Finding satisfying low calorie snack ideas that actually keep you full is one of the most common challenges when eating for weight loss or calorie control. The good news: dozens of whole foods come in well under 100 calories per serving — and many of them are more filling than their calorie count suggests.
This list covers 25 snacks across every food group, with verified calorie counts from USDA FoodData Central and a clear breakdown of what makes each one worth choosing. Whether you prefer sweet, savory, crunchy, or creamy, there is something here for every craving.
What Makes a Good Low-Calorie Snack?
Not all 100-calorie snacks are equal. A small bag of pretzels and a hard-boiled egg both hover around 100 calories, but only one will keep you satisfied until your next meal.
A 2016 review published in Advances in Nutrition found that snacks containing protein, fiber, and whole grains produced the greatest reductions in hunger and calorie intake at subsequent meals. The practical takeaway: prioritize snacks that combine at least two of these three qualities.
- Protein slows digestion, stabilizes blood sugar, and preserves muscle during a calorie deficit.
- Fiber adds volume and takes longer to move through the gut, extending the feeling of fullness.
- Healthy fat (in small amounts) signals satiety hormones and enhances absorption of fat-soluble vitamins.

Fruit-Based Low-Calorie Snack Ideas
Fruit is naturally low in calories and high in water, fiber, and vitamins. These five options each come in well under 100 calories per generous serving.
1. Fresh strawberries (1.5 cups) — ~70 calories Strawberries are one of the most volume-friendly fruits available. A heaping cup and a half delivers vitamin C, manganese, and 3g of fiber for roughly 70 calories.
2. Apple slices (1 medium apple) — ~80 calories Apples provide 4g of fiber per medium fruit, most of it pectin — a soluble fiber that forms a gel in the gut and slows gastric emptying. Eat with the skin on for maximum benefit.
3. Watermelon (2 cups diced) — ~85 calories At 92% water by weight, watermelon is one of the most hydrating snacks you can eat. Two full cups clock in at just 85 calories while delivering lycopene and vitamins A and C.
4. Blueberries (1 cup) — ~85 calories One cup of blueberries provides 3.6g of fiber and one of the highest antioxidant profiles of any common fruit. Their natural sweetness makes them an excellent substitute for sugary snacks.
5. Grapes (3/4 cup) — ~78 calories Grapes are portable, require no preparation, and deliver resveratrol, a polyphenol linked to cardiovascular health. Freeze them in summer for a more satisfying, sorbet-like texture.
Vegetable Snacks Under 100 Calories
Vegetables are the ultimate high-volume, low-calorie snack category. Most come in so far below 100 calories that you can eat genuinely large portions without concern.
6. Baby carrots (10 pieces) — ~35 calories Baby carrots provide beta-carotene, fiber, and a satisfying crunch for just 35 calories per standard serving. Pair with 2 tablespoons of hummus and you still stay under 100.
7. Cherry tomatoes (1 cup) — ~27 calories At 27 calories per cup, cherry tomatoes are practically a free food. They are rich in lycopene, potassium, and vitamin C. Their natural sweetness satisfies mild sugar cravings.
8. Red bell pepper strips (1 medium pepper) — ~31 calories Red bell peppers contain more vitamin C than an orange — over 150mg per medium pepper — for just 31 calories. Slice into strips and dip or eat plain.
9. Celery sticks with 1 tablespoon peanut butter — ~95 calories This classic combination pairs crunchy, high-water-content celery with a small hit of protein and healthy fat from peanut butter. The contrast in texture makes it one of the most satisfying sub-100-calorie options on this list.
10. Cucumber slices with 2 tablespoons hummus — ~80 calories Cucumber adds crunch and hydration; hummus adds plant-based protein and tahini's healthy fats. Together they deliver a balanced snack with a Mediterranean flavor profile.
High-Protein Snacks Under 100 Calories
Protein is the macronutrient most strongly associated with satiety. These snacks all deliver meaningful protein for under 100 calories — making them especially useful on days when meals feel light.
11. Hard-boiled egg (1 large) — ~63 calories A hard-boiled egg provides 6g of complete protein, choline for brain health, and all essential amino acids for just 63 calories. Prepare a batch at the start of the week for grab-and-go convenience.
12. Shelled edamame (1/2 cup) — ~95 calories Edamame delivers 8g of plant-based protein and 4g of fiber per half cup. It is one of the few plant foods that provides all essential amino acids, making it an excellent choice for vegetarians and vegans.
13. Lean deli turkey (2 oz) — ~62 calories Two ounces of low-sodium deli turkey provides approximately 10g of protein for just 62 calories. Roll slices around a piece of cucumber or bell pepper for a portable, no-prep snack.
14. Plain non-fat Greek yogurt (1/2 cup) — ~50 calories Half a cup of plain non-fat Greek yogurt delivers 6-8g of protein and beneficial probiotics for around 50 calories. Add a sprinkle of cinnamon or a few blueberries to enhance the flavor without pushing past 100 calories.
15. Part-skim string cheese (1 stick) — ~80 calories String cheese is one of the most convenient high-protein snacks available. One stick delivers 7g of protein and 15-20% of the daily value for calcium in a perfectly portioned package.
Crunchy Low-Calorie Snack Ideas
The desire for something crunchy often leads people toward chips and crackers that quickly exceed 100 calories. These options satisfy the crunch craving without the caloric cost.
16. Air-popped popcorn (3 cups) — ~90 calories Three cups is a genuinely satisfying volume of popcorn — the kind of amount that takes real time to eat. Without butter or oil, air-popped popcorn is a whole-grain, high-fiber snack for 90 calories. It is the single best calorie-per-volume snack on this list.
17. Almonds (14 nuts) — ~98 calories Fourteen almonds provide 3.5g of protein, 1.5g of fiber, magnesium, and heart-healthy monounsaturated fat. Research consistently links nut consumption to reduced hunger at subsequent meals, despite their relatively high calorie density.
18. Pistachios (20 nuts) — ~80 calories Pistachios offer a unique advantage: their shell slows eating speed. Research suggests eating in-shell pistachios reduces calorie intake compared to shelled versions because the shells serve as a visual cue of how much has been consumed.
19. Plain rice cake (1 cake) — ~35 calories A single plain rice cake is very low in calories at 35 calories, giving you room to top it with a teaspoon of nut butter or a slice of avocado and still stay comfortably under 100 calories.
20. Jicama sticks (1 cup) — ~54 calories Jicama is underused but excellent — a crisp, mildly sweet root vegetable with a texture similar to water chestnuts. One cup provides 6g of fiber and 54 calories, making it one of the highest-fiber, lowest-calorie crunchy snacks available.
Smart Combo Snacks Under 100 Calories
These pairings combine two ingredients to create snacks with a more complete nutritional profile — balancing protein, fat, and carbohydrate within the 100-calorie limit.
21. Low-fat cottage cheese (1/2 cup) — ~90 calories Half a cup of low-fat cottage cheese provides an impressive 14g of protein for approximately 90 calories. Its mild flavor works well with fruit, cracked pepper, or a drizzle of hot sauce.
22. Smoked salmon with 1 tablespoon light cream cheese — ~70 calories One ounce of smoked salmon (about 40 cal) paired with a tablespoon of light cream cheese (about 30 cal) delivers omega-3 fatty acids and protein in an elegant, satisfying combination.
23. Plain nonfat yogurt with 1/4 cup mixed berries — ~80 calories Combining 1/2 cup of nonfat yogurt with a small handful of berries creates a snack with probiotics, antioxidants, and a naturally sweet flavor — no sugar needed.
24. Rice cake with 1 teaspoon almond butter — ~68 calories One plain rice cake topped with a level teaspoon of almond butter stays around 68 calories while delivering a genuinely satisfying balance of crunch and richness.
25. Three dried apricots with six almonds — ~95 calories This pairing hits all the markers: natural sweetness, healthy fat, fiber, and iron from the apricots alongside protein and crunch from the almonds. It is one of the most portable options on the list — no refrigeration required.

