Preserving Muscle Mass on a GLP-1: What Clinicians Should Recommend
Following the May 2026 JMIR data on lean mass loss during GLP-1 treatment, here's a more detailed clinical breakdown of what clinicians should actually be recommending to address it.
The specific clinical recommendations
- Protein intake targets: Higher relative protein intake during caloric deficit is associated with better lean mass preservation — a specific, actionable target clinicians can recommend rather than general "eat protein" advice.
- Resistance training, not just cardio: Resistance exercise specifically, rather than cardiovascular exercise alone, is the intervention most associated with muscle preservation during weight loss.
- Rate of weight loss: Extremely rapid weight loss is associated with proportionally higher lean mass loss — a consideration in dose titration pace for patients losing weight unusually quickly.
Clinical takeaway: This should be a proactive conversation at the start of treatment, not a reactive one after lean mass loss is already apparent. Clinicians should set protein and activity expectations as part of initial treatment planning, not as an afterthought.

What patients should proactively ask
Ask your prescriber for specific protein intake targets and whether resistance training is part of your treatment plan discussion — this shouldn't require you to bring outside research to the conversation; it should be a standard part of initial treatment planning.
