Total Daily Energy Expenditure (TDEE) Calculator
Enter your details below to calculate your estimated TDEE.
Frequently Asked Questions (FAQs) about TDEE
What is TDEE?
TDEE stands for Total Daily Energy Expenditure. It's an estimate of how many calories you burn per day, taking into account your Basal Metabolic Rate (BMR) and your activity level. It's a crucial number for anyone looking to manage their weight.
What is BMR?
BMR, or Basal Metabolic Rate, is the number of calories your body needs to perform basic, life-sustaining functions at rest.
How accurate is this calculator?
This calculator provides an estimate. The formulas used (Mifflin-St Jeor) are widely accepted, but metabolism can vary by individual.
How can I use my TDEE to achieve my goals?
- To maintain weight: Eat roughly your TDEE in calories.
- To lose weight: Eat fewer calories than your TDEE.
- To gain weight: Eat more calories than your TDEE.
In-Depth Explanation of TDEE Components
Basal Metabolic Rate (BMR)
Your BMR is the largest component of your TDEE, accounting for 60-75% of calories burned daily.
Physical Activity Level (PAL)
This accounts for exercise and non-exercise activity. Multipliers used are:
- Sedentary: BMR × 1.2
- Lightly Active: BMR × 1.375
- Moderately Active: BMR × 1.55
- Very Active: BMR × 1.725
- Extra Active: BMR × 1.9