ℹ️ Night Snacking Tip
If evening cravings are your biggest challenge, reach for high-protein options like cottage cheese, Greek yogurt, or a hard-boiled egg. Protein digests slowly overnight, helping prevent the overnight hunger that disrupts sleep and leads to larger breakfasts.

Tips for Making Low-Calorie Snacks Work
The best snack strategy pairs smart food choices with good habits. A few principles that research and clinical practice support:
- Plan snacks in advance. Pre-portioned snacks reduce the likelihood of grabbing whatever is convenient. Prep a week's worth on Sunday.
- Eat mindfully. Eating while distracted leads to consuming more without realizing it — a well-documented phenomenon in appetite research.
- Drink water first. Mild dehydration is frequently mistaken for hunger. A glass of water 10 minutes before a snack can reduce how much you eat.
- Match your snack to your goal. If your next meal is two hours away, a lighter 50-70 calorie snack is sufficient. If it is four hours, opt for a more substantial 90-100 calorie option with protein.

Frequently Asked Questions
What snacks are under 100 calories?
Dozens of whole foods fall under 100 calories per serving. Top options include one hard-boiled egg (63 cal), 1.5 cups of strawberries (70 cal), 3 cups of air-popped popcorn (90 cal), 1/2 cup of shelled edamame (95 cal), and 1 cup of cherry tomatoes (27 cal). The 25 snacks in this article cover every food group and flavor preference.
Are 100-calorie snacks filling enough to curb hunger?
Yes — when chosen wisely. A 2016 review in Advances in Nutrition found that snacks high in protein and fiber produced the greatest reduction in hunger before subsequent meals. A 63-calorie hard-boiled egg with 6g of protein will keep you fuller longer than a 100-calorie rice cake, even though the egg has fewer calories.
What is the healthiest low-calorie snack?
There is no single answer, but the best options combine protein, fiber, and micronutrients. Hard-boiled eggs, edamame, plain Greek yogurt, raw bell pepper strips, and low-fat cottage cheese all score well on this framework. For a deeper look at nutrient quality, see our guide on what calories really are and why food composition matters as much as calorie count.
How many snacks should I eat per day on a diet?
Most evidence-based weight loss plans include one to two planned snacks per day. The goal is to prevent extreme hunger — which reliably leads to overeating at meals — not to add unnecessary calories. If your meals are filling and well-timed, you may not need snacks at all. Listen to genuine hunger signals rather than eating by the clock.
What high-protein snacks are under 100 calories?
The best high-protein options under 100 calories include: 1/2 cup low-fat cottage cheese (90 cal, 14g protein), 1/2 cup shelled edamame (95 cal, 8g protein), 2 oz lean deli turkey (62 cal, 10g protein), one hard-boiled egg (63 cal, 6g protein), and one part-skim string cheese stick (80 cal, 7g protein). Pairing any of these with a vegetable keeps total calories low while adding fiber.
