Separately, caloric-restriction research shows a deficit alone can catabolize lean muscle alongside fat unless lean mass is otherwise preserved. The two questions intersect in published research on fat-specific energy expenditure and lean-mass retention.

Semaglutide has a half-life of roughly seven days; tirzepatide’s is roughly five. That’s why both are dosed weekly in the first place — it takes about five half-lives (five weeks for tirzepatide, closer to six for semaglutide) for the drug to build up to a steady level in the body, and roughly the same amount of time for it to clear out after the last dose. In other words, stopping a GLP-1 isn’t like flipping a switch. The appetite-suppressing effect fades out over several weeks, not overnight — the pharmacology itself is already a kind of taper. - [Péptidos 101: Qué Es Realmente un Péptido (y Cómo Llegamos Hasta Aquí)](https://portaltowellness.net/research/que-es-un-peptido/): Evidence & Research Status - [Peptide 101: What a Peptide Actually Is (and How We Got Here)](https://portaltowellness.net/research/what-is-a-peptide/): Evidence & Research Status - [GLP-1 Side Effects Data From Reddit](https://portaltowellness.net/research/glp-1-side-effects-reddit-data/): Evidence & Research Status - [Preserving Lean Mass During GLP-1 Research: What the SEMALEAN Data Showed](https://portaltowellness.net/research/preserving-lean-mass-glp-1-semalean-data/): SEMALEAN 2026 data shows how lean mass responds during GLP-1 research, and why protein and resistance activity track with muscle preservation. - [What the FDA’s July Peptide Meeting Actually Means: 5 Things Every Researcher Should Understand](https://portaltowellness.net/research/fda-peptide-meeting-what-it-actually-means/): The plain-talk companion to our July 23–24 FDA advisory meeting explainer.
