Sitting has a significant impact on metabolic rate during the day, as prolonged sedentary behavior tends to lower energy expenditure. When individuals sit for extended periods, their body’s metabolism slows down, which can lead to weight gain and increased risk of chronic diseases like diabetes and heart disease. The body burns fewer calories, and muscle activity decreases, reducing the overall metabolic efficiency. To counteract these effects, it is advisable to incorporate movement breaks, such as standing or walking, throughout the day to promote better metabolic health.
