While celery is a very low-calorie food, it likely doesn't provide you with negative calories. Mayo Clinic suggests that while it's theoretically possible for negative-calorie foods to exist, there are no reputable scientific studies that prove certain foods cause negative calorie effects.
One stalk of celery contains only about 10 calories, while a cup of chopped celery contains about 16. It also contains dietary fiber (1.6 grams per cup), which helps curb cravings because it absorbs water in the digestive tract, making you feel fuller longer.
