it appears that I should have been more clear. Yes. Work does have several definitions, one is, "all energy exerted including energy to persist - i.e. sleep, Base Metabolic rate, incidental exercise and actual purposeful exercise", and the other is, "the actual activity alone, excluding the base metabolic rate".

I intended to use this definition for the whole post: "all energy exerted including energy to persist - i.e. sleep, Base Metabolic rate, and actual activity"

If you only count the work that people purposely do - 90% or more of the picture will be left out. Similar if I only counted the food I ate while "dieting" (or "having a meal") and not the food I eat while "snacking" or "being hungry" or other definitions of what doesn't count.
