Calories Burned Calculator
Estimate calories burned during workouts, sports, daily activities, walking, running, cycling, and more.
Educational estimate only — individual calorie burn varies with fitness, terrain, and metabolism. Not medical advice.
MET (metabolic equivalent of task) for Walking (moderate, 3 mph): 3.5
How this tool calculates
Calories burned = MET × weight (kg) × duration (h). MET values come from the Ainsworth Compendium of Physical Activities (2011) — the same reference used by clinical exercise physiologists.
Pick an activity, enter your weight, and we'll estimate calories burned.
How Calorie Burning Works
Every movement your body makes — from blinking to sprinting — requires energy, measured in kilocalories (kcal, often just "calories"). Your total daily energy expenditure is the sum of three things: your basal metabolic rate (BMR), the calories burned digesting food (the thermic effect), and the calories burned through physical activity.
This calculator estimates just the third bucket: the calories you burn doing a specific activity for a specific time. It uses your body weight and the intensity of the activity, because heavier bodies need more energy to move, and harder activities demand more oxygen per minute.
MET Values Explained
MET stands for metabolic equivalent of task. One MET equals the energy you burn sitting still — about 1 kcal per kilogram of body weight per hour. An activity rated 5 METs burns five times as much energy as resting, minute for minute.
Light · 1.6–3 MET
Slow walking, stretching, light housework, yoga. Great for recovery and longevity, modest fat burn per minute.
Moderate · 3–6 MET
Brisk walking, casual cycling, doubles tennis. The CDC's target zone for general health — 150 min/week is the guideline.
Vigorous · 6+ MET
Running, HIIT, soccer, fast cycling. Builds cardio fitness and drives strong calorie burn — 75 min/week meets WHO targets.

Best Exercises for Fat Loss
The best exercise for fat loss is the one you'll actually do three or four times a week for the next six months. That said, certain modalities deliver more calorie burn per minute than others:
Running at a moderate pace
9–10 MET — top of the list for absolute calories burned per minute. Low equipment, scalable from jog to race pace.
HIIT and CrossFit
8 MET during work, but elevated post-exercise oxygen consumption (EPOC) keeps your burn higher for hours after.
Cycling (moderate to vigorous)
8–12 MET. Low joint impact, sustainable for 60–90 minute sessions — ideal for higher-volume weekly burn.
Swimming
6–10 MET. Whole-body, joint-friendly, and uniquely effective for very overweight or injured trainees.
Heavy resistance training
5–6 MET during the session, but lean-mass gains raise your resting metabolism — a long-game fat-loss lever.
Brisk hill walking
6 MET. Easy to add to a normal day, low injury risk, and adds meaningful weekly calorie burn for almost anyone.
Walking vs Running: Calories Burned
For the same distance, running burns about 30–50% more calories than walking. A 70 kg (155 lb) adult walking one mile at 3 mph burns roughly 85 kcal; running the same mile at 6 mph burns around 115 kcal. The difference grows with body weight and intensity.
For the same time, running clearly wins — you simply cover more ground and demand more oxygen per minute. Walking still shines for sustainability, recovery and joint-friendly volume. Mixing both across a week tends to outperform an all-running plan for most amateur trainees.
Daily Calorie Deficit Strategies
One pound of body fat stores roughly 3,500 kcal of usable energy (one kilogram stores about 7,700 kcal). To lose half a kilo per week, you need a sustained daily deficit of around 500–550 kcal — achieved by some combination of eating less and moving more.
Research consistently shows that nutrition does most of the heavy lifting for fat loss, while exercise excels at preserving lean mass, improving insulin sensitivity and protecting cardiovascular health during a cut. A pragmatic split: roughly 70% deficit from food, 30% from activity. That keeps you full enough to comply and strong enough to keep training hard.
