The thermic effect refers to the number of calories the body burns while digesting, absorbing, and metabolizing food. This energy expenditure is part of the total daily energy expenditure and can vary depending on the type and amount of food consumed. Foods high in protein typically have a higher thermic effect compared to fats and carbohydrates, meaning more energy is required to process them.
Understanding the thermic effect is important for managing weight and overall health. It contributes to the total calories burned each day, influencing weight maintenance and loss. When people consume a balanced diet that includes higher protein foods, they may find it easier to manage their weight since their bodies burn more calories during digestion.
In the body, the thermic effect functions by increasing metabolic rate temporarily after eating. This process involves various physiological activities, such as enzyme production and nutrient transportation, that require energy. The thermic effect is generally estimated to account for about 10% of daily calorie expenditure, although this can vary based on individual metabolism and dietary choices.
In summary, the thermic effect plays a significant role in how our bodies process food and manage energy. By being aware of how different foods impact energy expenditure, individuals can make informed choices about their diets to support their health goals.
