Data for all groups were compared using ANOVA, with the Student-Neuman-Keuls post hoc test. For body mass on day 21, initial body mass (body mass on day 0) was used as a covariate. Values are means ± s.e.m.. *, ** and ***, significantly different (P < 0.05, 0.005 and 0.001, respectively) versus WL5, WL10, WL29 and WL53. Wheel lock groups not sharing a letter for relative food intake on the last night are significantly different (P < 0.05). n = 26 each for WL5, WL29, WL53, and SED5. n = 10 each for WL10 and SED10.
