"GLP medications blunt your appetite so you eat less, but you still end up feeling completely drained because your body lacks fuel."

How many people report that? Not that many, AFAIK.

"GLP drugs cannot distinguish between nutrient-dense meals and the junk food binges you are trying to avoid."

This again goes against what people report - aversion to junk food so strong that McDonalds et al. consider this a potential threat to their business model.
