10 foods that are basically calorie-free

Arugula

A heaping cup of leafy, green arugula (also known as rocket) clocks in at just 5 calories. Arugula is also a solid source of vitamin K, fiber, and antioxidants.

Blue Rings

Asparagus

We love grilling asparagus, which needs only olive oil (healthy!) and parmesan cheese to turn it into a savory-yet-slimming side.

Blue Rings

Bell peppers

Most bell peppers—green, yellow, red, orange—are considered sweet, but that’s not reflected in the calories. A medium-sized bell pepper, or a one-cup serving, has only about 30 calories.

Blue Rings

Broccoli

Packed with fiber, vitamin C, vitamin K, and numerous antioxidants, broccoli is also low in calories. A cup of chopped broccoli contains only 31 calories, so include it on your plate or add it in recipes as often as possible.

Blue Rings

Cabbage

Cabbage is an easy way to add some substance to your meal without adding too many calories.

Blue Rings

Cauliflower

It’s no secret why cauliflower has recently replaced things like rice, pizza crust, and buffalo wings—it’s a much healthier option. Not only is cauliflower filled with fiber and antioxidants, but it contains just 27 calories per cup.

Blue Rings

Celery

When a food is 95% water, it’s a solid sign there aren’t many calories involved. Such is the case with celery, which has only about 15 calories per cup.

Blue Rings

Chili peppers

If the bell pepper entry had you wondering about chili peppers, you’ll be delighted to know they are also very low in calories.

Blue Rings

Cucumbers

All those recipes where cucumbers are used in place of tortilla chips, crackers, or other foods is for good reason—a cup of cucumber clocks in at just 16 calories.

Blue Rings

Fennel

Although it looks like an onion, fennel is botanically in the carrot family but tastes like anise or black licorice. If that jives with you, you’re in luck, as every cup of sliced fennel has only 27 calories!
