PMOS, formerly known as PCOS, recently underwent a landmark name change after a global consensus process involving patients, clinicians, researchers and health organizations. This episode is about much more than the recent rebrand. We explore what PMOS actually is, why the previous name created confusion, how insulin resistance and metabolic health fit into the picture, and what current evidence says about management options ranging from lifestyle interventions to medications, and what it all means for women’s health. This is perfect for anyone living with PMOS, supporting someone who is or simply interested in understanding one of the most common yet misunderstood endocrine conditions affecting women.

What if understanding macronutrients could make nutrition feel way less confusing?
A lot of us hear terms like calories, protein, carbs and fats and only consider macronutrients in the form of “tracking macros” all the time. Rarely do we learn what important roles all macronutrients play in our bodies. So instead, we end up fearing food groups, obsessing over numbers, or feeling like we’re constantly eating “wrong” without fully understanding why.
If you’ve ever felt guilty for eating carbs, scared of fats, confused by calories or overwhelmed by constantly tracking numbers, this episode is for you.
