I guess here we are making a distinction, on a 'feed' day, between having your normal TDEE every day, or having the occasional 'feast' day (over TDEE) which should be balanced by a 'frugal' day (under TDEE).
I think a feast/frugal strategy would be dangerous for most of us, and it overcomplicates things, but we are all going to feast occasionally (like me yesterday) so we say it isn't a disaster because (a) you can match it with a frugal day and (b) maybe (Caroline's experience) the combination could actually be a bit better for weight loss than 2 normal feed days.
