Final answer:
To reduce obesity in individuals with low income, public health efforts include promoting healthy meals, limiting unhealthy food in schools, improving access to parks, and encouraging physical activity through better urban design. Additionally, the Let's Move! campaign and behavioral weight loss interventions are pivotal in supporting these goals.
Step-by-step explanation:
The four public health efforts to reduce obesity in people with low income include promoting healthy meals, limiting access to sugary beverages and junk foods in schools, increasing access to parks, and developing pedestrian routes in urban environments. These efforts aim to reduce food energy consumption and promote energy expenditure through physical activity. Moreover, the Let's Move! campaign by First Lady Michelle Obama emphasizes involving the entire community—including parents, teachers, and healthcare providers—to ensure children have access to healthier food options and opportunities for physical activity to combat childhood obesity.
Furthermore, evidence-based behavioral recommendations suggest interventions that include self-monitoring of food intake and exercise, nutrition education, dietary changes, physical activity goals, and behavior modification strategies. These interventions are designed to help individuals achieve and maintain a significant level of weight loss, thereby reducing the risk for obesity-related diseases and improving cardiometabolic risk factors.
