I felt the same after watching a similar video on another medication in the class. It listed many improvements beyond weight change. The information is already discussed in older threads if you search. Still, I keep wondering whether the drug itself creates those gains or whether the weight drop is responsible and the drug is only the tool that makes the drop possible. Designing a study to separate the two looks unrealistic. One group would have to eat exactly as if they were on the drug without taking it, which would require locked inpatient conditions. The reverse would require people on the drug to keep eating normally. Non-responders also complicate the picture because the drug produces little change for them.
A new video laid out the established positive effects tied to GLP-1 drugs, especially one specific version. The list of real advantages caught me off guard. People who have followed this longer may already know the details, but I had not seen them laid out that way before.
