“Eating celery burns more calories than it contains”

The appealing idea of "negative calorie" foods, items that supposedly require more energy to digest than they provide, has long captivated those looking for dietary shortcuts. Among these, celery has earned a starring role, widely believed to be the ultimate example of a food that literally helps you lose weight just by eating it. This misconception likely stems from celery's extremely low-calorie count and high water content, making it a popular choice in diet plans.

However, scientific evidence doesn't quite support this enticing claim. While a single stalk of celery is indeed very low in calories, typically around 6, the energy your body expends to digest it is significantly less. The thermic effect of food (TEF), which is the energy used to process what you eat, for celery is roughly 8% of its caloric content. This means that digesting a 6-calorie stalk of celery only burns about 0.5 calories. So, while celery is an incredibly healthy and low-calorie snack, it still provides a net gain of calories, albeit a very small one.

People commonly embrace this myth because it aligns with a desire for easy weight loss solutions and seems intuitively plausible given celery's watery, fibrous nature. It's easy to imagine that all that chewing and processing of a seemingly "empty" food would expend more energy than it offers. While celery is an excellent choice for anyone looking to reduce calorie intake without sacrificing volume, it doesn't possess the magical "negative calorie" property often attributed to it.
