alt Hacker NewsPlease don't harangue people about exercise and diet on HN. Everyone has heard it countless times here and elsewhere. Obviously, many people find that approach doesn't (easily) work. Yes, it's well known GLP-1s can have negative effects. Many people still find them beneficial anyway, and many people take measures to address the negative effects. None of this is simple or easy, so please stop making it out like it should be a simple or easy decision for people to just do as you suggest.
In HN guidelines terms, these sections are relevant:
Be kind. Don't be snarky. Converse curiously; don't cross-examine. Edit out swipes.
Comments should get more thoughtful and substantive, not less, as a topic gets more divisive.
Eschew flamebait. Avoid generic tangents. Omit internet tropes.
Please don't post shallow dismissals, especially of other people's work. A good critical comment teaches us something.
Pushing drugs to people who can crash your appetite is much more dangerous than promoting exercise and diet to sedentary people.
Getting 20 kg overweight only requires a 100 kcal surplus over a period of 4 years.
That's not proof that diet and exercise are not working, and it doesn't prove you need GLP-1s to resist an extra 100 kcal a day. Two slices of bread have 130 kcal for comparison.
