Figure 1. Cumulative food intake (A) and caloric intake (B) of Y₁R/LacZ transgenic male or female mice fed either standard chow (black bars) or MHF diet (grey bars) for 8 weeks.

Data are the sum of mean grams per mouse (A) and mean kilocalories per mouse (B) that were determined on the 7th day of each week and are means ±s.e.m. from three experiments (N = 5–6). One-way ANOVA; A, F_3,8 = 6.062, P = 0.019. *P < 0.05 versus chow-fed females and MHF diet-fed males, by Newman–Keuls test; B, F_3,8 = 6.043 P = 0.019. *P < 0.05 versus chow-fed males and MHF diet-fed females, by Newman–Keuls test.
