On social media there seem to be two types of deniers:
1. People who make stuff up about it. Even Peter Attia said in an interview recently that you lose more lean mass than fat on the drug.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8089287/ "Greater weight loss was associated with greater improvement in body composition (lean body mass:fat mass ratio)."
2. People who think it's an unfair shortcut to lose weight with a pill. That fatties should just have to exist until they can make the identity level genetic changes on their own to lose it.
Both cases are sad to see especially if you've been someone who has- or watched a loved one- struggle to lose weight their whole life.
