That's an unrealistic fix. Even if Doritos, Big Macs, and french fries were expensive, most people would still eat them for their hyperpalatability.
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.
> 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.
