Let's Move! is the program initiated to combat childhood obesity by encouraging healthy nutrition and active lifestyles, involving the whole community and focusing on reducing sedentary behaviors.
Step-by-step explanation:
The voluntary nutrition and wellness program that aims to encourage daily physical activity, nutrition education, and the consumption of nutritious foods to combat obesity in children is called Let's Move! Initiated by former First Lady Michelle Obama, the program's goal is to involve the entire community—including parents, teachers, and healthcare providers—to ensure children have access to healthier foods and engage in more physical activity.
