No, that’s the correct interpretation, essentially we’ve simplified the “formula” to be easily digested (ci/co) and people have a tendency to understand it as an easy cut calories or expend more. But as you’ve noted, it’s extremely complex and doesn’t take into account individual needs or variability which makes the generalized health advice of “just lose weight/diet/exercise” pretty unhelpful. Especially as we have no true recommended options that contribute to weight loss with long term maintenance.
