Note. BER = binge eating resistant; BEP = binge eating prone; Stage = pre-early puberty, mid-late puberty, or adulthood. Pre-early puberty and mid-late puberty varied by rat, but occurred between feeding tests 1–7 and 6–16, respectively, for the full sample. Adulthood occurred between feeding tests 17 and 21 for all rats.
