What is TDEE?

Total Daily Energy Expenditure (TDEE)

TDEE, or Total Daily Energy Expenditure, is the total number of calories you burn in a day, including all activities and exercise. It represents your total energy needs to maintain your current weight.

How is TDEE Calculated?

TDEE is calculated by multiplying your BMR (Basal Metabolic Rate) by an activity factor:

TDEE = BMR × Activity Factor

Activity factors typically range from 1.2 (sedentary) to 2.0 (very active).

Activity Levels

• Sedentary: Little to no exercise, desk job (BMR × 1.2)
• Lightly active: Light exercise 1-3 days/week (BMR × 1.375)
• Moderately active: Moderate exercise 3-5 days/week (BMR × 1.55)
• Very active: Hard exercise 6-7 days/week (BMR × 1.725)
• Extremely active: Very hard exercise, physical job (BMR × 1.9)

TDEE is crucial for weight management. To lose weight, consume fewer calories than your TDEE. To gain weight, consume more.
