There is no scientific evidence to show that any of these foods have a negative calorific impact. Celery has a thermic effect of around 8%, much less than the 100% or more required for a food to have ``negative calories''. A stalk of celery provides 6 calories to the body, but the body expends only half of a calorie digesting it. Even proteins, which require the most energy to digest, have a thermic energy of only 20%--30%.
