in europe there is a social stigma around GLP-1 drugs, a lot of people considered it cheating and lazy, so a lot of people don't dare talk about their usage
The social stigma in Europe exists, because these drugs are in limited supply. So, if a person who does not really need them is using them, the people who actually need them to stay alive might have difficulty accessing them.
You also forget it is expensive and in many cases not taking charge by the respective healthcare autority of the country, so it leads to less consumption.
There may be, but I haven't seen anyone lose significant weight either since this started.
In Austria I have noticed a massive social stigma. I think that's embarrassing and backwards. As someone who is very athletic and takes nothing extraordinary besides creatine and whey protein I fully support anyone who wants to become healthier, with or without medication.
I read this online, I don't know where it was, so I can't give a source, it probably was on twitter:
"People really want these things - exercise, weight - to be important moral objectives for others, when they're not that important in the grand scheme of things. Now you'll just have to find another easy visual marker for ranking people by moral superiority."
