1 Mean ± SEM
2 Main effect of diet p = 0.025 using repeated measures ANOVA. Variables with different superscripts are significantly different using Tukey's test for post hoc analysis (P < 0.05).
3 No significant effect of time or diet using repeated measures ANOVA
4 Main effect of diet P < 0.001. Variables with different superscripts are significantly different using Tukey's test for post hoc analysis (P < 0.05).
5 Main effect of time using repeated measures ANOVA P < 0.0001
VLCARB = very low carbohydrate diet (n = 24) VLF = very low fat diet (n = 22) HUF = high unsaturated fat (n = 21)
