat lower while still sticking to a low-carb diet.
Mini guacamole cups
Individual guacamole cups are the answer to the browning big tub you’re nowhere close to finishing. One little cup (2.5 ounces) runs 80 calories with 2 grams of net carbs, plus the heart-healthy fat that avocado is known for. Skip the tortilla chips, and dip the guac with fresh veggies to keep the whole snack low-carb.
Unsalted mixed nuts
A quarter-cup (1 ounce) serving of unsalted mixed nuts has about 170 calories, 5 grams of net carbs, and 5 grams of protein, as well as a hefty dose of unsaturated fat. Nuts are calorie-dense, so portioning is especially important here. Purchase individually packaged bags, or create your own small containers for an easy grab-and-go, low-carb snack.
Chomps Beef Sticks
Chomps Original Grass-Fed Beef Sticks have earned their cult following. Each stick has about 100 calories, 0 grams of carbs, and 10 grams of protein, and is made from grass-fed beef with no added sugar and no weird ingredients. Individually wrapped, shelf-stable, and about as close to a true zero-carb snack as you’ll find.
Hard-boiled eggs
Already cooked and peeled and sold in convenient 2-count packs, so there’s no prep work for you. One egg runs you about 68 calories, 0 grams of carbs, and 6 grams of protein, plus a solid dose of choline. They’re a great snack to toss in your lunchbag or purse for a good punch of protein with no carbs, making them an easy way to reach your protein goals.
Catalina Crunch Cereal
Catalina Crunch is a plant-based, high-fiber cereal built with low-carb eating in mind. A half-cup serving has about 110 calories, 5 grams of net carbs, and 11 grams of protein. It won't fool anyone into thinking it’s their childhood cereal. Still, it does offer a higher protein and fiber boost than any traditional cereal ever will.
Best Costco low-carb frozen meals worth buying
Costco’s freezer aisle has become a great resource of low-carb meals and other keto foods too:
- Real Good Foods Cauliflower Crust Pizza: Cheese and cauliflower stand in nicely for traditional dough, resulting in 12 grams of net carbs and a whopping 40 grams of protein per half pizza, depending on the toppings.
- Real Good Foods Chicken Enchiladas: A protein-rich frozen entree with roughly 32 grams of protein and 10 grams of net carbs per serving.
- Frozen wild-caught salmon and chicken breast: Less low-carb and more zero-carb, these bulk frozen proteins are the foundation for endless low-carb dinners.
Frozen meals vary a lot by brand and sauce, so it’s worth reading the label rather than assuming a food is low-carb, even if it's labeled as keto or contains cauliflower.
Meal ideas using Costco low-carb foods
A few easy ways to mix and match everything above into full meals or snack plates:
- Protein snack plate: Chomps beef stick, a handful of mixed nuts, and a mini guacamole cup with cucumber slices.
- Low-carb breakfast bowl: Catalina Crunch cereal with unsweetened almond milk, topped with a spoonful of nut butter.
- Quick lunch: Hard-boiled eggs with cheese slices, paired with a Greek yogurt cup, and a few olives.
- Easy dinner: Riced cauliflower sautéed with rotisserie chicken, topped with crumbled Whisps for crunch.
- On-the-go combo: Seaweed snacks and Whisps Parmesan Cheese.
Common mistakes when buying low-carb snacks
Watch out for these common shopping mistakes when looking for low-carb snacks:
- Trusting the front of the package. “Keto” and “low-carb” claims aren’t regulated the same way everywhere. Always flip it over and check the actual nutrition panel.
- Ignoring serving size on bulk packaging. A bag that looks like “one snack” might actually contain 3 or 4 servings.
- Overlooking added sugar in sauces and coatings. Flavored nuts, jerky, and dips are frequent offenders.
- Treating nuts and cheese like unlimited “free foods.” They’re low-carb, but calorie-dense, so portioning is crucial if weight management is in your game plan.
- Not reading labels close enough. Misreading the fiber content means an inaccurate net-carb count—miss this line item, and it can cost you carbs and calories.
Can Costco keto snacks support weight loss?
Low-carb and keto-friendly snacks can absolutely fit into a weight-loss plan, but it’s your overall calorie balance that matters more. A lot of the items on this list are calorie-dense, so thinking you can eat as much as you want just because they’re “low-carb” can stall progress just as easily as overeating any other food.
Research shows that following a low-carb or keto diet may lead to greater initial weight loss than overall calorie reduction. However, weight loss appears to be equal across other dietary approaches in the long term. In fact, there’s limited evidence for the sustainability of a keto diet beyond 12 months. What matters most is the calorie deficit rather than the macronutrient makeup.
