The provided sources are from the same outlet and focus on fitness guidance rather than new reporting. They argue that simply running more miles does not automatically lead to fat loss, including around the midsection. The articles state that progress can stall if training is not paired with adequate recovery, sleep, and nutrition. The guidance emphasizes that runners may need to adjust beyond mileage to see changes in body fat and abdominal appearance. The discussion also frames the issue as common among middle-aged men, presenting “dad-belly” as a pattern that may persist even in people who run regularly. Overall, the sources present the same core message: effective fat loss depends not only on exercise volume, but also on how the body recovers and how energy intake and recovery habits support training outcomes.
