What are some consequences of a sedentary lifestyle?

A sedentary lifestyle is characterized by prolonged periods of physical inactivity, which can lead to significant negative health outcomes. Choosing the option regarding a higher risk of chronic diseases and obesity captures the essence of the consequences tied to inactivity.

When individuals lead a sedentary lifestyle, their bodies do not engage in regular physical activity, which is essential for maintaining a healthy weight and metabolic function. This lack of activity can contribute to weight gain, as calories consumed are not expended through exercise. Over time, this can elevate the risk of developing chronic diseases such as heart disease, type 2 diabetes, and certain cancers. The body's ability to regulate blood sugar and cholesterol levels can diminish, leading to more severe health issues.

In contrast, the other choices represent outcomes that are typically associated with an active lifestyle rather than a sedentary one. For instance, increased flexibility and endurance, enhanced social interactions, and improved mental health are benefits that arise from engaging in regular physical activity. Thus, option B accurately reflects the consequences of inactivity, emphasizing the importance of movement for overall health.
