Weird, this drug chemically changes behaviour, so how can his behaviour stay the same?

It's been reported to reduce cravings related to food, alcohol, and cigarettes, you are saying your father while on the drug consumes the same?

Or is it that he uses it for a while, then lapses, repeat ad naseum?

If it's the second scenario, that's personal responsibility, not much to do there really, he has been given all the tools to improve but chooses not to, and that will catch up to him, no matter ozempic usage.

It is sold as a tool, not a fix. If you've found it to be otherwise you should report it to the FDA.

Did you actually see it being sold in the way you're describing, or are you just extrapolating from social media rot?

I dont really think an ancedote is a good argument. We have studies showing many people eat less on ozempic and loose substantial amounts of weight, and its main effect is not even the weight loss but reducing heart problems and fixing blood sugar in diabetes patients

He lost substantial amounts of weight. He sees it as a solution to his problem of being overweight and does nothing to change his lifestyle. I'm concerned that celebrating this drug as a simple solution to Obesity sends that message to other people as well

EDIT: celebrating Ozempic as a simple solution to obesity is literally what I'm referencing my Dad doing

You should keep in mind that you’re disapproving of your father’s lifestyle choices and his choices were not determined by the drug.

Many people make different choices on those drugs. Eg once they’ve lost some weight and it’s easier to move, they move more and the sedentary lifestyle changes. Similarly, I’ve seen antidepressants used to get enough functioning and control back that the chain of causes and effects can start to be addressed and intervened in.

Is he not eating less? If it's reducing appetite that seems like the biggest change of behavior you'd want, right?
