517: Is Biohacking the New Diet Culture? What Midlife Women Need to Know About Peptides, Hormones, and Body Image with Karen Martel

What if the thing you thought was finally going to free you from a lifetime of food obsession is actually feeding the very cycle you have been trying to escape?

This week on Midlife Conversations, I sat down with hormone expert and host of The Hormone Solution podcast, Karen Martel, for one of the most unexpectedly layered conversations I have had in a long time. Karen grew up with a mother who ran a Nutrisystem weight loss center, which meant that food restriction and body scrutiny were not just things she observed but the constant backdrop of her entire childhood. That early environment contributed to years of disordered eating that followed her well into adulthood.

Today Karen helps midlife women navigate the intersection of hormones, weight, and the deeply ingrained beliefs most of us are still carrying from decades of diet culture. But this episode is not just a retrospective on the 80s and 90s fat-free era. It is about where those beliefs have quietly resurfaced in the current conversation around biohacking, GLP-1 peptides, and optimization culture.

We get into the complicated reality of GLP-1 medications: the genuine relief they can bring to women who have spent their entire lives consumed by food noise, and the very real risks when they are used without proper guidance, including muscle loss, bone loss, nutrient deficiency, and what happens when access suddenly disappears. Karen also shares something she considers one of the most underaddressed pieces of this conversation: why optimizing your hormones before or alongside peptide use can change everything.

This one challenged some of my own firmly held positions. I think it will do the same for you.
