5 Hidden Causes of Bone Loss (#4 Is a Shock) - Dr. Douglas Lucas

Everyone on a GLP-1 is watching the scale; almost no one is watching their bones. Bone loss isn't an inevitable part of aging; it's a reversible signal that something deeper is going wrong, and it starts far earlier than most people are ever warned.In this episode, Dr. Gabrielle Lyon sits down with Dr. Douglas Lucas, a former Stanford-trained orthopedic surgeon turned bone-health specialist, to discuss:Why bone loss begins around 45 during perimenopause, not 50, and why waiting for your first DEXA scan at 65 is far too late to prevent itThe blind spots in the standard DEXA scan: a scan-to-scan margin of error near 6% and no read on bone quality, only quantityBone turnover markers (CTX and P1NP) you can test from blood to see whether you're building or breaking down bone in real timeWhy the "protein is bad for bones" and "alkalize your diet" beliefs are myths and why protein, minerals, and adequate calcium matter more than calcium aloneWhat rebuilds bone at home: resistance training, real impact like heel drops, and vertical vibration plates used ~10 minutes a dayUnderstanding your bones as a living, changeable organ system means you can catch loss early, measure it honestly, and reverse the trajectory, instead of accepting decline as your fate.Thank you to our sponsors:Head to https://bit.ly/4ftfObn and use code DRLYON for 25% off sitewide.
