Right, there already are some on the market like Wegovy (1). But they're expensive AFAICT and seem to have lots of side effects. Hopefully as we get better with synthetic proteins we can create more targeted treatments with less side effects. Also, many types of foods and additives also manipulate appetite. So while the article is true, there's still huge variability in the body's appetite response. Eating "less" can backfire in subconscious ways of re-adding extra calories in other hidden ways.
Long term (centuries), as a species I suspect we may end up doing some light genetic modifications to tune our appetite for norms in modern civilization. Presuming modern western style lifestyles become more sustainable.
We're less than ~100 years into this crazy modern era where routine famines aren't the norm. Even in Western Europe post-WWI and post-WWII there were lots of famines. If you compare Western Europe with the USA-minus-1.5 decades you get similar curves of obesity increase [2]. That makes sense if you consider that post-WWII it took Western Europe about a decade or two to repair basic infrastructure. The whole bit of overall Europe having healthier cuisine than the US isn't true, with regards to obesity at least. It's largely seems to be availability of calories. Eastern Europe for example reflects the fall of the USSR and economic stagnation during 1990's pretty well too [3].
