increase very often, because it will wreck my knee joints and spine.

Came to the same result as Bill on the added calories needed to bring
the pack up one flight of stairs. But that's just the extra energy now
"stored" in the package as potential energy.
A backwards trace of the energy could look something like this:
To transfer the energy to the package, your muscles has to do work.
Muscles are machines that convert some of its fuel to work, and some
to heat. So the energy for both must come from food, which is where we
usually count calories.
So the number of calories you need to ingest to perform the work is
far greater than Newtonian physics will have you believe from the
perspective of the package. :-)

What is the difference in virtual weight of a pack (say, ten lbs)

It's 42.
Actually, it's about 32.4 calories to carry 10 pounds up a flight of
stairs
presuming 10' from floor to floor.
