Formula Transparency

Total Daily Energy Expenditure (TDEE)

TDEE = Basal Metabolic Rate (BMR) * Activity Multiplier

Calculates the total number of calories you burn daily, combining baseline resting metabolism with physical activity factors.

Variable Definitions & Glossary

BMRBasal Metabolic Rate

Resting metabolic calories burned just to keep organs functioning.

Activity MultiplierActivity Tier Factor

Multiplier based on physical active tiers, from 1.2 to 1.9.

Step-by-step educational solution

1

Basal Metabolic Rate (BMR)

1649 kcal/day
(10 * 70kg) + (6.25 * 175cm) - (5 * 30yrs) + +5

Energy burned at complete rest to sustain organ functions.

2

Activity Multiplier

1.55
Activity Level tier: moderate

Factor accounting for daily movement and exercise energy expenditure.

3

Total Daily Energy Expenditure (TDEE)

2556 kcal/day
BMR (1649) * Multiplier (1.55)

Total estimated daily caloric requirements to maintain your current weight.

How to Think About This Calculation

Understand your daily energy needs to design effective weight loss, gain, or maintenance targets.

Core methodology
  • 1.Determine baseline BMR using age, gender, height, and weight inputs.
  • 2.Select the activity level multiplier that corresponds to your lifestyle.
  • 3.Multiply BMR by the activity factor to calculate TDEE.
Professional tips
  • To lose weight safely, aim for a conservative daily deficit of 300 to 500 calories below TDEE.
  • Ensure protein intake remains high during deficits to preserve lean muscle tissue.
Common pitfalls
  • Overestimating exercise activity levels, which leading to overeating during a weight loss target.
  • Drastically cutting calories too far below BMR, which can slow metabolic rates.
Frequently asked questions

Common Questions about TDEE

What is BMR vs TDEE?
BMR is the energy your body needs at rest, while TDEE adds the additional energy expended during physical movement throughout the day.
How do I use TDEE for weight loss?
Consume fewer calories than your TDEE (typically a 500-calorie daily deficit) to stimulate fat burning.
