what is one reason why the percentage of overweight teens has increased in the past 50 years

Answer 1

One significant reason for the increase in the percentage of overweight teens over the past 50 years is the rise in sedentary lifestyles, largely due to the proliferation of technology and screen time. With the increasing use of televisions, computers, and smartphones, many teens engage in less physical activity and more sedentary behaviors, contributing to weight gain. Additionally, accessible fast food and processed snacks have made unhealthy food options more common, further exacerbating the issue.
