I think people's intuition is generally reliable, though. What food has the term "UPF" helped you learn is 'unhealthy', which you otherwise would have thought of as healthy?
For losing fat, "fried chicken", "chocolate cake", and "sugary drinks" are intuitively unhelpful, and "vegetables", "lean meat", "water" is more "healthy".

It's not that I didn't know that certain foods were unhealthy. The term UPF (understood to mean foods that are manufactured specifically to be hyper-palatable while otherwise lacking in nutrients) taught me the reasons why I find certain foods harder to resist than others, and consequently what foods I should focus on instead (higher protein / high fiber).
