Chronic consumption of western diet results in altered feeding behavior in female mice.

Female mice maintained for ten weeks (a, cumulative change in body weight; b, gross body weight) on a western diet (Western) become obese and display increases in 24 h meal size and rate of intake paired with a decrease in meal duration (c-e) when compared to mice maintained on a standard chow diet (Stand). Meal frequency, total caloric intake, dark cycle intake, light cycle intake, and post meal interval do not significantly differ between diets (f-j). Repeated measures two-way ANOVA, with Sidak's multiple comparison post hoc test, *** = p<0.001, ** = p<0.01, * = p<0.05 (a,b); unpaired Student's t-test (two-tailed), *** = p<0.001, * = p<0.05 between Stand and Western. Results are expressed as means ± SEM; n = 6 per condition.
