This review highlights the need for effective strategies to treat complications related to aging and obesity in older adults with obesity. Calorie restriction is effective in reducing fat mass, but exercise, including both aerobic and resistance training, is crucial for improving functional outcomes and preventing muscle and bone loss. When combined with testosterone therapy, lifestyle intervention can preserve muscle and bone mass in older adults with obesity and hypogonadism. Overall, a comprehensive lifestyle intervention involving calorie restriction and exercise provides the greatest improvements in health outcomes and quality of life.
Purpose of reviewAlong with the marked increase in the population of older adults with obesity is the need for effective strategies to treat aging- and obesity-related complications. This review highlights recent progress in obesity management in older adults.Recent findingsAlthough calorie restriction is needed to significantly reduce fat mass, an exercise protocol is crucial to ameliorate functional outcomes. The addition of a resistance exercise protocol improves the response of muscle protein synthesis to anabolic stimuli, preventing the calorie restriction-induced reduction in muscle and bone mass. The addition of an aerobic exercise protocol improves cardiorespiratory fitness and cognitive function. However, the addition of both aerobic and resistance exercise protocols to calorie restriction provides the greatest improvements in myocellular quality, frailty, and cardiometabolic and cognitive outcomes, translating into the greatest improvement in quality of life. Such comprehensive lifestyle intervention effectively improves glucometabolic control and age-relevant outcomes in older adults with diabetes. When combined with testosterone therapy, such lifestyle intervention also preserves muscle and bone mass in older, men with obesity and hypogonadism.We conclude that calorie restriction among older adults with obesity should be prescribed in combination with both aerobic and resistance exercise to maximize benefits on overall health.
