Exercise calorie burn is calculated using MET (Metabolic Equivalent of Task): Calories = MET × weight(kg) × duration(hours). MET 1.0 = resting; brisk walk ≈ 3.5 MET; running at 6 mph ≈ 9.8 MET. Values are sourced from the Compendium of Physical Activities (Ainsworth et al.). Heavier individuals burn proportionally more calories for the same activity. EPOC (excess post-exercise oxygen consumption) from HIIT or heavy lifting elevates metabolism for 12–48 hours post-workout, adding 50–200 extra calories burned beyond the session itself.

MET stands for Metabolic Equivalent of Task. It's a unit that expresses how much energy an activity requires relative to sitting quietly at rest. Sitting at rest has a MET value of 1.0 — any activity above that burns more calories proportionally.
The MET concept was developed by Dr. William Bortz and refined through the Compendium of Physical Activities (Barbara Ainsworth, 1993), which catalogued hundreds of activities with standardized MET values.
The formula is straightforward: Calories/min = MET × Weight(kg) × 3.5 ÷ 200. This means a heavier person burns more calories doing the same activity at the same intensity — because they move more mass.
Example: 70kg person jogging (MET 7.0) for 30 minutes:
Accuracy Note: MET-based calculations have a typical error of ±10–20%. For higher accuracy, use heart rate monitoring or metabolic testing (VO2 max).
| Category | MET Range | kcal/hr (70kg) | Examples |
|---|---|---|---|
| Sedentary | 1.0–1.5 | 70–100 kcal | Sitting, watching TV, reading |
| Light | 1.6–2.9 | 110–200 kcal | Slow walking, cooking, office work |
| Moderate | 3.0–5.9 | 210–410 kcal | Brisk walking, cycling, yoga, swimming |
| Vigorous | 6.0–8.9 | 420–620 kcal | Jogging, aerobics, sports, lap swimming |
| Very Vigorous | 9.0+ | 630+ kcal | Sprint running, competitive cycling, boxing |

Total daily calorie expenditure is much more than just formal exercise. Understanding the components of TDEE helps you maximize total calorie burn — not just during workouts.
All the calories burned during everyday movements that aren't formal exercise: walking between rooms, fidgeting, typing, standing, stair climbing.
NEAT can vary by up to 2,000 kcal/day between sedentary and active individuals.
Calories burned during intentional, structured exercise: gym workouts, running, cycling, sports. This is what most people focus on — but it's often only 5–10% of total daily energy expenditure.
EAT averages 300–600 kcal for a typical 45-60 min workout.
Higher intensity multiplies calorie burn dramatically. Running at 8mph burns roughly 60% more than running at 5mph. HIIT (High-Intensity Interval Training) can also produce an afterburn effect (EPOC) for hours post-exercise.
Doubling duration doubles calorie burn (linear relationship). Adding just 10–15 minutes to each workout session creates a meaningful weekly deficit over time. Aim for 150–300 minutes of moderate activity per week (WHO guidelines).
Muscle tissue burns ~3x more calories at rest than fat tissue. Building muscle through resistance training raises your BMR permanently — 5 kg of added muscle can burn an extra 250–350 kcal/day even at rest.

You can out-exercise a bad diet
Exercise burns far fewer calories than most people believe. A 30-min run burns ~300 kcal — undone easily by one large soda or a slice of cake. Calorie intake reduction is more efficient for weight loss than exercise alone.
Cardio is the best exercise for burning calories
While cardio burns more calories during exercise, strength training raises your BMR, meaning you burn more calories 24/7. For total energy expenditure, resistance training combined with moderate cardio outperforms cardio alone.
Fitness trackers accurately measure calorie burn
Consumer wearables have 20–50% error rates for calorie expenditure. They are useful for trends and relative comparisons but should not be used as exact numbers for adjusting diet intake.
Sweating more means burning more calories
Sweat is your body cooling itself — it has no direct relationship to calorie burn. You can sweat heavily in a sauna without significant calorie expenditure, while cool-weather running burns high calories with little sweat.
