Final answer:
To reduce the health risk of obesity, a comprehensive approach including increased physical activity and healthy eating education is necessary. Technological changes contributing to sedentary lifestyles and the cost of food affect obesity rates, requiring community-led initiatives to encourage healthier choices.
Step-by-step explanation:
It is true that in order to reduce the health risk of obesity, it is not sufficient to merely restrict children's access to junk food at school. Measures such as increased physical activity and education on healthy eating habits are essential components of a child's education to combat obesity. Environmental factors play a role in the prevalence of obesity, as technological advances promote sedentariness and food costs can affect dietary choices. Initiatives like the Let's Move! campaign by former first lady Michelle Obama emphasize the role of the community in encouraging active lifestyles and healthier food choices. Additionally, an active individual is likely to burn more calories, which is a direct factor in reducing obesity. Therefore, a comprehensive approach involving multiple strategies is imperative for effectively addressing and reducing childhood obesity.
