Calories by Body Weight

Body WeightCalories Burned

Calorie estimates are based on MET values from the Compendium of Physical Activities. Actual calories burned vary based on intensity, fitness level, and individual metabolism.

What Are MET Values?

MET stands for Metabolic Equivalent of Task — a unit that measures the energy cost of physical activity. One MET equals the energy you burn at complete rest, roughly 1 kcal per kilogram of body weight per hour.

A MET value of 5.0 means that activity burns 5 times more calories than resting. The higher the MET, the more intense the exercise. Walking has a MET of ~3.5, while jump rope reaches 12.3 — meaning it burns about 3.5× more calories than walking.

MET values come from the Compendium of Physical Activities, a research-based database maintained by Arizona State University. They represent averages across the population — your actual burn depends on fitness level, body composition, and effort.

Scale reference: Sitting quietly = 1.0 MET. Walking at 5 km/h = 3.5 MET. Running at 10 km/h = 10 MET. That means running burns roughly 10× more energy than sitting — but only while you're doing it.

How to Burn More Calories

  • Increase intensity: Switching from walking (3.5 MET) to jogging (8.3 MET) more than doubles your calorie burn for the same duration.
  • Add intervals: Alternating high-intensity bursts with recovery periods (HIIT) keeps your heart rate elevated and increases total burn.
  • Build muscle: Strength training raises your resting metabolic rate. More muscle means more calories burned even at rest.
  • Extend duration gradually: Adding 10 minutes to your workout can add 50–100+ extra calories depending on the activity.
  • Try compound movements: Exercises that engage multiple muscle groups (squats, burpees, rowing) burn more than isolation exercises.
  • Stay consistent: Burning 300 kcal per session × 5 days/week = 1,500 kcal weekly deficit, equivalent to ~0.2 kg of fat loss per week.
  • Don't forget NEAT: Non-Exercise Activity Thermogenesis (walking, fidgeting, taking stairs) can account for 200–500 kcal/day — often more than a single workout.
The NEAT factor: Dr. James Levine's research at Mayo Clinic found that NEAT (Non-Exercise Activity Thermogenesis) — fidgeting, walking, standing, taking stairs — can vary by up to 2,000 kcal/day between people. Small movements throughout the day often outpace a single gym session.
