Rats eat a cafeteria-style diet to excess but eat smaller amounts and less frequently when tested with chow.

Both groups showed a positive relationship between these variables in each test session: this relationship approached significance in the first test session, r = .52 for Caf-PAL rats and r = .56 for Chow-CHOW rats, larger t (10) = 2.12, p = .06, and was highly significant in the final test session, r = .74 for Caf-PAL rats and r = .71 for Chow-CHOW rats, smaller t (10) = 3.21, p<.01.
