Age significantly affects muscle preservation during weight loss, with older adults facing greater challenges than younger individuals. As people age, they naturally lose muscle mass through a process called sarcopenia, and this loss can be exacerbated during weight loss. The metabolic rate also decreases, making it harder to maintain muscle while losing fat. This highlights the importance of combining resistance training with adequate protein intake to help preserve muscle during weight loss, particularly for older adults. Understanding these age-related factors ensures that effective weight management strategies promote health and longevity.
