Stress effects on food/body weight/diurnal CBT. Food consumption, body weight and diurnal amplitude data 4 days after stress exposure. (A) Stress exposure reduced food consumption, but there were no differences in food consumption between the control and test diets. The food consumption depicted was a weekly average based on food consumed from PND 85–91. (B) Similarly, stress exposure resulted in lower body weights but there were no differences in body weight between the control and test diets. (C) Stress flattened the diurnal amplitude of LA of both control and test diet groups, but diet did not alter this effect. (D) Stress also flattened the diurnal amplitude of CBT of both control and test diet groups, however, the test diet group had an attenuated disruption in the diurnal amplitude of CBT when compared with those on the control diet. Abbreviations are as follows: a.u., arbitrary units; CBT, core body temperature; g, grams; LA, locomotor activity; PND, post natal day (*p < 0.05 vs. no stress; ^#p < 0.05 vs. control diet).
