Any weight shaming show, like Supersize vs Superskinny, Secret Eaters etc.
Here in the US these shows have to be framed in a positive light with motivational moments like the trainer hugging a crying fatty after they confess their pet died when they were 12 and that drove them to cakes.
None of that shite in the UK, just lingering close ups on glistening fatty chests and hairy sweaty parts with a patronizing voiceover.
Great motivation for cardio sessions
