LC, lean control; LF, lean fibre; LHF, lean high fibre; OC, obese control; OF, obese fibre; OHF, obese high fibre.
Mean values were significantly different from control diet within lean and obese groups.
Caecal weight refers to the caecal tissue and the wet contents. Caecal TAG and cholesterol are expressed as mg/g total caecal weight (tissue + contents).
Mean values were significantly different between the 10 and 20 % fibre diets within lean and obese groups as determined by a two-way ANOVA with a Holm–Sidak adjustment for multiple comparisons (P≤0·05).
