How Many Calories Do I Burn a Day?
The number of calories you burn depends on your Basal Metabolic Rate (BMR) and activity level.
| Activity Level | Women | Men |
|---|---|---|
| Sedentary | 1,600–1,800 cal/day | 2,000–2,200 cal/day |

Calorie Calculator – Harris-Benedict Equation
To calculate your personal daily calorie needs, use the Harris-Benedict equation:
BMR = 655 + (9.6 × weight in kg) + (1.8 × height in cm) − (4.7 × age)
For Men:
BMR = 66 + (13.7 × weight in kg) + (5 × height in cm) − (6.8 × age)
Then multiply your BMR by your activity multiplier:
| Activity Level | Multiplier |
|---|---|
| Sedentary (little/no exercise) | × 1.2 |
| Lightly active (1–3 days/week) | × 1.375 |
| Moderately active (3–5 days/week) | × 1.55 |
| Very active (6–7 days/week) | × 1.725 |
| Extremely active (athlete) | × 1.9 |
