The real conversation about GLP-1 medications doesn't end with the prescription. Part 2 is where we get into the uncomfortable truths — the data on muscle loss, the biology of weight regain, the patient safety crisis hiding in the compounding pharmacy space — and more importantly, the complete five-pillar protocol for using these drugs with a long-game mentality. If you're on these medications, considering them, or prescribing them, this episode is required listening.

Part 1 drops alongside this one — start there if you haven't.

In this episode

Why 39% of weight lost on semaglutide may be lean mass — and what that means for your longevity trajectory
The muscle-longevity math: how GLP-1-driven sarcopenia can silently trade one risk for another
Protein targets that actually matter: why the RDA is useless and what 1.6–2.4g/kg actually looks like on a plate
The leucine threshold — why hitting 25–30g per meal is the trigger for muscle protein synthesis
Resistance training as non-negotiable: the 2023 data showing body recomposition is achievable on these drugs
The five-pillar MD Longevity Lab protocol: DEXA, protein architecture, resistance training, metabolic biomarkers, and the full clinical picture
STEP 4 trial: two-thirds of lost weight regained within one year of stopping — and why that's biology, not failure
The homeostatic counter-response: ghrelin, leptin, metabolic rate suppression, and why stopping without a foundation is dangerous
Perimenopause intersection: two simultaneous catabolic forces and why nobody is connecting the dots for women
