A fasting-mimicking diet programme reduces liver fat and liver inflammation/fibrosis measured by magnetic resonance imaging in patients with type 2 diabetes
Abstract
BACKGROUND & AIMS: This study aimed to assess whether a fasting-mimicking diet (FMD) programme as an adjunct to usual care can reduce liver fat and liver inflammation/fibrosis as measured by Magnetic Resonance Imaging (MRI) in patients with type 2 diabetes.
METHODS: This study analyses secondary outcomes of the Fasting In diabetes Treatment (FIT) trial, which was a randomised, controlled, assessor-blinded trial in which people with type 2 diabetes using metformin only and/or diet alone for glycaemic control were randomised to receive 5-consecutive day cycles of FMD monthly as adjunct to usual care or usual care only for twelve months. Laboratory measurements, anthropometric measurements and MRI were performed at baseline, 6 and 12 months. Two MRI-derived biomarkers were measured: proton density fat-fraction (PDFF), a biomarker for liver fat, and iron content corrected T1 (cT1), a biomarker for liver inflammation/fibrosis.
RESULTS: Data were available of 89 participants who completed baseline visits including MRI (n = 48 in the FMD group and n = 41 in the control group). Intention-to-treat analyses, using linear mixed models, revealed significant adjusted estimated treatment effects of the FMD on PDFF (-2.8 %, 95 % CI -4.7 to -0.8, p < 0.01) and cT1 (-29.9 ms, 95 % CI -51.8 to -8.0, p < 0.01) at 12 months. In a post-hoc analysis, more participants in the FMD group compared to the control group transitioned from high to low risk for liver disease and cardiovascular disease…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 89 participants or records.
