What changes the calorie burn?
Body weight, pace, technique, slope, resistance, rest time and fitness level can all change the real energy cost. MET values are averages, so the number is best used for planning rather than precision.
How to use Swimming moderate in a weight-management plan
- Choose a frequency you can repeat consistently.
- Increase time, pace or resistance gradually.
- Do not automatically eat back every exercise calorie if fat loss is the goal.
- Use weekly trends in body weight, waist and fitness, not one workout number.
- Balance activity with sleep, recovery and enough protein.

Why are calorie-burn estimates different across watches and calculators?
Different tools use different assumptions for METs, heart rate, body size, efficiency and intensity. Treat every result as an estimate, not a precise measurement.
