The body’s ability to maintain muscle mass with aging is influenced by factors such as hormonal changes, decreased physical activity, and nutritional deficiencies. As one ages, levels of hormones like testosterone and growth hormone decline, which can contribute to muscle loss. A sedentary lifestyle exacerbates this issue, leading to a condition known as sarcopenia. Additionally, inadequate protein intake can hinder muscle synthesis. Engaging in regular strength training and consuming sufficient protein can counteract these effects and support muscle maintenance.
