The strongest GLP-1 meds can cause a 20-25% reduction in weight. So, for those who aren't drastically overweight, they could be considered a "cure" of sorts. That is, if you have the money to pay for it, find a doc who believes treating mild cases is worthwhile, or you're lucky enough to know how to get them on the grey market, or live somewhere they're readily available. Also assuming you respond well and don't suffer side effects and stay on them indefinitely.
I think in the next decade a large portion of the population will be on them, once they become affordable and oral versions come out (with less nausea), mostly for health reasons, but also for the cosmetic and lifestyle benefits. For those with severe obesity and genetic conditions, they aren't good enough yet, and still inferior to surgery. But much better than previous options. Drug companies are studying other meds to take in conjunction, to reduce muscle loss and increase weight loss.
