The Physics of a "Proclaimer" Walking 500 Miles, and then Attempting to Walk 500 More

I suppose this was inevitable, but there is now a paper on the physics of a "Proclaimer" walking 500 miles and then attempting to walk 500 more.

Quoting from the abstract: In this paper we examine the feasibility for a Proclaimer, modelled on the average Scottish male human, to walk such distances without food. It was found that a Proclaimer, would lose 1.3% of its body mass after 500 miles and 2.8% after 500 more.

That seems like a rather significant underestimate of how much body mass the Proclaimer would lose.
