It's a hormone-like anti-diabetes drug that's gotten popular as an off-label weight loss drug due to advertising and celebrity endorsements. It's absurdly expensive and administered via injection.
Weight control is all about calories, to lose weight you have to enter a calorie deficit (consume more than your intake) to gain weight you have to enter a calorie superavit (consume less than your intake). Your daily calorie baseline can be measure and it varies on current weight/activities/metabolism/etc... No drug will save you from that.
Committing to eating whole foods instead of trash helps adhering to a calorie deficit, too. All that fiber and protein fills you up a lot more than sugar.
Food deserts, junk food addiction, high calorie low fiber foods being cheap and easy to acquire compared to cooking your own meals, etc etc. if being thin and healthy was easy, there wouldn't be an obesity epidemic.
I don't get why people always get so defensive about this topic on hexbear. Literally no one called it easy, the people you're replying to simply said that the science is proven and that no drug is going to magically help you lose weight if you're eating more calories than you're burning
People don't eat out of some logical conclusion they reached that they need to eat a certain amount of calories
People eat because they're hungry, people eat too much because the food that is available to them and that is advertised to them isn't as filling (and a lot of the time due to bad habits that form, emotional eating, etc)
Someone being obese is not an issue of them knowing or not knowing that eating a surplus of calories is what increases weight, so this fact is irrelevant, everyone knows eating more makes you gain weight.
So, a drug that makes you eat less is something that magically helps you lose weights, because it solves something lower on the chain (being hungry), going even lower to the source would be eating better food, fixing bad habits and becoming healthier in other ways, but those are difficult non-magical solutions, taking a pill or an injection is much more of a magical solution.
Ozempic is the main reason Denmark isn't currently in a recession. it's made by Novo Nordisk, the biggest company in Denmark and also one of the biggest in Europe. It technically was developed as some type of diabetes medication and then was discovered to help people lose a LOT of weight very quickly.
