Low calorie doesn’t have to mean unsatisfying — here are the snacks that genuinely curb hunger without derailing your calorie target
Snacking gets a bad reputation in weight loss circles — and deservedly so when the snacks in question are chips, cookies, and granola bars that add 200-400 calories without meaningful satiety. But strategic snacking — choosing the right foods at the right times — can actually support weight loss by preventing the excessive hunger that leads to overeating at main meals.
The key is choosing snacks that provide maximum satiety per calorie. Here are the best options under 100 calories that genuinely work.
Should You Snack When Losing Weight?
The honest answer: it depends on the person.
Snacking helps weight loss when:
- It prevents arriving at meals ravenously hungry (which leads to overeating)
- It maintains stable blood sugar between meals
- The snacks chosen are high-satiety, low-calorie options
Snacking hurts weight loss when:
- It’s habitual rather than hunger-driven (eating out of boredom, stress, or routine)
- The snacks chosen are calorie-dense with minimal satiety
- It adds calories on top of adequate meals rather than replacing excessive hunger
The practical test: If you’re genuinely hungry between meals and a small snack prevents overeating at the next meal — snacking helps. If you’re eating snacks while full out of habit — it doesn’t.
What Makes a Good Weight Loss Snack
Protein Content
Protein is the most satiating macronutrient per calorie. A snack with 10g+ protein suppresses appetite significantly more than an equivalent-calorie carbohydrate snack. As covered in our guide to how much protein you actually need per day, adequate protein throughout the day — including at snacks — produces better overall satiety and weight loss outcomes.
Fiber Content
Fiber slows gastric emptying and feeds gut bacteria that produce satiety signals. High-fiber snacks at 100 calories are significantly more filling than low-fiber equivalents at the same calorie count.
Volume
Physical volume matters — a snack that fills the stomach provides satiety signals beyond just its calorie content. High-volume, low-calorie snacks (vegetables, certain fruits) activate stretch receptors that signal fullness regardless of calorie count.
Minimal Added Sugar
Added sugar produces a rapid blood sugar spike followed by a crash — creating more hunger within 1-2 hours than the snack prevented. The best weight loss snacks have minimal added sugar regardless of their calorie count.
The Best Weight Loss Snacks Under 100 Calories
High-Protein Snacks (Best for Satiety)
1. Hard-Boiled Egg (1 large) — 70 calories, 6g protein
The single best under-100-calorie snack for satiety per calorie. One hard-boiled egg provides a complete protein source with all essential amino acids — suppressing hunger more effectively than any carbohydrate snack at equivalent calories.
Batch cook 6-8 eggs at the start of the week — they keep in the fridge for 7 days in shell.
2. String Cheese (1 stick) — 80 calories, 7g protein
Individually portioned, portable, requiring no preparation. The protein content produces meaningful satiety for 80 calories. Choose part-skim mozzarella sticks for the best protein-to-calorie ratio.
3. Cottage Cheese (100g) — 98 calories, 11g protein
At 11g protein per 100g, cottage cheese has one of the best protein-to-calorie ratios of any food — snack or otherwise. Plain cottage cheese with a sprinkle of salt or a few cherry tomatoes is a genuinely filling under-100-calorie snack.
4. Greek Yogurt (100g plain non-fat) — 57 calories, 9g protein
100g of plain non-fat Greek yogurt at 57 calories and 9g protein — add cinnamon and a few berries and stay well under 100 calories total. One of the most satiating snack options per calorie available.
5. Turkey Roll-Up (2 slices) — 60-70 calories, 10g protein
2 slices of plain turkey breast rolled up — 60-70 calories, 10g protein. Add a mustard dip for essentially zero additional calories. The highest protein snack on this list per calorie.
6. Edamame (1/2 cup shelled) — 95 calories, 9g protein, 4g fiber
Edamame provides both protein and fiber at under 100 calories — the combination producing satiety that lasts significantly longer than either nutrient alone. Frozen edamame microwaves in 3 minutes with no preparation.
High-Fiber Vegetable Snacks (Best for Volume)
7. Baby Carrots (1 cup) — 52 calories, 3.6g fiber
52 calories for a cup of baby carrots — an enormous physical volume for negligible calorie cost. The crunch and fiber content produce meaningful satiety despite the low calorie count. Pair with 1 tablespoon hummus (25 calories) for added protein and flavor while staying under 100 calories total.
8. Cucumber Slices (1 whole cucumber) — 45 calories
An entire cucumber — sliced — provides 45 calories, significant volume, and 96% water content that contributes to hydration and physical fullness. Add salt, pepper, and a squeeze of lemon for a genuinely satisfying snack at under 50 calories.
9. Celery With 1 Tablespoon Peanut Butter — 98 calories
Celery: 16 calories. 1 tablespoon natural peanut butter: 80 calories. Combined: 96 calories with 4g protein, 1.5g fiber, and genuine satisfaction from the fat-protein-fiber combination. The crunch of celery and the richness of peanut butter make this more satisfying than its calorie count suggests.
10. Bell Pepper Strips (1 whole pepper) — 31 calories, 2.5g fiber
A whole bell pepper sliced into strips — 31 calories, 2.5g fiber, and an extraordinary vitamin C content (red peppers have 3x more vitamin C than oranges by weight). One of the lowest calorie, highest-volume snack options available.
11. Cherry Tomatoes (1 cup) — 27 calories
27 calories for a cup of cherry tomatoes — essentially free from a calorie perspective. High in lycopene, vitamin C, and water content. A handful of cherry tomatoes with a pinch of salt is a genuinely satisfying zero-effort snack.
