The most effective GLP-1 drugs can generate about 25% weight loss , so if you are not severely overweight, then it is somewhat a cure. Assuming you are rich enough to afford it, are lucky enough to have a doctor who thinks treatment of less severe obesity is important, or are one of the very small percentage of people motivated and educated enough to source them illicitly, or happen to live in the US where "clinics" provide semi cheap off label versions. This assumes you respond at least as well or better than average to them, and do not have intolerable side effects and are prepared to stay on them long term.
I think over the next decade or so a huge proportion of the population is going to end up on them, once they are cheap enough and good oral versions exist, ( and cause less nausea ) mainly for risk reduction for a pile of different diseases, plus of course the cosmetic and lifestyle benefits of being less fat.
But for people with more severe obesity and especially those with syndromic/genetic obesity they are not even close to good enough yet. And still inferior to bariatric surgery. But much better than previous options. The pharmaceutical companies are intensively researching additional medications to go with them, to reduce loss of, or increase muscle mass and increase maximum weight loss.
