Do Negative-Calorie Foods Exist?

The video explores the concept of calories as energy stored in food and how our bodies use calories to process food. It debunks the myth of negative calorie foods, explaining that no known foods, including celery, have negative calories. The process of digesting food, known as diet-induced thermogenesis, uses energy but not enough to offset the calories gained from eating. The video details how different nutrients require varying amounts of energy to digest, with protein requiring the most. Celery is highlighted as a low-calorie food, but it cannot negate the calories from high-calorie foods like chocolate cake. The video concludes by emphasizing the importance of maintaining an energy balance between calories consumed and burned.
