Fit Beats Skinny for Living Longer

People are constantly being told to watch their weight, but perhaps the advice should be watch thier muscle mass. Research recently published in The American Journal of Medicine suggests that muscle mass index serves as a better predictor of long life than weight. Most health care professionals are trained to focus on body mass index (BMI), which is a system for establishing weight norms based on weight and age. However, among older adults, BMI’s association with longevity (how long a person lives) has proven inconsistent. Among older adults, BMI may not be a great predictor of long life.

Dr. Preethi Srikanthan and his research team at UCLA think that measuring muscle mass may be a better way to evaluate health than just measuring weight. Using electrical devices called impedance meters, they were able to determine the amount of muscle each person had. They did this measurement on 3,659 individuals age 55+ and followed them to measure their lives. Dr. Srikanthan and team found a definite correlation between higher muscle mass index and longer life among retirees.

The take away message may be that we should do more than watch our calories. We need to stay active in ways that will keep our muscles in good shape.
