Total Daily Energy Expenditure (TDEE) is the total number of calories your body burns in a day, including your basal metabolic rate (BMR), physical activity, and the thermic effect of food. Knowing your TDEE helps you plan your diet for weight loss, maintenance, or muscle gain.

How is TDEE calculated?

TDEE is calculated by first determining your Basal Metabolic Rate (BMR) using the Mifflin-St Jeor equation, then multiplying it by an activity factor. The activity multiplier ranges from 1.2 for sedentary individuals to 1.9 for very active people.

What is the difference between TDEE and BMR?

BMR (Basal Metabolic Rate) is the number of calories your body needs at complete rest to maintain basic functions like breathing and circulation. TDEE includes BMR plus all additional calories burned through physical activity, exercise, and digesting food.

How do I use TDEE for weight loss?

To lose weight, eat fewer calories than your TDEE. A deficit of 500 calories per day leads to roughly 1 pound of weight loss per week. Avoid going below 1,200 calories (women) or 1,500 calories (men) without medical supervision.

How accurate is the TDEE calculation?

The Mifflin-St Jeor equation is considered the most accurate BMR prediction formula for most adults, with an accuracy of about 80-90%. However, individual factors like genetics, muscle mass, and hormones can cause variation. Use your TDEE as a starting point and adjust based on real-world results.

How often should I recalculate my TDEE?

Recalculate your TDEE whenever your weight changes by more than 5-10 pounds, your activity level changes significantly, or every 2-3 months. Huvolve can automatically track your activity data from connected wearables to help estimate your actual energy expenditure.

What is Total Daily Energy Expenditure (TDEE)?

Total Daily Energy Expenditure (TDEE) represents the total number of calories your body burns in a single day. It combines your basal metabolic rate (the energy needed for basic life functions), physical activity, and the thermic effect of food (energy used to digest meals).

Understanding your TDEE is essential for any nutrition plan. Whether you want to lose weight, build muscle, or maintain your current physique, your TDEE is the foundation for setting accurate calorie and macronutrient targets.

How TDEE is Calculated

Step 1: Calculate BMR (Mifflin-St Jeor)

Male: (10 × weight kg) + (6.25 × height cm) − (5 × age) + 5

Female: (10 × weight kg) + (6.25 × height cm) − (5 × age) − 161

Step 2: TDEE = BMR × Activity Multiplier

Activity Multipliers

LevelMultiplier

Sedentary (little/no exercise)× 1.2

Lightly active (1-3 days/week)× 1.375

Moderately active (3-5 days/week)× 1.55

Very active (6-7 days/week)× 1.725

Extremely active (athlete/physical job)× 1.9

Using TDEE for Your Goals

Weight loss: Eat 250-500 calories below your TDEE for steady, sustainable fat loss
Maintenance: Eat at your TDEE to maintain current weight
Muscle gain: Eat 250-500 calories above your TDEE to support muscle growth
