The thermic effect of food refers to the increase in energy expenditure that occurs after eating, primarily due to the energy required for digestion, absorption, and metabolism of the nutrients in food. When we consume food, our bodies expend energy to break it down and utilize the nutrients, which contributes to our overall energy expenditure. This effect can vary depending on the composition of the meal; for example, protein-rich foods typically have a higher thermic effect compared to carbohydrates and fats.

This increase in energy expenditure is essential for understanding metabolic processes, as it contributes to the total daily energy expenditure along with basal metabolic rate and physical activity. By focusing on the role of the thermic effect of food, it becomes clear why this aspect is crucial for anyone looking to understand metabolism and energy balance more comprehensively.
