TDEE (Total Daily Energy Expenditure) is an estimate of how many calories you burn each day, including all activities. BMR (Basal Metabolic Rate) is the number of calories your body needs at rest to maintain basic functions. These values are estimates and can vary based on factors like age, gender, activity level, and body composition.

What Is TDEE and Why It Matters
TDEE (Total Daily Energy Expenditure) represents the total number of calories your body burns in a day, including basic bodily functions and physical activity. Knowing your TDEE helps you manage weight, plan diets, and optimize fitness goals.
How Is TDEE Calculated?
First, your Basal Metabolic Rate (BMR) is calculated using your weight, height, age, and gender. This value is then multiplied by an activity factor to estimate your total daily calorie burn.
Common Activity Levels Explained
- Sedentary: Little or no exercise
- Lightly active: Light exercise 1–3 days per week
- Moderately active: Moderate exercise 3–5 days per week
- Very active: Intense exercise most days
How to Use Your TDEE
- Weight loss: Eat 300–500 kcal below your TDEE
- Weight maintenance: Eat roughly at your TDEE
- Muscle gain: Eat 250–500 kcal above your TDEE
Frequently Asked Questions
Q: Is TDEE accurate?
A: It is an estimate. Individual metabolism and body composition can cause variation.
Q: Should I recalculate my TDEE?
A: Yes, especially after significant weight or activity changes.
