I live in the US. If those numbers are true, then it seems likely that I know at least one person on it. I however don't know that I know someone one it, since people (at least in the US) don't usually announce "Hi everybody, I'm taking weight loss drugs." Being overweight is seen as shameful, and losing weight through any means other than diet and exercise is an admission of failure.

The best part is feeling the judgement from someone who thinks taking GLP1s is a moral failure when they are carrying an extra 50+ pounds themselves. I have met many people who seem to believe that being fat is actually the higher moral ground than using medication to help solve it. And these are religious people, too! Don't they know about gluttony?
