How are years of life lost related to METs expended?

The relationship between years of life lost and metabolic equivalents (METs) expended is often understood in the context of physical activity and its impact on health outcomes. When considering METs, which quantify the energy expenditure of various physical activities, higher levels of METs expended are typically associated with improved health and reduced risk of mortality. Thus, individuals who engage in higher-intensity physical activity tend to lose fewer years of life due to their healthier lifestyle choices.

The correct response focuses on the proportional relationship where an increase in METs expended correlates with better health outcomes and a decrease in the years of life lost. This association emphasizes the importance of physical activity in disease prevention and longevity. Moreover, it acknowledges that the benefits of physical activity are generally applicable across various demographics, making the connection independent of factors such as sex and weight.

This understanding highlights the critical role of increasing physical activity levels (as measured by METs) in promoting overall longevity, illustrating that higher energy expenditures typically lead to healthier life outcomes regardless of the individual's sex or weight.
