Description

You’ve been told that “calories in, calories out” is the holy grail , but for female runners, that formula can quietly tank your metabolism, mess with your thyroid, deplete your iron, and weaken your bones.




In this episode, Serena breaks down the science of why low-energy availability wrecks hormone balance, how chronic dieting blunts your metabolism, and what to do instead if you actually want to perform.


Check out The Knight Fit Podcast where I was a guest and talked more about hormone health!
