What is your favorite low-calorie snack?

Does air popped corn count as low calorie? If not, it's gherkins for me

Carrots cut into thin planks to scoop home made salsa verde

I like flavored nori. This sort of thing:

Never had that particular brand, but you get the idea.

Frozen grapes. Once they've been out of the freezer for a couple minutes, they thaw into little slushie bubbles.

sugar snap peas go crazy, and they're very filling too

Fridge cold honeydew melon. Nothing even closely compares to how tasty that is for me. Low in calories as well.

Carrots. Plain carrots. It helps that I'm too lazy to get anything to dip them in. They are just so convenient.

I eat grape tomatoes, pickles, sliced cucumbers or radish with salt.

Apples for me; they're cheap, sweet, filling, and last pretty long compared to other fruit and veg.

Roasted salted pumpkin seeds

I'm a slut for potatoes. If you don't soak them in oil, butter, or cheese they're about a kcal/gram. I like to nuke one and just add salt

Sliced bell peppers.

Pickles.

Rice crackers.

Popcorn.

Sometimes I'll have celery by itself, but usually I put peanut butter on it.

Cucumber! Or red bell pepper

Veggies for dipping in hummus. Carrots, broccoli, cauliflower, mushroom. I can eat a huge bowl and barely hit 200 calories.

Four molecules of Nutella.

Carrots, raw carrots, no salt no nothing, just carrots

Ooo thanks for reminding me to get more pickles! I like pickles, but also clementines or cold grapes.

Raw potato that's cut into the shape of steak fries/chips for easy eating. Most people dislike the bitter flavour but I love the crunch and taste!

Baby cucumbers.

Freeze dried fruit

I like popsicles because they are light in that they don't feel like I'm filling my stomach, which is an issue I have related to a chronic condition. They may not necessarily be low-calorie, but they take a while to consume, which may help if the point is to delay consumption enough to pass a craving. I usually grab normal ones, but they have sugar-free ones that may reduce the calorie count.

I do ham and cheese full fibre toasties. About 150-200kcal but very filling. Not having any 'bad' snacks immediately available in the house also helps a lot.
