There is no report in literature on possible physiological changes that accompany dietary modification in obese condition. Moreover, there is no conclusive evidence on the optimal amount of virgin coconut oil (VCO) that could be of health benefit, although it is known to enhance lipid metabolism. Therefore, we investigated the antiobesitogenic action of graded doses of VCO (200, 400 and 600 mg/kg) in obese rats fed with normo/hyper-lipidaemic diet. Sixty rats (n = 10) were divided into 6 groups and treated as follows: the control and high fat diet (HFD) groups were administered normal saline (0.1 mL/day, p.o.) during the last four weeks of the study, and were fed with normal and HFD respectively throughout the twenty weeks duration of the experiment. Groups 3-6 were fed with HFD for 16 weeks, then normal diet during the next 4 weeks. While group - 3 received saline (0.1 mL/day, p.o.) during the last four weeks, groups 4-6 received graded doses of VCO. The results showed that HFD-induced obesity caused impaired glucose homeostasis, distorted hepatic histoarchitecture, selected deviations in hepatic function indices, pro-inflammatory, pro-oxidant, and dsylipidaemic effects. There were evidence of escalated and reversed pathological actions following the replacement of HFD with normal diet. VCO showed no effect on glucose, insulin, insulin resistance, total protein, uric acid and TAC; but equitable effects on CAT, IL-6, CRP, ALT, AST&GGT, irrespective of the dose. Compared to the effects of VCO at 400 and 600 mg/kg, at 200 mg/kg, VCO had more significant therapeutic effects on LDH, MDA, SOD, GPX, TC, TG, LDL-C, total bilirubin, atherogenic and lee indices and hepatic histoarchitecture. Conclusively, VCO, preferably at a low dose could be used to reverse hepatic structural alteration and some biochemical deviations following dietary modifications in obese condition.
