As public health policy though, just telling people to do the things you describe doesn't work because dieting sucks and your body doesn't want you to do it. Some people can do it but they're usually not among the huge percentage of obese people in the population. With GLP-1 agonists it doesn't even feel like you're fighting your body because you just automatically don't want to eat too much (just like people who don't have problems managing their weight). I think it's basically a good thing that modern day civilization has cheap and available calories because no one has to go hungry, but this is an environment that evolution just hasn't prepared us for and many many people are just not calibrated right for it. Maybe we can finally fix that.
