On average, a person burns roughly 100 calories by walking one mile, though this can vary based on individual factors such as weight, walking speed, and terrain. Heavier individuals may burn more calories, while lighter individuals might burn slightly less. Walking is a low-impact exercise that contributes to overall caloric expenditure and supports weight management goals. It can be easily incorporated into daily routines, making it an accessible form of physical activity. Tracking these calories can also help individuals stay motivated and monitor their progress towards fitness goals.
