Mess with the fundamental hormonal balance honed over the eons of hunger and survival? What could go wrong?
There are legitimate criticisms to be made of GLP agonists, but this isn't one of them.
How about instead we fix the problem by making healthy foods and active lifestyles cheaper and more prevalent?
Good luck with that.
Unhealthy habits and diets are popular (and delicious), and a lot of people resented even the minimal effort required to wear a mask during a pandemic of an airborne disease.
The only "fix" is to ban these foods, perform public executions of food company executives, institute mandatory kcal rationing, and bring back relentless fat shaming and discrimination.
Personally, I prefer not living in a totalitarian dictatorship, so GLP-1 agonists seem like a slightly more humane option to me.
