Question 1

How many calories does walking burn?

Accepted Answer

A brisk walk burns roughly 3.5–4 calories per minute for a 70 kg person, so a 30-minute walk burns about 100–120 calories. Heavier people burn more, and faster pace or incline increases burn. Our calculator uses MET (metabolic equivalent) values for each activity to give a personalised estimate.

Question 2

How are calories burned during exercise calculated?

Accepted Answer

We use MET (Metabolic Equivalent of Task) values, which represent the energy cost of activities relative to resting. The formula is: calories burned = MET × weight(kg) × duration(hours). Each activity — running, cycling, swimming, HIIT — has a validated MET value from the Compendium of Physical Activities.

Question 3

Which exercise burns the most calories?

Accepted Answer

High-intensity activities like running, HIIT, and swimming at a vigorous pace burn the most calories per minute. However, the best exercise for you is one you enjoy and can sustain consistently. A mix of cardiovascular and resistance training is ideal for overall health and body composition.

Question 4

How accurate are calorie burn estimates?

Accepted Answer

MET-based estimates are reasonably accurate for groups but can vary by 10–20% for individuals due to fitness level, efficiency of movement, body composition, and environmental factors. Fitness trackers that measure heart rate can improve accuracy but are still estimates. Use these numbers as a guide, not an exact count.
