The body adapts very quickly to repeated movements. If the walking routine looks the same every day — same pace, same route, same time — the body may stop being challenged. It slips into autopilot mode, using minimal effort for maximum repetition. This reduces the calorie burn over time.

What can be done instead? Add variety — try brisk intervals, walk uphill, or change terrains. Mixing it up nudges the metabolism out of comfort and encourages the body to burn more.
