Losing weight is hard. Maintaining weight is easier, except that you have to do it forever. It was incredibly hard and took me a long time to lose 15 pounds as a always had been skinny person whose weight slowly crept up. I've never been obese and I'm sure it's super challenging to change, considering how hard loosing 15 lbs was for me. But if I were, I do think I'd try a GLP-1 agonist to get my weight down.
That second part makes it harder. Losing weight was pretty simple for me, but maintaining that low weight was much harder. Someone said that it takes about half a year to form a habit. I maintained lower weight for about a year, then it came back.
