Total Daily Energy Expenditure (TDEE)
AI explanation
Formula
TDEE = BMR × activity multiplier, where BMR uses the Mifflin-St Jeor equationWorked example
Male, 75kg, 175cm, age 30, moderately active
| Field | Value |
|---|---|
| Weight | 75 |
| Height | 175 |
| Age | 30 |
| Sex | male |
| Activity level | moderate |
| Total Daily Energy Expenditure (TDEE) | 2633 |
Assumptions
- Activity multipliers are standard estimates (1.2 to 1.9) and may not precisely reflect your actual energy expenditure.
Frequently asked questions
What is TDEE?
Total Daily Energy Expenditure is the total number of calories you burn in a day, including your resting metabolism (BMR) plus all physical activity.
Should I eat exactly my TDEE every day?
Eating at TDEE is intended to maintain your current weight. Eating below TDEE typically results in weight loss and above TDEE in weight gain — see the Calorie Deficit and Calorie Surplus Calculators.
How accurate is TDEE from a formula like this?
It's a population-average estimate. Actual energy expenditure varies with muscle mass, genetics, and NEAT (non-exercise activity thermogenesis), so treat it as a starting point.
