The number of calories burned while walking varies based on factors like weight, speed, and terrain. On average, an adult man burns approximately 0.04 to 0.06 calories per step. Therefore, for 1000 steps, an approximate calorie burn would be:
- **Low estimate**: 1000 steps × 0.04 calories/step = 40 calories
- **High estimate**: 1000 steps × 0.06 calories/step = 60 calories
So, an adult man may burn roughly between 40 and 60 calories by
