@Springflowers2 AIs like ChatGPT are definitely not something that is fully reliable. They can include invented information, wrong information, information that's not in the sources that they reference. As you've experienced, how you ask a question makes a difference, along with how you respond to the each of its responses. The thing to remember is that contrary to the name, there is no actual intelligence to AI, not in the sense that we usually use it to mean. It is just a computer program which produces output according to its current set up. It's attempting to "learn" by improving the output based on the responses that it gets.
An AI should also be telling you to speak to your medical provider alongside any information or advice it comes up with.
The thing about Mounjaro, Wegovy etc is that they were invented and designed to help people lose weight not maintain weight loss. So the goal is to produce 5% of starting weight or more weight loss. Mounjaro is excellent at that! But, there really won't have been much consideration as to what people do once they've lost the weight. That wasn't part of the clinical trials done to get it approved.
Now that people have been using them for a while, people are now starting to think about what maintenance is and how that might work. There's no one answer, which is why it can seem confusing and contradictory. I think that each one of us will decide on what we would like to try which might be very different, depending on lots of different things. Someone who has never been morbidly obese, or who hasn't been obese for their whole life might make different choices to someone like me who has never been a healthy weight and had been morbidly obese for a long time. I definitely need to use Mounjaro as necessary to keep my weight stable for a decent amount of time before I try to manage without medication. Once I am at goal, I will move down doses slowly and see how I adjust. Hopefully at some point I will be able to stop altogether but I am not in a rush to do that.
