Abstract

Background & aims Around 10-20% of patients with non-alcoholic fatty liver disease (NAFLD) are non-obese. The benefit of weight reduction in such patients is unclear. We aim to study the efficacy of lifestyle intervention in non-obese patients with NAFLD and to identify factors that predict treatment response.Methods A total of 154 community NAFLD patients were randomised to a 12-month lifestyle intervention programme involving regular exercise, or to standard care. The primary outcome was remission of NAFLD at Month 12 by proton-magnetic resonance spectroscopy. After the programme, the patients were prospectively followed until Year 6. The Asian body mass index (BMI) cut-off of 25 kg/m 2 was used to define non-obese NAFLD.Results Patients were assigned to the intervention (n = 77) and control (n = 77) groups (39 and 38 in each group had baseline BMI <25 and ≥25 kg/m 2, respectively). More patients in the intervention group achieved the primary outcome than the control group regardless of baseline BMI (non-obese: 67% vs. 18%, p <0.001; obese: 61% vs. 21%, p <0.001). Lifestyle intervention, lower baseline intrahepatic triglyceride, and reduction in body weight and waist circumference were independent factors associated with remission of NAFLD in non-obese patients. Half of non-obese patients achieved remission of NAFLD with 3-5% weight reduction; the same could only be achieved in obese patients with 7-10% weight reduction. By Year 6, non-obese patients in the intervention group remained more likely to maintain weight reduction and alanine aminotransferase normalisation than the control group.Conclusions Lifestyle intervention is effective in treating NAFLD in both non-obese and obese patients. Weight reduction predicts remission of NAFLD in non-obese patients, but a modest weight reduction may be sufficient in this population.Lay summary Some patients with non-alcoholic fatty liver disease (NAFLD) are non-obese. The optimal management of such patients is unclear. In this long-term follow-up study of a clinical trial, we show that remission of NAFLD can be achieved in 67% of non-obese patients after lifestyle intervention. The majority of patients can achieve NAFLD remission with modest weight loss of 3-10%. Non-obese patients are also more likely than obese patients to maintain weight reduction and normal liver enzymes in the long run.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