12. Radishes (1 cup sliced) — 19 calories
19 calories for a cup of sliced radishes — the lowest calorie snack on this list. The peppery flavor and crunch provide genuine sensory satisfaction that plain water doesn’t. Add salt and lemon juice.
Fruit Snacks (Best for Sweet Cravings)
13. Apple (medium) — 95 calories, 4.4g fiber
A medium apple at 95 calories provides 4.4g of pectin fiber — one of the most effective satiety fibers available. The crunch, volume, and natural sweetness make it one of the most satisfying under-100-calorie sweet snacks. As covered in our guide to the best fruits for weight loss, apples specifically are among the most evidence-backed fruits for weight management.
14. Strawberries (1 cup) — 49 calories, 3g fiber
A whole cup of strawberries — 49 calories, 3g fiber, and one of the highest vitamin C contents of any fruit. The volume and sweetness make this one of the most satisfying low-calorie snacks for people with sweet cravings.
15. Watermelon (2 cups diced) — 92 calories
92% water content — 2 cups of diced watermelon provides significant physical volume and sweetness at 92 calories. The high water content contributes to hydration and physical fullness disproportionate to the calorie count.
16. Frozen Banana (half, sliced) — 53 calories
Half a banana, sliced and frozen — 53 calories with a creamy, ice-cream-like texture when frozen. One of the most satisfying sweet snacks for under 60 calories. Freeze banana slices in advance for a ready-to-eat sweet option.
Savory and Mixed Snacks
17. 10 Almonds — 70 calories, 2.5g protein, 1.5g fiber
10 almonds — not a full handful — provide meaningful fat, protein, and fiber at 70 calories. The portion discipline is essential: 10 almonds vs. a “handful” (often 25-30 almonds, 200+ calories) is the difference between a weight loss snack and a calorie bomb.
18. Rice Cake With Cucumber — 55-65 calories
1 plain rice cake (35 calories) topped with sliced cucumber and a pinch of salt — approximately 55-65 calories total. The crunch satisfies without meaningful calorie contribution.
19. Miso Soup (1 cup) — 35-40 calories
A cup of miso soup — instant miso paste dissolved in hot water with a few cubes of tofu — provides warmth, umami satisfaction, and modest protein at 35-40 calories. One of the most calorie-efficient savory snacks available. Hot liquid also contributes to satiety through temperature and volume.
20. Pickles (3 whole) — 15-20 calories
Pickles are essentially calorie-free — 15-20 calories for 3 whole pickles. The intense flavor and crunch provide genuine sensory satisfaction for negligible calorie cost. High in sodium — relevant for people managing blood pressure, but fine for most people as an occasional snack.
21. Seaweed Snacks (1 package) — 25-35 calories
Roasted seaweed snack packages — common in Asian grocery stores and increasingly mainstream — provide crunch, umami flavor, and negligible calories at 25-35 calories per package. A satisfying savory crunch for essentially zero calorie cost.
Snack Timing for Weight Loss
When snacking helps most:
Mid-morning (10-11am): If breakfast was early or light, a mid-morning snack prevents arriving at lunch ravenously hungry. Best options: protein-focused (egg, cottage cheese, Greek yogurt).
Mid-afternoon (3-4pm): The most common hunger window — blood sugar dips after lunch and energy declines. A protein + fiber snack here prevents the vending machine visit and dinner overeating. Best options: apple + string cheese, edamame, carrots + hummus.
Pre-workout: A small snack 30-60 minutes before exercise provides energy without heaviness. Best options: banana, apple, small amount of oats.
When to avoid snacking:
Immediately after meals: If you’re snacking within an hour of eating, it’s habit not hunger.
Late at night: As covered in our article on does eating late at night cause weight gain, late-night snacking is associated with weight gain — primarily because people are rarely genuinely hungry late at night and tend to choose calorie-dense options.
When bored or stressed: Emotional and boredom eating don’t respond to food — they require addressing the underlying emotion. Identifying whether hunger is physical or emotional is the most important skill in snack management.
The Worst “Healthy” Snacks for Weight Loss
These snacks are marketed as healthy but are calorie-dense, low-satiety traps:
Granola bars: Most contain 200-300 calories with 15-25g sugar. The “healthy” label creates permission to eat several.
Trail mix: Healthy ingredients, disastrous portions. A “serving” of trail mix is typically 1/4 cup — most people eat 3-4x this amount, adding 400-600 calories.
Dried fruit: Concentrated sugar without the water that makes whole fruit satiating. As covered in our guide to the best fruits for weight loss, dried fruit should be treated like candy.
Flavored rice cakes: Plain rice cakes are fine. Flavored varieties add sugar and sodium that encourages overconsumption.
Smoothies as snacks: Even “healthy” smoothies typically contain 300-500 calories — they’re meals, not snacks.
“Protein” bars: Most protein bars contain 200-300 calories with 15-25g sugar alongside the protein. Check labels — most don’t justify their calorie count.
Building Your Snack Rotation
Having 3-5 go-to snacks prevents decision fatigue and ensures you always have an appropriate option available.
Sample snack rotation:
Sweet craving: Apple or frozen banana slices or strawberries
Savory craving: Hard-boiled egg or turkey roll-ups or pickles + seaweed
Crunchy craving: Baby carrots + 1 tbsp hummus or celery + 1 tbsp peanut butter or bell pepper strips
Warm craving: Miso soup or hard-boiled egg with salt
Portable (desk/commute): String cheese or 10 almonds or Greek yogurt (100g)
The Bottom Line
The best weight loss snacks under 100 calories — by category:
Highest protein (best satiety): Hard-boiled egg, turkey roll-ups, cottage cheese (100g), Greek yogurt (100g), edamame
