Claim guardrail
What this page should prevent.
Do not generalize beyond the study design or make medication-safety claims. Keep advice focused on monitoring strength, intake, and function with clinician oversight.
Geebs coaching takeaway
The study only matters if it changes a behavior.

Content angles

Do not panic, measure function
Muscle protection is still a behavior plan
The scale is not the only GLP-1 metric
