> Obesity is a disorder of the GABA-ergic central nervous system
This is too reductive. As a person who used to be fat and lost ~20kg over a few months by eating only 1 meal/day, I cannot symphatize with people who say they cant lose weight because of their genetics or whatever because you are supposed to feel hungry when losing weight.
That said, I get that many people just cant resist that hungry feeling. However, I've seen so many people who make these arguments eat tons of ready meals, desserts loaded with sugar, giant milkshakes etc. If they were serious about losing weight they could at least eat things like cucumbers or lettuce that keep you full with minimal amount of calories ingested.
The gist of it to me seems like these drugs are for people who are willing to pay thosands of $ to feel as full as when they were eating their 5000kcal/day diet without having to endure the feeling of not eating that amount. Which, contrary to your claim, boils down to the willpower issue. These drugs let you buy your way out of the willpower requirement.
