The Truth About Negative Calorie Foods And Weight Loss
What The Negative Calorie Effect Means: The term “negative calorie foods” describes foods that supposedly burn more calories during digestion than they provide. Common examples often mentioned include celery, lettuce, cucumbers, and grapefruit. The idea suggests that eating these foods leads to automatic weight loss because the body uses more energy to digest them than they contain. While this concept is popular in diet culture, scientific research does not fully support the claim. Digestion does require energy. This process is called the thermic effect of food. However, the number of calories burned during digestion is usually small compared to the calories in the food itself.
