20 Low-Calorie Snacks That Actually Keep You Full

Snacking can either support your diet or sabotage it — the difference comes down to what you choose. The worst snacks are those that deliver a lot of calories with little satiety, leaving you hungry again within minutes. The best snacks provide a satisfying combination of protein, fiber, or healthy fats that keeps you full between meals without blowing your calorie budget.

Here are 20 snacks under 150 calories each that actually work.

Protein-Rich Snacks

Hard-boiled egg contains about 78 calories with 6 grams of protein. It is one of the most portable and satisfying snacks available. Prep a batch on Sunday and grab one whenever you need a quick bite.

Greek yogurt (non-fat, plain, 3/4 cup) provides roughly 100 calories and 15 grams of protein. Add a few berries or a drizzle of honey if you need sweetness — just account for the extra calories.

String cheese (one stick) offers about 80 calories and 7 grams of protein. It is pre-portioned and requires zero preparation.

Turkey roll-ups (4 slices with mustard) contain approximately 80 to 100 calories and 12 grams of protein. Roll the turkey around pickle spears or cucumber sticks for added crunch.

Cottage cheese (1/2 cup, low-fat) provides roughly 90 calories and 12 grams of protein. It pairs well with fruit, cherry tomatoes, or a sprinkle of everything bagel seasoning.

Beef or turkey jerky (1 ounce) contains about 80 to 100 calories and 9 to 12 grams of protein. Choose low-sodium varieties when possible.

Fiber-Rich Snacks

Apple with 1 tablespoon of peanut butter totals roughly 145 calories. The fiber from the apple and fat from the peanut butter create a combination that satisfies both your sweet tooth and your hunger.

Baby carrots with 2 tablespoons of hummus provide about 100 calories with 3 grams of fiber. The crunch and creaminess together make this snack feel more substantial than its calorie count suggests.

Air-popped popcorn (3 cups) contains approximately 90 calories and 3 grams of fiber. It is surprisingly low in calories for its volume, making it one of the best snacks for people who like to eat a lot.

One medium banana provides about 105 calories with 3 grams of fiber and natural sugars for quick energy. Bananas are also rich in potassium.

Mixed berries (1 cup of strawberries, blueberries, raspberries) total roughly 60 to 85 calories with up to 4 grams of fiber and high vitamin C content.

Celery sticks with 1 tablespoon of almond butter come in at about 110 calories. The celery is nearly calorie-free, so you are essentially snacking on almond butter with a crunchy vehicle.

Balanced Snacks

Almonds (14 almonds, about 1 ounce portion) provide approximately 100 calories with 4 grams of protein and healthy monounsaturated fats. Measure your portion — almonds are calorie-dense and easy to overeat.

Edamame (1/2 cup, shelled) contains roughly 95 calories with 8 grams of protein and 4 grams of fiber. Available frozen in most grocery stores, it takes minutes to prepare.

Rice cake with 1/2 avocado mash totals about 120 to 140 calories. Add a pinch of salt, red pepper flakes, or everything bagel seasoning for flavor.

Dark chocolate (one square, 70% cacao or higher) contains approximately 50 to 60 calories. When you need something sweet, a single square of quality dark chocolate can satisfy the craving without leading to a binge.

Cucumber slices with 2 tablespoons of tzatziki provide roughly 50 to 70 calories. This is one of the lowest-calorie snacks on the list and is surprisingly refreshing.

One medium orange offers about 62 calories with 3 grams of fiber and a full day's worth of vitamin C. The act of peeling an orange also slows you down, which helps with mindful eating.

Frozen grapes (1 cup) contain approximately 62 calories. Freezing transforms regular grapes into a candy-like treat that takes longer to eat.

Mini bell peppers (3) with 2 tablespoons of cream cheese (light) total about 100 calories. Sweet, crunchy, and creamy — this combination checks all the boxes.

Why These Snacks Work

Every snack on this list shares one or more of these qualities: they contain protein, which is the most filling macronutrient per calorie; they contain fiber, which slows digestion and extends satiety; they have volume, meaning they take up physical space in your stomach, which sends fullness signals to your brain; or they require effort to eat (peeling, chewing, assembly), which slows down consumption and improves satisfaction.
