Sarcopenia is the gradual, age-related loss of muscle mass and strength that quietly increases your risk of falls, disability, and chronic disease — and most people don't know they have it until it's already progressing. In this episode from The Optimal Body Podcast, Dr. Jen & Dr. Dom, two Doctors of Physical Therapy, break down what sarcopenia actually is, how common it is across different age groups, and why it's not just a normal part of aging.
We dig into the factors that accelerate muscle loss beyond the aging process itself, including sedentary lifestyle habits, hormonal changes like menopause and declining testosterone, and poor nutrition. We also cover why sarcopenia is closely linked to insulin sensitivity, type 2 diabetes, hypertension, and obesity, and why catching it early matters for long-term health.
The conversation focuses heavily on resistance training as the most effective, research-backed intervention for preventing and even reversing muscle loss, along with practical guidance on exercise programming, functional movement, and the importance of supervision for older adults doing strength training. We also talk nutrition — protein, vitamin D, and omega-3 fatty acids — and when it makes sense to work with a registered dietitian or nutritionist.
In this video:
- What sarcopenia is and how it's diagnosed
- Why muscle loss increases falls risk and chronic disease risk
- Hormonal and lifestyle factors that speed up muscle loss
