How Calories Are Burned During Exercise

The number of calories burned during exercise depends primarily on body weight, exercise intensity, and duration. Heavier people burn more calories performing the same activity than lighter people, because more energy is required to move more mass.

MET Values Explained

Metabolic Equivalent of Task (MET) is a standardized measure of exercise intensity. A MET of 1 = calories burned at rest.

Calories burned = MET x weight (kg) x time (hours)

MET Values for Common Activities

ActivityMETCal/hour (70 kg person)
Walking (5 km/h)3.5245
Running (10 km/h)10.0700
Cycling (20 km/h)8.0560
Swimming (moderate)6.0420
Strength training5.0350
Yoga3.0210
Jump rope11.0770

Calories Burned vs Weight Loss

To lose 0.5 kg of fat per week requires a weekly deficit of ~3,850 calories (550 calories/day). Exercise contributes, but diet has a larger impact. Running for 30 minutes at moderate pace burns ~300 calories — equivalent to one small bag of chips.

Important Notes

Calorie burn estimates from devices and formulas typically vary by 10–30%. Heart rate monitors provide better estimates than MET formulas for intense activities. Individual metabolic rates also vary significantly.

Frequently Asked Questions

MET (Metabolic Equivalent of Task) measures exercise intensity. MET 1 = resting. Running at 8 km/h = MET 8 means you burn 8 times more energy than at rest.
MET-based estimates are approximate. Actual calories burned vary by fitness level, muscle mass, temperature, and individual metabolism. Use as a general guide.
Yes. A heavier person burns more calories doing the same activity. Calories = MET × weight (kg) × time (hours).
