Which organization provides guidelines for physical activity to maintain a healthy weight?

The correct answer refers to the organization known for providing guidelines related to physical activity and its relationship to maintaining a healthy weight. PAGA, or the Physical Activity Guidelines Advisory Committee, specifically focuses on developing recommendations for physical activity across various age groups. The guidelines include information on the amount and types of physical activity necessary for health benefits and weight management.

PAGA's guidelines are based on extensive research and are intended to help individuals understand how much physical activity they need to engage in to promote health and reduce the risk of chronic diseases. They emphasize not just the quantity of exercise but also different types of activities that can contribute to an active lifestyle, which is particularly important for maintaining a healthy weight.

Other organizations mentioned in the question, such as the AHA (American Heart Association) and CDC (Centers for Disease Control and Prevention), also provide valuable information regarding physical activity and health; however, they may not focus solely on the guidelines for maintaining a healthy weight as directly and comprehensively as PAGA does. Therefore, PAGA is the most relevant organization for this specific context of promoting healthy weight through physical activity guidelines.
