Intermittent Fasting and Metabolic Dysfunction Associated Fatty Liver Disease

Not Applicable

Completed

• Conditions: Intermittent Fasting; Metabolic Dysfunction-Associated Fatty Liver Disease

• Registration Number: NCT06664684
• Lead Sponsor: Istanbul Bilgi University

Brief Summary

Previous studies have investigated the effect of different dietary patterns on metabolic dysfunction-associated fatty liver disease (MAFLD), for which lifestyle modification remains the primary treatment. The present study sought to determine the effect of intermittent fasting on anthropometric measurements, fibroblast growth factor (FGF)-21, and autophagy markers including autophagy-related protein (ATG)-5 and BECLIN-1 levels, as well as on hepatic steatosis and fibrosis levels in overweight or obese patients with MAFLD to elucidate the efficacy of intermittent fasting in the management of MAFLD. The study included 48 patients diagnosed with MAFLD. Patients were randomly assigned into two groups: 22 received a dietary treatment involving 22-25 kcal/kg/day of energy for 8 weeks (energy-restricted diet group), and 26 followed the same dietary intervention and a 16:8 pattern (energy + time-restricted diet group). The patients were assessed for various parameters at baseline (T0) and at the end of the week 8 (T8). The extent of hepatic steatosis and fibrosis was determined using transient elastography on a FibroScan® device. Serum levels of FGF-21, BECLIN-1, and ATG-5 were determined using enzyme-linked immunosorbent assay.

Primary Outcome Measures

Name	Time	Method
Transient elastography	Measurements were taken twice before and 8 weeks after the intervention.	The extent of hepatic steatosis and fibrosis was determined using transient elastography on a FibroScan® device. All FibroScan measurements were performed following the manufacturer's instructions as specified previously.

Secondary Outcome Measures

Name	Time	Method
Serum FGF-21	Measurements were taken twice before and 8 weeks after the intervention.	Serum FGF-21 were analyzed using enzyme-linked immunosorbent assay (ELISA) kits, following the manufacturer's protocols (Human FGF-21 ELISA, Biovendor, Czech Republic) and in duplicate.
Serum ATG-5	Measurements were taken twice before and 8 weeks after the intervention.	Serum ATG-5 were analyzed using enzyme-linked immunosorbent assay (ELISA) kits, following the manufacturer's protocols (Human Autophagy protein 5 \[ATG5\] ELISA Kit, MyBioSource, Inc. USA) and in duplicate.
Serum BECLIN-1	Measurements were taken twice before and 8 weeks after the intervention.	Serum BECLIN-1 were analyzed using enzyme-linked immunosorbent assay (ELISA) kits, following the manufacturer's protocols (Human BECN1 \[Beclin 1\] ELISA Kit, ElabScience, USA) and in duplicate.
