Your Total Daily Energy Expenditure (TDEE) is the number of calories you burn daily, accounting for your basal metabolic rate and activity level. Knowing your TDEE is essential for effective weight management and fitness planning.
Basal Metabolic Rate (BMR) represents the calories your body needs at complete rest to maintain:
BMR accounts for 60-75% of total daily calorie expenditure for most people.
Your TDEE is calculated by multiplying your BMR by an activity factor:
Goal | Calorie Adjustment | Expected Weekly Change |
---|---|---|
Weight Loss | TDEE - 500 kcal | 0.5kg (1lb) loss |
Weight Maintenance | TDEE ± 0 kcal | No change |
Muscle Gain | TDEE + 300-500 kcal | 0.25-0.5kg (0.5-1lb) gain |
Muscle tissue burns more calories at rest than fat tissue. Two people at the same weight can have different BMRs:
Daily movements like fidgeting, standing, and walking account for 15-50% of TDEE:
Your body adjusts metabolism in response to calorie changes:
Maximize calorie burn through:
Nutrition choices that may increase energy expenditure:
Other ways to support healthy metabolism:
Population | Average TDEE (kcal) | Key Characteristics |
---|---|---|
Sedentary Adults | 1,800-2,200 | Office jobs, minimal exercise |
Recreational Athletes | 2,400-2,800 | 3-5 workouts/week |
Endurance Athletes | 3,000-4,000+ | High training volumes |
Strength Athletes | 2,800-3,500 | High muscle mass |
As you lose weight, your TDEE decreases. You may need to recalculate periodically or increase activity.
Gradually increasing calories after a deficit can help restore metabolism without rapid fat regain.
Your body may resist significant changes from its "preferred" weight range through metabolic adjustments.
Fitness trackers estimate calorie burn but can be 15-25% inaccurate. Best for tracking trends.
Tracking intake against weight changes provides the most accurate personal TDEE data over time.
VO2 max tests and DEXA scans provide precise measurements but are expensive and less accessible.
