The thermic effect of food (TEF) for dietary fat is remarkably low, consuming only 0–3% of its energy content during digestion. This metabolic fact provides a direct answer to how many calories does it take to digest 1g of fat, showcasing its energy-efficient processing compared to other macronutrients.

The human body expends a significant amount of energy, known as the Thermic Effect of Food (TEF), to process and store the food we eat. This means that the total number of calories on a food label is not the actual net amount your body receives; some of those calories are burned just to complete the process of digestion.

On average, the human body expends roughly 10% of its total daily energy expenditure just to process and absorb the food we eat. This process, scientifically known as the Thermic Effect of Food (TEF), is the answer to how many calories does digesting food take and varies based on your meal's composition.

Did you know that your body burns approximately 10% of its total daily energy just to digest, absorb, and process the nutrients you eat? This metabolic process, known as the thermic effect of food (TEF), is the key to understanding **how many calories does it take to break down food?** and shows that not all calories are treated equally by your body.
