This literature review examines the growing problem of obesity in the aging population, particularly in the US. It explores the health risks associated with geriatric obesity and investigates the mechanisms linking obesity and aging. The review focuses on weight loss interventions for older adults (aged 65+), aiming to identify healthy lifestyle approaches for weight management. It references studies on calorie restriction, exercise, and the role of gut microbiota, including the use of probiotics like Lactobacillus. The review also considers the impact of Ginkgo biloba on cognitive function in older adults and analyzes data from the National Health and Nutrition Examination Surveys (NHANES) to assess obesity prevalence. The findings emphasize the importance of physical activity and healthy lifestyle choices for improving metabolic health, reducing cardiovascular risks, and enhancing cognitive function in older adults. The review concludes by highlighting the benefits of weight loss interventions and the need for a comprehensive approach to geriatric obesity management, considering factors like bone health, cognitive state, and overall quality of life.
