No. The way GLP-1 drugs work is by lifestyle changes. People on GLP-1 agonists will, on average, eat smaller portions, are more inclined to eat healthier food, and will even exercise more.
If you take GLP-1s and don't do the lifestyle changes, they don't work. So are these drugs useless? No. They make the lifestyle changes more attainable. In your smoking example, it's similar. We have cessation drugs, I know because I've used them. No, they don't magically make you stop smoking. But they do make it easier.
We need to rewrite how we view these drugs. They don't take away your power, your strength. No, they help you find it. You had the strength all along, but these are tools to help you exercise it.
