Best Low-Calorie Snacks Under 150 Calories That Actually Fill You Up

100-calorie snack packs were one of the biggest food marketing wins of the 2000s. They were also one of the biggest letdowns for the people who ate them. The problem wasn't the calorie count — it was that the snacks were tiny, low-protein, low-fiber, and disappeared in 90 seconds. You ate 100 calories, you were still hungry, and you ate another snack.

A snack under 150 calories can absolutely be satisfying. It just has to pull one of three levers.

The three levers

1. Volume

Fullness is partly mechanical — your stomach has stretch receptors that signal 'enough.' High-water, high-fiber foods take up more space per calorie. Popcorn, berries, raw vegetables, and broth-based soups all win on this lever.

2. Protein

Protein is the most satiating macronutrient gram-for-gram. A snack with 10g+ of protein keeps you full far longer than the same calories in carbs or fat. Cottage cheese, Greek yogurt, jerky, hard-boiled eggs, edamame.

3. Crunch (or texture variety)

Sensory satisfaction matters more than people credit. A snack that requires real chewing and gives sound feedback feels more like an event. Roasted chickpeas, raw veg with hummus, seaweed snacks, apple slices — these eat slow and feel substantial even when calories are low.

The best snacks pull two levers at once. Cottage cheese with berries = protein + volume. Hummus with carrots = protein + crunch + volume. Aim for combos.

12 specific snacks under 150 calories

Volume-forward

• 3 cups air-popped popcorn + salt: ~95 cal, 3g protein
• 1 cup mixed berries + cinnamon: ~70 cal, 4g fiber
• 1 cup baby carrots + 2 tbsp hummus: ~110 cal, 4g protein
• 1 cup miso or chicken broth + green onion: ~25 cal, fills the gap before dinner

Protein-forward

• ¾ cup low-fat cottage cheese + black pepper: ~140 cal, 22g protein
• 1 hard-boiled egg + flaky salt: ~80 cal, 6g protein

What to skip

Snacks that are all carbs, all fat, or all sweet — with no protein or volume — are the ones that disappear and leave you hunting for more 30 minutes later. The usual offenders:

• Plain rice cakes (40 cal of cardboard)
• 100-cal packs of cookies/crackers (no protein, no fiber)
• Fat-free flavored yogurts (almost as sweet as ice cream, half the protein of plain Greek)
• Granola bars marketed as 'healthy' (often 200 cal with 12g sugar)
• Smoothies as snacks — they're meals in liquid form, often 300+ cal

The build-your-own formula

If you don't want to memorize a list: pair one protein source with one volume source and skip everything else.

• Protein: Greek yogurt, cottage cheese, hard-boiled egg, turkey slice, edamame, jerky
• Volume: berries, raw veg, popcorn, apple, cucumber, broth

Two ingredients, under 150 calories, takes 60 seconds. That's the snack.
