Body weight, body fat, and daily food intake of mice used in the meal pattern experiment. During the 22 d of meal pattern testing, when mice were 3–4 months of age, no differences in body weight emerged between WT (n = 13; 7 males, 6 females), INT-BDNF+/− (n = 14; 7 males, 7 females), and INT-BDNF−/− (n = 15; 7 males, 8 females) mice (A). In addition, there were no differences in body fat, here calculated as percentage of body weight, between any of the three genotypes or between males and females (B). Average total daily food intake during the meal pattern collection remained normal in INT-BDNF+/− and INT-BDNF−/− mice in both males and females (C).
