The thermic effect of food is the energy required for digestion, absorption, and disposal of all the food consumed. The claims behind negative calorie food are that few food items have lesser calories than the calories needed to process it in the body. The thermic effect of certain food items is higher than the calories those food items have; This means negative calorie food creates a calorie deficit and helps in weight loss.


Let's look into one of the most popular "negative calorie food "- CELERY, which has modest 16 kcal per 100 gms and in one study where fifteen female volunteers were examined before and after consuming celery and TEF was only 2.24 kcal on average per 100 grams. Science suggests that no food can have negative calories and claims out there are have negative calories are entirely baseless.
Ofcourse, having high satiety food makes it easy to maintain a caloric deficit, but this does not mean that weight loss will happen because of that particular food item.


 For weight loss to occur, you need consistent efforts towards restricting your caloric intake, and these low calories food can only assist in limiting energy intake by keeping you full for a more extended period.
