Reuben Kaufman and graduate student Brian Weiss have found that for females, the secret to staying slim is staying virginal. Fortunately for males, human and otherwise, this works only if you're a special type of tick. Kaufman and Weiss have isolated the engorgement factor protein (EF) in the semen of the tick family ixodidae; this protein inspires gluttony in inseminated females. They have dubbed it "voraxin," from the Latin vorare, to devour.
