Finding a snack that actually keeps you full without blowing your calorie budget for the day is the constant challenge. You want something that hits the spot, delivers real protein, and doesn’t taste like cardboard — and the options on store shelves are often loaded with hidden sugars or unsatisfying portions.
I’m Emma — the founder and writer behind Baby Bangs. I’ve spent years analyzing the nutritional breakdown, ingredient sourcing, and taste profiles of snack foods to find options that genuinely deliver on their protein and calorie promises.
This guide breaks down five proven contenders that fit the bill, each chosen for their clean ingredients and measurable macros. You can trust this curated list of low-calorie high protein snacks to help you make a quick, informed choice.
How To Choose The Best Low-Calorie High Protein Snacks
Not all snacks labeled “high protein” or “low calorie” deliver on both fronts. You need to check the actual protein-per-calorie ratio, watch for hidden sugars, and consider fiber content for fullness. Here’s what to look for.
Protein to Calorie Ratio
The most effective snacks offer at least 1 gram of protein per every 10 to 12 calories. For example, an 11g protein snack at 120 calories hits a strong ratio. Anything below 8g protein for 150 calories is a weak option.
Fiber and Net Carbs
Fiber slows digestion and keeps you satisfied longer. Prioritize snacks with at least 3 to 5g of fiber per serving. Low net carbs (total carbs minus fiber) also help maintain stable energy, especially if you follow a keto or low-GI diet.
Ingredient Quality and Sourcing
Look for NON-GMO, gluten-free, and low-sodium markers if you have dietary restrictions. Plant-based protein sources like edamame and soy offer complete amino acid profiles, while bars should avoid sugar alcohols that cause bloating.

In‑Depth Reviews
1. YuBi Bars Variety Pack
YuBi stands out because of its ultra-low calorie count of just 99 per bar while still packing 10 grams of complete plant-based protein. The bar is enrobed in Rainforest Alliance chocolate, giving it a genuine candy-bar texture without the sugar crash — only 2 grams of sugar per serving.
Manufactured in a gluten-free and dairy-free facility, YuBi works for vegans, celiacs, and anyone avoiding common allergens. The variety box includes four flavors, which keeps boredom at bay. The protein comes from a blend of pea and rice protein, creating a complete amino acid profile without soy.
Because of the low calorie ceiling, the bar is on the smaller side. It works best as a between-meal pick-me-up rather than a meal replacement. The cardboard packaging is FSC certified, aligning with sustainability goals.
Why it’s great
- Lowest calorie count in the lineup at 99 per bar
- Vegan, gluten-free, and dairy-free
- Rainforest Alliance chocolate for ethical sourcing
Good to know
- Bar size is modest — not a full meal replacement
- Limited protein per bar compared to higher-calorie options
2. Healspot Edamame Beans
Healspot uses edamame grown on dedicated 3000m² farms, delivering 11g of complete plant-based protein per serving with only 120 calories. The beans are dry roasted — never fried — and use a low-salt seasoning that lets the natural nutty flavor of the soybean come through.
Each serving provides 4g of fiber and only 3g of net carbs, making it a strong keto-friendly and diabetes-friendly option. The pack includes individual 0.9oz portions, which makes portion control automatic. It’s also NON-GMO, gluten-free, grain-free, and contains zero cholesterol.
The crunch is substantial — comparable to roasted chickpeas but with a cleaner taste and less salt. These work well as a straight-from-bag snack or as a topping on salads and soups. The oil-free preparation keeps the calorie count honest.
Why it’s great
- Dry roasted, never fried — no added oils
- 11g protein with only 120 calories and 4g fiber
- Low salt formula ideal for sodium-conscious diets
Good to know
- Single flavor (sea salt) may feel limited
- Portion size is small — some may want a bigger pack
3. The Only Bean Crunchy Dry Roasted Edamame (Sea Salt)
The Only Bean delivers an identical macro profile to Healspot — 11g protein and 100 calories per pack — but with a different texture and seasoning approach. The dry roasting process gives a crisp, airy crunch that feels lighter than traditional roasted chickpeas or nuts.
With only 2g of net carbs per serving, this snack fits tightly into keto and low-GI diets. It’s also kosher certified and gluten-free, widening its appeal. The 10-count variety packs are individually wrapped, making them easy to stash in a gym bag, desk drawer, or car.
Some users note the salt level is moderate, not overpowering. The beans work well as a standalone snack or mixed into a trail mix. At 2 Weight Watchers points per pack, it’s a practical option for points-based tracking systems.
Why it’s great
- Very low net carbs — only 2g per serving
- Individual 100-calorie packs prevent overeating
- Kosher certified and gluten-free
Good to know
- Sea salt only — no flavor variety
- Small pack size may require multiple bags for fullness
4. Crispy Dunes Peanut Butter Wafer Sticks
Crispy Dunes offers a different category experience — a wafer snack that satisfies a sweet craving while staying at 80 calories per stick. Each stick contains 4g of prebiotic fiber, which supports gut health without the bloating that comes from sugar alcohols.
The peanut butter cream filling is smooth and the wafer shell stays crispy, even in humid conditions (a noted plus for reviewers in Hawaii). These are vegan, NON-GMO, and contain no artificial additives or synthetic ingredients. The two-pack format per individual wrapper lets you eat one or save the second for later.
The trade-off is protein content — at roughly 2g per stick, it’s not a high-protein snack in the traditional sense. However, as a low-calorie treat with fiber and clean ingredients, it fills a specific gap for those who need a dessert-like option without derailing macros.
Why it’s great
- Ultra-low calorie count at 80 per stick
- Prebiotic fiber supports digestion
- Vegan and free from artificial ingredients
Good to know
- Protein content is low — not a primary protein source
- Peanut butter flavor is mild per some reviewers
5. Wonderslim Fluffy Nutter Bars
Wonderslim’s Fluffy Nutter bars deliver the highest protein count in this list — 15g per bar — alongside 7g of fiber and only 160 calories. The macros make this the most filling option in the lineup, suitable for replacing a light meal or supporting post-workout recovery.
The bar is gluten-free and positioned as keto-friendly with low sugar and low carb counts. The “fluffy” texture is lighter than dense protein bars, making it easier to eat without feeling overly chewy. It’s individually wrapped and designed for on-the-go convenience.
Some users note that the sweetness level is moderate, not cloying, which helps it pair well with coffee or tea. The 7-pack format is smaller than a full month’s supply, so it’s best as a trial or supplement to a broader snack rotation.
Why it’s great
- Highest protein-to-calorie ratio at 15g for 160 calories
- 7g fiber supports digestion and fullness
- Low sugar and low carb — fits keto plans
Good to know
- 7-pack is smaller than typical bulk options
- Slightly higher calorie count than the edamame snacks
