Diet-Induced Thermogenesis

Definition

Diet-Induced Thermogenesis is the process by which your body uses energy to digest, absorb, and process the nutrients you eat, contributing to the total calories burned each day.

Scientific / Technical Definition

Diet-Induced Thermogenesis (DIT), also known as the thermic effect of food (TEF), refers to the increase in metabolic rate after ingestion of a meal. It accounts for the energy expended above the basal metabolic rate during the processes of digesting, absorbing, metabolizing, and storing the nutrients found in food.

Benefits

Increases daily energy expenditure.
Can aid in weight management by burning calories.
Enhances metabolism efficiency.

Examples

Consuming protein-rich foods like chicken or legumes has a higher thermogenic effect than carbohydrates or fats.
Eating a mixed meal with protein, carbohydrates, and fats results in increased energy expenditure for digestion and absorption.

Additional Information

Importance: Diet-Induced Thermogenesis is important for maintaining energy balance and supporting metabolic processes. It varies with the composition of the meal and individual factors such as age, physical fitness, and metabolic health.
