5. Age-Related Changes: The Ticking Clock of Insulin Sensitivity
As we age, our body undergoes various changes, and insulin sensitivity is no exception. This chapter delves into the age-related factors contributing to insulin resistance, exploring how the ticking clock of time influences our metabolic health. It’s a journey through the different stages of life, observing how age impacts insulin function.
One of the key aspects is the natural decline in muscle mass as we age. Muscle is critical for glucose metabolism, and a reduction in muscle mass can lead to decreased insulin sensitivity. Additionally, aging is often accompanied by an increase in abdominal fat, a known risk factor for insulin resistance.
But age-related insulin resistance isn’t just about body composition. It also involves changes in hormone levels, such as decreases in growth hormone and sex hormones, which can affect insulin sensitivity. Moreover, the aging pancreas may not function as efficiently, impacting insulin production and regulation.
What’s remarkable is the resilience of the human body. Despite these age-related changes, adopting healthy lifestyle choices can significantly mitigate the risk of insulin resistance. This chapter not only acknowledges the challenges of aging but also highlights the potential for maintaining metabolic health through proactive steps, regardless of age. (5)
