A sedentary lifestyle can lead to decreased metabolism and several negative health outcomes. Prolonged inactivity burns fewer calories, which can contribute to weight gain and an increased risk of obesity. Additionally, a lack of movement can impair glucose regulation and elevate cholesterol levels, leading to a greater risk of developing chronic diseases such as heart disease and type 2 diabetes. Furthermore, the metabolic slowdown associated with a sedentary lifestyle can lead to diminished muscle mass and strength. Encouraging regular physical activity is crucial to counteract these adverse effects on metabolism.
