I get this over and over on every issue where "math" becomes "guidance". Let me try to bridge by restating:

Math truth is not always good policy guidance.

It is true that CI==CO. It must. It is not true that telling someone that CI==CO is a good way to get them to manage their weight, because (as mentioned) it's hard to measure and (as I added) even if you measure correctly, you _reduce likelihood of compliance_ by ignoring appetite effects when you call all calories equal.

I think we agree, just trying to find the right words anyway.

Exactly, yes we agree. It's why I think the debate is inane from both angles. CICO is both true and yet not useful.
