Effects on body weight, fat mass and energy intake of Control-, NASH-, HFD- and HFr-diets. a Body weight increased in all 4 diet groups throughout the study, but did not differ after 16 weeks. b After 8 weeks fat mass was significantly increased in HFD-fed rats compared to Control- and HFr-fed rats. This effect was still present at week 16. c After 8 weeks, accumulated energy intake was significantly higher in NASH-fed rats, compared to both Control- and HFr-fed rats and in HFD-fed rats compared to Control. This remained significant only in NASH-fed compared to Control-fed rats after 16 weeks. Comparisons between groups: *NASH vs. Control; #NASH vs. HFr; †HFD vs. Control. Statistical significance: *p < 0.05; ***p < 0.001; #p < 0.05; ##p < 0.01; †p < 0.05
