AI Calories Burned Calculator: Measure Your Workout Energy
Every movement costs energy. Whether you are running a marathon or cleaning the house, our AI Calories Burned Calculator estimates your total energy expenditure. It uses the scientific MET (Metabolic Equivalent of Task) standard combined with AI analysis to show how your specific body weight impacts your burn rate.
Why Activity Type Matters?
Duration is only half the story. Our AI engine explains why 30 minutes of Swimming burns nearly double the calories of Walking, helping you choose the most efficient exercises for your weight loss goals.
How We Calculate
- Select your Activity (Running, Cycling, Gym, etc.).
- Enter the Duration in minutes.
- Input your Weight (Heavier bodies burn more calories per minute).
- Pro Tip: Click "Get AI Advice" to see how to fuel your body specifically for this workout intensity.
The Science of Burning Calories (METs)
How do we know how many calories you burn? We use the Compendium of Physical Activities. The core unit is the MET. One MET is the energy you spend sitting quietly.
AI Performance Analysis
Numbers are good, but context is better. Our AI Analysis interprets your calorie burn:
- Food Equivalency: "You just burned off a large banana." AI helps visualize your effort.
- Deficit Planning: AI suggests how many sessions of this activity you need per week to lose 1 lb of fat.
- Intensity Check: Helps you decide if you should increase the duration or the intensity (speed) for better results.
The Calculation Formula
The general formula used by exercise physiologists is:
Calories = (MET × Weight in kg × 3.5) ÷ 200 × Minutes
- Intensity: A higher MET value means the activity is harder (e.g., Running 8mph = 11.8 METs).
- Mass: A 200lb person burns significantly more calories than a 130lb person doing the exact same task.
Activity Comparison (Based on 1 Hour / 70kg Person)
See which exercises give you the best "Burn for your Buck".
| Activity | Intensity | Approx. Calories | Efficiency |
|---|---|---|---|
| Running (8 mph) | Vigorous | ~860 | High |
| Swimming (Freestyle) | Moderate/Hard | ~590 | High |
| Cycling (12-14 mph) | Moderate | ~560 | Medium |
| Weight Lifting | General | ~220 | Low (but builds muscle) |
| Walking (3 mph) | Light | ~230 | Low |
| Sitting / Desk Work | Resting | ~100 | Baseline |
Running vs. Walking
Walking (Low Impact)
Walking is fantastic for cardiovascular health and is sustainable for long durations. However, because the intensity is low, you need to invest more time to burn the same amount of calories as a run.
AI Tip: Add an incline (hills) to double your burn without running.
Running (High Impact)
Running is a time-efficient calorie burner. It engages more muscle groups and raises your heart rate faster. The "Afterburn Effect" (EPOC) also means you continue burning calories after you stop.
AI Tip: Even a slow jog burns significantly more than a fast walk.
Net vs. Gross Calories
This calculator shows Gross Calories (BMR + Activity). Remember, even if you stayed in bed, you would still burn calories (BMR). The "extra" calories burned specifically by the exercise are the "Net Calories."
