What does TDEE stand for?

TDEE stands for Total Daily Energy Expenditure. It represents the total amount of energy (calories) your body burns in 24 hours including all metabolic functions and physical movement.

What activity level should I select?

Select Sedentary if you work an office desk job with minimal intentional walks. Select Lightly Active for standing/walking and 1-3 workouts a week. Moderately Active is for 3-5 high-intensity training sessions. Very Active is for 6-7 daily training sessions.

How is TDEE used for weight management?

To maintain weight, consume your TDEE. To lose weight, eat in a caloric deficit (e.g., TDEE - 500 kcal). To gain muscle mass, consume a calorie surplus (e.g., TDEE + 300 kcal).

Mathematical Formula & Variables

Equation ModelTDEE = BMR * Activity Multiplier

Your Total Daily Energy Expenditure is computed by scaling your Basal Metabolic Rate (BMR) by a physical activity constant representing daily movement.

Variable Definitions

BMR	Basal Metabolic Rate calories (using Mifflin-St Jeor)
Activity Multiplier	A coefficient ranging from 1.2 (sedentary) to 1.9 (extremely active)

Practical Example Calculation

Scenario Context: Calculating TDEE for a 25-year-old male, 180 lbs, 5'11" height, who exercises moderately (3-5 days/week).

Step 1: Calculate BMR using Mifflin-St Jeor: BMR = (10 * 81.65kg) + (6.25 * 180.34cm) - (5 * 25) + 5 = 1,823 kcal.

Step 2: Identify physical activity multiplier: Moderate active = 1.55.

Step 3: Multiply BMR by multiplier: 1,823 * 1.55 = 2,826.

The daily maintenance requirement (TDEE) is 2,826 calories.
