How accurate is the calorie burn calculator?

The calculator uses the MET (Metabolic Equivalent of Task) formula, which is the standard method used by exercise scientists. Real-world burn varies by 10-20% based on age, fitness level, terrain, and other factors.

MET stands for Metabolic Equivalent of Task. One MET is the energy cost of sitting quietly. An activity with a MET of 8 burns 8 times the calories of sitting. MET values are standardized by the Compendium of Physical Activities.

Do heavier people burn more calories?

Yes. The MET formula multiplies by body weight, so a 200 lb person running for 30 minutes burns roughly twice as many calories as a 100 lb person running the same time at the same pace.

Does intensity matter?

Yes. Sprinting has a higher MET than jogging, and vigorous cycling burns more per minute than casual cycling. The intensity selector adjusts the MET value up or down by 15-30%.

📌 5 Tips to Maximize Calorie Burn

✓ Add intensity intervals. Alternating 30 sec sprint + 90 sec easy jog burns more in less time than steady-state cardio.
✓ Build muscle with strength training. Muscle tissue burns more calories at rest — every pound of muscle adds ~6-10 cal/day to your BMR.
✓ Don't rely on the number alone. Heart rate variability, sleep quality, and recovery are equally important for fitness progress.
✓ Combine cardio + weights. A 30-min circuit alternating kettlebell swings and burpees burns 40% more than steady cardio at the same perceived effort.
✓ Track trends, not single sessions. Your watch may say 320 cal, the real number is anywhere from 250-400. Focus on weekly averages.
