She explained that during cold weather, the body engages in distinct physiological processes.
The activation of brown fat, a distinct subset of fat tissue that burns calories more efficiently and produces heat than white fat, is one of the biggest features of this. She mentioned that cold weather running induces “thermogenesis”, a process where the body generates and maintains heat, therefore leading to the activation of brown fat. She inferred that this can contribute to weight management and metabolic health, as the increased calorie burn not only supports weight loss goals but also enhances overall metabolic efficiency. This would become an effective strategy for optimizing their metabolism and maintaining a healthy body composition. This interaction of metabolic processes demonstrated how the human body is particularly adapted to lower temperatures, emphasizing the benefits of engaging in running during the winter season.
