3rd hand anecdote, but a friend who used Ozempic spoke to the psychological impact of seeing the cravings for food vanish that went beyond just the timeframe of the dose. A drug that effectively shuts off the compulsion helps demonstrate the disconnect between the desire and the need for food. She specifically called out that experiencing the absence of craving helped with willpower after the Ozempic dose was withdrawn.

The experience of going through one whole day with only water/tea/coffee, feeling a hole in your stomach by early afternoon and seeing the hunger subside by bed time and lasting until the next afternoon also "demonstrate the disconnect between the desire and the need for food".
