The calories burned calculator estimates session energy expenditure from activity, body weight, duration, intensity and terrain. It starts from a MET value, then applies adjustment factors used by the simulator. The result helps compare workouts; it should not be used to judge the value of a workout or a meal.
Calories burned = MET × body weight in kg × duration in hours; kcal/min = MET × 3.5 × weight / 200
The main formula is: kcal/min = adjusted MET × 3.5 × body weight in kg ÷ 200. Session total is kcal/min × duration in minutes, and weekly projection multiplies that session total by the number of sessions.
Example matching the default settings: moderate running at 8.3 MET, vigorous intensity, endurance goal, 72 kg and 75 minutes. Adjusted MET is about 10.3, expenditure is about 13.0 kcal/min, or 974 kcal for the session and 2,922 kcal for three weekly sessions.
The number is an estimate of energy expenditure, not an exact measurement. Two people doing the same activity may differ because of weight, movement economy, technique, fatigue, temperature, heart rate and fitness level.
A MET expresses the energy cost of an activity compared with rest. Walking, cycling, swimming and running start from different values, making comparison clearer than duration alone.
At the same MET, a heavier person usually expends more absolute energy. Duration then turns expenditure per minute into a session total.
Incline, resistance, wind, uneven surfaces and real pace can change effort. The calculator factors approximate that difference, but they remain simplified.
Multiplying one session by sessions per week gives a useful trend for comparing routines. It is not a weight-loss guarantee because diet, sleep and recovery also matter.
Connected devices use their own algorithms. They can help track a personal trend, but they should not be treated as perfect metabolic measurements.
The best activity is not always the one that burns the most per minute. Consistency, no pain, enjoyment and sustainable progression matter more for healthy practice.
A health or wellness calculator gives an order of magnitude based on general formulas. It does not replace diagnosis, medical follow-up or individual assessment, especially during pregnancy, illness, treatment or unusual symptoms. Use the number as preparation for a better-informed discussion, not as a standalone verdict.
Age, height, weight, sex, activity, cycle data or heart rate should be entered carefully. A simple input error can strongly change interpretation for energy needs, heart-rate zones or body markers.
Use the result to follow a trend rather than judge a single day. Sleep, hydration, activity and energy expenditure naturally vary; a consistent average is more useful than a conclusion from one calculation. Recheck the inputs when your routine, weight, training or objective changes.
If the result affects an important medical, nutrition or training decision, confirm it with a qualified professional. Personal context, history and goals can completely change the correct interpretation.
Test running, cycling or walking with the same weight and duration to see the effect of MET.
Lower intensity and increase duration only if recovery remains good.
Use the projection to follow a trend, not to chase calorie-level precision.
Read the estimate together with diet, sleep and overall energy balance.
This page provides an indicative estimate and does not replace personalized medical, dietetic or sports advice. If you have pain, dizziness, pregnancy, chronic disease, an eating disorder, a long inactivity period or doubts about suitable effort, consult a health professional.
The calculation uses adjusted MET, body weight and duration: kcal/min = MET × 3.5 × weight ÷ 200, then multiplies by minutes.
No. It is an estimate for comparing sessions and following a personal trend.
At similar intensity, moving a heavier body usually requires more absolute energy.
Not automatically. Exercise, hunger, recovery and body weight interact in a more complex way.
Calculate daily calories by age, height, weight, sex, activity and goal. Estimate BMR, TDEE, maintenance, weight loss, lean gain and macronutrients.
Estimate resting energy needs, compare activity levels and turn this benchmark into maintenance, weight-loss or lean-gain targets.
Calculate protein needs by weight, activity and goal. Estimate grams per day, g/kg, protein per meal, optimal range and food equivalents.
Calculate daily water needs by weight, age, activity, climate and exercise. Estimate liters per day, glasses, bottles, hourly plan and hydration tips.
Calculate target heart rate from age, resting HR, intensity and the Karvonen method. Get cardio zones, bpm, max HR, reserve HR and training tips.
Calculate BMI, identify the adult category and complete the reading with healthy weight range, waist measurement, activity and indicator limits.
