Body Composition Protocol for Women: Peptides, Growth Hormone, Protein, GLP-1s & The Complete Metabolic Reset | Her Stack Series

from Biohacking with Brittany

Your body after a baby was never a calorie problem. It is a metabolic one. In this Her Stack episode I am walking you through exactly how to restore your metabolism so body composition follows. The goal is not weight loss. The goal is metabolic restoration. Body comp is downstream. I am breaking down the four drivers that actually run body composition (insulin, thyroid, sleep, growth hormone), the four pillars to address them (nutrition, lifestyle, supplements, peptides), and the exact peptide sequencing for women. Plus my honest take on GLP-1s including semaglutide, tirzepatide, and retatrutide, where they actually fit, and why microdosing makes more sense than chasing the scale. I also share what nobody talks about. Eating less postpartum often makes body composition worse. Breastfeeding is sequencing, not failure. Growth hormone is the layer women never hear about, so they plateau and blame their age when it was a fixable signal the whole time.
