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.
- Informational only — not personalized medical or dietary advice.
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.
