Body composition of lean mass and fat mass determined by dual-energy X-ray absorptiometry in male (A and C) and female (B and D) mice fed CAS, AA, or GMP diets. Final composition of lean and fat mass was assessed (A and B). ^a,b,cMeans with different superscripted letters are significantly different (P < 0.05). The percentage of body fat was assessed over time (C and D). ^a,b,cMeans with different superscripted letters indicate significant differences in mean %body fat at the midpoint of time (P < 0.05). Male mice showed significant genotype × diet interaction, as reflected in presentation of the six groups (A and C). Female mice showed a significant main effect for dietary treatment without significant interaction with genotype, as reflected in combining the female WT and PKU dietary groups (B and D). Nos. in parentheses indicate sample size.
