[Summarizing was shorter than quoting.]

Since he spoke of "one or more words," I'll assume that spaces and tabs do
not make a body non-empty, nor that punctuation marks do.  So let's check
for digits and letters of the alphabet (remember that procmailrc regexps are
case-insensitive if you don't use the `D' flag):

  :0B
  * ! [a-z0-9]
  { routine for an empty body }

If you have other conditions that preclude using a `B' flag on the flag line,
set it as the search area for that one condition:

 * ! B ?? [a-z0-9]
