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.
Celery is composed of 90-95% of water, which makes it one of the less caloric vegetables. It has only 16 calories per 100 gr. and is very easy to digest. Due to the high water content, celery can hydrate the body and nourish the cells, while its anti-inflammatory properties can reduce swelling and inflammation all over the body.
