Exercise calories

Calories burned during Desk work — 15 to 60 minutes

Desk work is estimated at about 1.3 METs. A 70 kg person may burn roughly 48 calories in 30 minutes or 96 calories in 60 minutes.

Estimate, not a measurement: Watches and machines can also be wrong. Use the same method consistently and avoid “eating back” every reported exercise calorie automatically.

What changes the calorie burn?

This is a low-intensity estimate. Standing, walking breaks and fidgeting can raise daily movement beyond the table.

Two people with the same body weight can burn different amounts because movement efficiency, fitness, intensity and rest time differ. MET tables describe an average energy cost, not a laboratory measurement of your session.

How the estimate is calculated

Formula: calories per minute ≈ MET × 3.5 × body weight in kg ÷ 200.

For example, multiply the calories-per-minute estimate by 30 for a half-hour session. The result is rounded because false precision would make the number look more certain than it is.

How to use Desk work in a weight-management plan

Safety and recovery

Stop and seek medical advice for chest pain, fainting, severe breathlessness or a new injury. People who are pregnant, recently inactive, recovering from surgery or managing a medical condition may need an individualized starting plan.

Method and sources

Estimates use standard MET-based calculations. Public-health guidance generally encourages adults to accumulate regular aerobic activity and muscle-strengthening activity, while recognizing that some activity is better than none. See Sources & Methodology.
