Why aren’t you losing weight, even when you’re eating well, exercising, taking hormones, or using a GLP-1? If the scale will not budge, stubborn belly fat keeps returning, or your cravings and energy feel impossible to control, cortisol may be blocking your progress.

In this solo episode of hol+, Dr. Taz explains how chronic stress and disrupted cortisol patterns affect your metabolism.
