Effect of cafeteria (CAF) diet on energy consumption and body composition in rats. (A) Weekly energy intake (kJ/rat/24 h; two-way repeated measures ANOVA, F (1, 4) = 281.7, group (p < 0.001), time (p < 0.001) and interaction (p = 0.059), (B) average daily energy consumption in chow control and CAF rats shown as (kJ/rat/24 h; average of 27 measures) (unpaired t-test; p < 0.001), (C) breakdown of energy consumed from each macronutrient (kJ/rat/24 h; average of 27 measures; carbohydrate, protein and fat; all p < 0.001, Mann–Whitney test), (D) weekly body weights analyzed by two-way repeated measures ANOVA (group × time) showing main effect of group (F (1, 26) = 45.96, p < 0.001), time (F (15, 390) = 770.87, p < 0.001) and time × group interaction (F (15, 390) = 51.38, p < 0.001), (E) fat mass (grams) and (F) absolute lean mass (grams) in chow and CAF rats measured at 13 weeks of diet. The open circle or bar indicates chow group while the filled circle or bar indicates CAF group (*** p < 0.001 versus chow). n = 14/group in panels (A–D) and n = 15/group in panels (E,F).
