Why increasing running distance may not lead to weight loss

Running is a common tool for weight management, but many athletes find that increasing distance does not automatically lead to weight loss. The effectiveness of running depends on the relationship between energy expenditure, biomechanics, and nutritional support—without these factors, monotonous movement rarely yields significant results. Energy Expenditure and Caloric Balance Calorie burn during running is determined by two primary variables: body mass and exercise intensity. On average, an individual weighing 132–154 lbs (60–70 kg) burns between 500 and 800 kcal per hour of running. A general metric for tracking expenditure is the consumption of approximately 1 kcal per kilogram of body weight for every kilometer covered. For beginners, interval walking may be more productive, as it targets fat deposits while minimizing systemic stress.
