One argument would be that Ozempic doesn't give your body any additional resources. It just triggers your body to behave in a different way. But if the changes it causes are universally good, why didn't evolution already make your body work that way?

I suppose the counterargument would be that modern life is different from the evolutionary environment, and so it's possible for a change to be beneficial now that wasn't beneficial then. But it would still be good to understand better the mechanism of the effect of Ozempic on things like addiction.

Because our bodies are delicate systems of networks, and inputs in one area can have complex/unpredictable outputs elsewhere, it seems.

Typically, if something "works", there often appear to be side effects. A free lunch is rare.
