Total Daily Energy Expenditure

Definition

Total Daily Energy Expenditure (TDEE) is the total number of calories your body needs in a day to perform all activities, from basic functions like breathing to exercise.

Scientific / Technical Definition

Total Daily Energy Expenditure (TDEE) is the overall sum of energy necessary for maintaining body homeostasis and performing physical activities throughout a 24-hour period. It is calculated as the sum of the Basal Metabolic Rate (BMR), the energy expended in physical activity, and the Thermic Effect of Food (TEF).

Benefits

• Helps determine the appropriate caloric intake for maintaining, losing, or gaining weight.
• Assists in formulating personalized diet and exercise plans.
• Improves understanding of energy balance and metabolism.

Examples

• An individual with a sedentary lifestyle might have a TDEE of 1800 calories.
• An athlete's TDEE could be as high as 3000 calories or more, depending on their activity level.

Additional Information

• importance: Understanding your TDEE is crucial for creating effective dietary and fitness plans tailored to personal health goals.
