Do you track your weight, hoping to see the numbers drop? What if the scale is deceiving you about true health, muscle, and healthy aging? Many believe they understand the keys to a vibrant later life, but conventional wisdom often overlooks a critical truth. 

This oversight could be inadvertently putting your future well-being on a slippery slope of decline, even if you feel like you're doing everything right. You might be losing something far more valuable than just fat.

In this episode, Dr. Vonda Wright, a double board-certified orthopaedic surgeon with over 20 years of clinical and research experience, joins to reveal the truth about muscle and body composition in later years. 

A best-selling author, Vonda reveals why muscle is not merely for aesthetics but a metabolic powerhouse crucial for energy, glucose control, and preventing age-related frailty. Learn how to truly 'lean up' and why it’s vastly more important than just losing pounds.
