Honest limits
What this study does not prove.
The findings are limited to this study design and do not establish medication safety. Strength, food intake, and function should be monitored with clinician oversight.
Kris's practical takeaway
Here's what to do with it.
Rapid weight loss deserves strength and protein support, but evidence does not show that GLP-1 use automatically destroys muscle.
Ways to use it
Safe ways to apply it.
Do not panic, measure function
Muscle protection is still a behavior plan
The scale is not the only GLP-1 metric
