*and quite possibly a badly worded question intended to steer you to the wrong answer
I also think it’s significant that the headline, “When somebody loses weight, where does the fat go?“, is slightly different to the actual question asked, “When somebody loses weight, where does it go?”
I think if you asked 50 cyclist mechanics what the recommended chain stretch limit is, more of them would say 0.5% than would point out that chains don’t stretch, it’s the internal bearing surfaces wearing out.
I wouldn’t take that as proof that they don’t know their job.
It would be interesting to see this done again with a properly worded question, like “When somebody loses weight, where do the fat molecules go?”, but it would probably be hard to find 50 doctors, dieticians and personal trainers who haven’t heard about this now and would have the correct answer ready.
