Description
In this episode, Angela sits down with endocrinologist Dr. Rocio Salas-Whalen, MD to break down the biggest myths around GLP-1 medications, midlife weight gain, and perimenopause - and to explain how women can protect muscle, metabolism, and long-term health.
Rocio explains how oestrogen decline and stress drive visceral belly fat, why you can have a normal BMI yet high visceral fat and low muscle, and why body composition matters far more than the scales. She also clarifies who GLP-1s are truly for, why microdosing “for wellness” is unsafe, and how to use these medications without losing muscle or bone.
They also explore the psychological side of lifelong food noise, binge eating, and why GLP-1s can make sustainable lifestyle change finally feel possible.
