> 3) How easily people lose weight on GLP-1 agonists shows that obesity isn't just lack of willpower
What? I’m about as pro-GLP1 as it gets - see past comments on the subject.
But if anything it absolutely slams the door shut on obesity about being anything but overeating when the environment made it so damn easy to do so. The method of action is you are less hungry and eat less. Full stop. Secondary effects are a rounding error.
Sure, there are societal reasons people are fat now. I don’t actually believe willpower is a real thing when surrounded by unhealthy addictive choices. But being able to turn off the hunger switch and turn to easy mode is absolutely the reason these drugs work and are life changing.
I’m not ashamed to admit my being fat was due to lack of willpower to not eat excessively. Having a way to make it so I didn’t need to engage said willpower even half as much was the reason I’m now down to 12% body fat and am in shape from working out heavily. It’s not like you take the drug and you magically get thin - you still need to work at it and make healthy choices. They simply become easier to do.
Pretending it’s otherwise for the vast majority of people is a disservice.
The best most honest way I’ve come up with to describe these drugs is a performance enhancing drug for your diet.
Changing society at a root cause level would of course be far better, but that’s not realistic on any human lifetime sort of scale. This is the best we have for people alive today.
One of the things that blew my mind when I moved to the US from Europe were the enormous portions and the amount of grease in every single dish when eating out. Even simple salads were shiny and drenched in oil. It only takes a small percentage of excessive calories over long periods to explain the obesity epidemic.
I agree with your comment, except that framing it as "lack of willpower" is unfortunate, because it implies that you should somehow be able to ignore these signals - if only you had enough "willpower". It seems to require an untenable amount of willpower to sustain a resistance to these signals, so perhaps it isn't realistic.
I think the main unhelpful thing is the implication that a lack of willpower is some kind of moral failing that means you deserve the results.
(The other fiction which causes problems is the idea that the amount of willpower required is the same for everyone)
The idea of individual locus of control is how western society has made so much progress. The idea of determinism that a certain subset of the "political left" has embraced is detrimental to the functioning of society, no matter how true it actually is. When people are not invested in their outcomes through a society-wide belief in individual control, we end up with situations like collective farming. Taken to its extreme, the idea of determinism results in "from each according to his abilities, to each according to his needs", equal outcomes for disparate effort and ability.
I eat whatever I want, don't really exercise and I'm not fat. I guess I just have awesome willpower.
