Understanding Calories and Diet-Induced Thermogenesis

The video explores the idea of negative calorie foods, explaining that while some foods like celery are low in calories, no food actually has negative calories. The body uses energy to digest food, a process called diet-induced thermogenesis, which accounts for about 10% of daily calorie burn. Different nutrients require varying amounts of energy to digest, with protein requiring the most. Celery, despite being low in calories, still provides a net gain in calories after digestion.
