📐 Formula
💡 Practical Example
75 kg person running (MET 8.0) for 45 minutes: Calories = 8.0 × 75 × 0.75 = 450 kcal. Per minute: 450 ÷ 45 = 10.0 kcal/min.
📖 About Calories Burned During Exercise Calculator
The MET (Metabolic Equivalent of Task) system quantifies the energy cost of activities relative to resting metabolic rate. MET 1.0 = resting; MET 8.0 = running at 8 km/h.
To use the Calories Burned During Exercise Calculator, enter your Body Weight, Exercise / Activity Type, Exercise Duration. The calculator instantly computes Total Calories Burned, Calories Burned per Minute and more. Results update in real time as you change any input — no submit button needed.
How to Use This Calculator
Enter your Body Weight (e.g. 75 in kg), Exercise / Activity Type — select from Running (8 km/h) — MET 8.0, Walking (5 km/h) — MET 3.5, Cycling (moderate) — MET 6.0, and Exercise Duration (e.g. 45 in minutes). Results update instantly — no submit button needed. Use metric or imperial units as labeled. For the most accurate result, measure height and weight in the morning without shoes.
The Formula
Calories Burned = MET × Weight (kg) × Duration (hours)
MET (Metabolic Equivalent of Task) varies by activity intensity
Worked Example
75 kg person running (MET 8.0) for 45 minutes: Calories = 8.0 × 75 × 0.75 = 450 kcal. Per minute: 450 ÷ 45 = 10.0 kcal/min.
Understanding Your Result
Your BMR is the calories burned at complete rest — your TDEE (Total Daily Energy Expenditure) adds activity. To lose 1 lb/week, create a 500 kcal/day deficit. To lose 2 lbs/week, a 1,000 kcal/day deficit is required — this is generally the safe maximum recommended by clinicians. Below 1,200 kcal/day for women or 1,500 kcal/day for men risks metabolic adaptation and nutrient deficiencies. Protein intake of 1.6–2.2 g/kg body weight preserves muscle during a caloric deficit.
💡 Expert Health Guidance & Clinical Context
- This calculator uses clinically validated formulas and population reference data published by the WHO and NIH. Results are screening estimates, not medical diagnoses.
- Consult a licensed healthcare provider before making any changes to diet, medication, or exercise based on these results — individual variation is significant.
- Genetics, chronic conditions, and concurrent medications can dramatically affect what a "normal" result means for a specific individual.
- Track your results over time: a single data point is less meaningful than a trend measured consistently across multiple weeks or months.
- The CDC recommends adults receive routine health screenings at least annually. Use these calculations to prepare informed questions for your physician.
- Body composition, lifestyle factors, and stress levels all interact with the metrics shown here. No single number captures your full health picture.
- For pediatric or geriatric populations, reference ranges may differ significantly from the adult standards used in general calculators.
- Always cross-reference results with laboratory tests, clinical examinations, and professional medical evaluation before acting on any finding.
