Best High-Protein Snacks Under 100 Calories (2026): 9 Verified Picks With Up to 22g Protein

The efficiency king under 100 calories is the plain tuna pouch — 22g of protein for 80 calories on the verified label — and the best dairy option is nonfat Greek yogurt: 15g of protein for 90 calories in a Fage Total 0% single-serve cup. At this calorie level the honest rule is simple: the best options are lean, single-ingredient foods, because every gram of fat or sugar spends the same tiny calorie budget without buying protein. What “still filling” means under 100 calories is mostly protein density plus volume — a 70-calorie hard-boiled egg feels like food in a way a 100-calorie spoon of powder never will.

The 9 Best Picks, Broken Down

#1 Highest Protein: Bumble Bee Chunk Light Tuna Pouch (22g / 80 cal)

At 22g of protein for 80 calories, the Bumble Bee Chunk Light tuna pouch is the single most protein-efficient snack you can eat under 100 calories. The pouch format is shelf-stable for 3–5 years, requires no draining, and the Lemon & Pepper and Chipotle varieties eat well directly from the pouch without utensils. Zero carbs, zero sugar, ~280mg sodium per pouch — moderate for a protein food this dense. The honest catch: the smell limits where you can open it (skip it in an open office or on a plane). See our tuna pouch comparison for all brands and flavors.

#2 Best Dairy Pick: Fage Total 0% Plain Greek Yogurt (15g / 90 cal)

The Fage Total 0% single-serve cup (5.3 oz) delivers 15g of protein for 90 calories — one of the highest protein-per-calorie ratios of any dairy snack. Unlike yogurts sweetened with monk fruit or stevia, Fage Total 0% has only naturally occurring milk sugars (6g carbs) with zero added sweeteners. The thick, tart texture is genuinely filling because it requires chewing slightly rather than sipping. Add cinnamon and a few blueberries and you are still under 100 calories with real volume. For a full brand comparison see our Greek yogurt protein ranking.

#3 Best Shelf-Stable: Country Archer Zero Sugar Beef Jerky (12g / 70 cal per oz)

Country Archer Zero Sugar delivers 12g of protein per 1-oz serving at 70 calories with 0g of sugar from 100% grass-fed beef. Most standard jerky adds 3–6g of sugar to the marinade; Country Archer Zero Sugar eliminates that, keeping the calorie count low. Sodium runs around 350mg per oz — typical for cured meat. Available at Target, Whole Foods, and Amazon. See our full beef jerky comparison for options across all brands.

#4 Best No-Prep Pick: Hard-Boiled Egg (6g / 70 cal)

One large hard-boiled egg: 6g of complete protein, 5g of fat, 70 calories. It is the gold standard for what a filling sub-100-calorie snack looks like — it requires chewing, has real food volume, and the fat plus protein combination blunts hunger hormones more effectively than a protein drink at the same calorie count. Pre-cooked, pre-peeled hard-boiled eggs are now sold at Trader Joe’s, Costco, most grocery chains, and convenience stores. Two eggs is still only 140 calories with 12g of protein — a genuinely satisfying mini-meal. See our hard-boiled egg snack guide.

#5 Best Savory Grab: Deli Turkey Roll-Up (12g / ~60 cal for 2 oz)

Two ounces of Boar’s Head Ovengold oven-roasted turkey breast delivers about 12g of protein for approximately 60 calories. Roll two slices around a dill pickle spear and you have a 13g protein snack for roughly 70 calories in 20 seconds. The catch: requires refrigeration. The Hillshire Farm Ultra Thin sliced turkey is a consistent packaged option (about 12g protein per 2-oz serving) available at most grocery stores.

#6 Best Slow-Digesting Option: Good Culture Cottage Cheese (14g / ~82 cal per half cup)

Half a cup (113g) of Good Culture 2% cottage cheese delivers approximately 14g of protein for about 82 calories. Cottage cheese is primarily casein protein (slower-digesting than whey or Greek yogurt), which means it stays with you longer — particularly useful as a pre-bedtime snack. Good Culture uses clean cultures and minimal additives. For more options see our cottage cheese snack guide.

#7 Best Quick Grab: Sargento Natural String Cheese (7g / 70 cal per stick)

One Sargento Natural string cheese stick delivers 7g of protein at 70 calories. It is individually wrapped, does not need refrigeration for a few hours (fine in a desk drawer through a workday), and the real mozzarella format means you are getting complete milk protein rather than processed cheese product. Pair with deli turkey for a 19g protein snack under 130 calories. See our string cheese protein guide for brand comparisons.

#8 Best Volume Pick: Cooked Shrimp (18g / ~85 cal for 3 oz)

Three ounces of cooked shrimp is about 18g of protein for roughly 85 calories, with physical volume that a tuna pouch does not have. Shrimp is almost pure lean protein (under 1g fat per oz). The limitation is preparation — requires cooking or buying pre-cooked — and the smell in a shared office is similar to tuna. Fresh cocktail shrimp or frozen pre-cooked shrimp heated in 3 minutes are the easiest formats.

#9 Best Packaged Protein Bar Under 100 Calories: Think! Thin Protein Bar (20g / 100 cal)

The Think! Thin Original Chocolate Fudge bar delivers 20g of protein at exactly 100 calories — the only commonly available protein bar that squeezes this much protein under the 100-calorie ceiling without a tiny serving. It uses whey and milk protein isolate, 0g sugar (sweetened with maltitol and sucralose), and 1g net carbs. The catch: maltitol at high doses can cause GI discomfort, and one bar is the limit before that becomes a real concern. Use this for the convenience of a bar format when whole-food options are not available.

What “Filling” Means Under 100 Calories

Satiety at this budget comes from three levers, and protein is only one of them. Protein density is the strongest per calorie — it is the most satiating macronutrient and it blunts hunger hormones for hours afterward. Volume matters more than people expect: shrimp, cottage cheese, and Greek yogurt physically stretch the stomach for the same calories as two bites of cheese. Eating form is the quiet third lever — food that requires chewing (jerky, shrimp, an egg) satisfies more than food that slides down (drinks and yogurts comparably). The table’s top rows happen to combine all three.

The 100-Calorie Pack Trap

“100 calories” on the front of a package is a portion promise, not a nutrition claim — the classic 100-calorie packs of crackers and cookies deliver 1–2g of protein, meaning you spent the entire budget on the least satiating macronutrient and will be hungry again in forty minutes. The test for anything in this genre: flip to the protein line first. If the protein-per-calorie ratio is worse than an egg’s — under roughly 8g per 100 calories — it is a treat, not a protein snack, whatever the box says. The snacks that pass this test are almost always lean, single-ingredient foods: meat, plain dairy, eggs.

Pairing Two Stays Under 200 Calories

• Tuna pouch + hard-boiled egg: 28g of protein for about 150 calories — a full mini-meal. The egg adds volume and fat that the tuna alone lacks.
• String cheese + deli turkey roll-ups (2 oz): roughly 19g of protein for about 130 calories, zero preparation, fridge optional for a morning at the office.
• Greek yogurt cup + hard-boiled egg: about 21g of protein for roughly 160 calories — volume plus protein, the most filling combination on this list.
• Country Archer jerky (1 oz) + 1 hard-boiled egg: 18g of protein for about 140 calories — the most convenient shelf-stable pairing; both can live in a desk drawer.

Frequently Asked Questions

What is the highest-protein snack under 100 calories?

A plain water-packed tuna pouch: 22g of protein for 80 calories (27.5g per 100 cal). Cooked shrimp (18g / ~85 cal), Fage Total 0% Greek yogurt (15g / 90 cal), and deli turkey (12g / ~60 cal) are the runner-ups. All are lean, single-ingredient, whole foods.

Are 100-calorie snack packs good for weight loss?

Only when the 100 calories carry protein. The genre was built around crackers, cookies, and pretzels — 1–2g of protein each — which spends the budget on carbohydrates without touching hunger. Apply the egg benchmark: under about 8g of protein per 100 calories is a treat, not a protein snack.

Is 100 calories enough for a snack?

As a bridge between meals, yes. Pair two items from the list and you have a 130–180 calorie mini-meal with 20g+ protein. A tuna pouch plus a hard-boiled egg is 150 calories and 28g of protein — that qualifies as a complete, small meal.

What protein snacks under 100 calories are best for weight loss?

Lean protein sources with no added sugar and high volume per calorie. Tuna pouches, nonfat Greek yogurt, cooked shrimp, deli turkey, hard-boiled eggs, and cottage cheese all pass that test. Avoid anything with “100 calories” on the front that delivers under 8g of protein. Full guide: best high-protein snacks for weight loss.

What protein snacks under 100 calories need no refrigeration?

Tuna pouches (22g / 80 cal, shelf-stable 3–5 years), beef jerky (10–12g / 70–100 cal per oz, 12+ months), and string cheese (7g / 70 cal, fine at room temp for hours). The dairy options require refrigeration. Full shelf-stable guide: best high-protein snacks without refrigeration.

Can you hit 30g of protein from snacks all under 100 calories each?

Yes. Three items — a tuna pouch (22g / 80 cal) + a string cheese (7g / 70 cal) + a hard-boiled egg (6g / 70 cal) — gives you 35g of protein for 220 total calories across three separate under-100-calorie snacks. A meaningful contribution to a 120–160g daily protein target without powders or bars.

What about protein drinks under 100 calories?

Half a Fairlife Core Power Light is 100 cal and 15g protein — the best sub-100-cal RTD option. The honest trade-off is that drinking protein skips the chewing and physical volume that make a snack feel filling. Use a drink when convenience is paramount; use solid foods when satiety matters.

Bottom line: under 100 calories, buy lean single-ingredient proteins — tuna, shrimp, yogurt, cottage cheese, jerky, eggs, cheese — and judge every packaged “100-calorie” claim by its protein line, not its front panel. The Bumble Bee tuna pouch tops the list at 22g / 80 cal; Fage Total 0% Greek yogurt is the best dairy option at 15g / 90 cal; Country Archer Zero Sugar jerky is the best shelf-stable pick at 12g / 70 cal.
