Diet and Meal Timing in Patients With Non-Alcoholic Fatty Liver Disease: A Pilot Study
- Conditions
- Non-Alcoholic Fatty Liver Disease
- Interventions
- Behavioral: SOCBehavioral: TRE plus SOCBehavioral: TRE
- Registration Number
- NCT05332613
- Lead Sponsor
- Weill Medical College of Cornell University
- Brief Summary
This study will assess the impact of time-restricted eating (8 hours of eating each day) with standard of care lifestyle recommendations (hypocaloric, Mediterranean diet and 30 minutes of exercise on at least 5 days/week) on the degree of fat in the liver as measured by magnetic resonance imaging.
- Detailed Description
Time-Restricted Eating (TRE) is a form of caloric restriction through daily prolonged fasting that has been shown to lead to weight loss, improved glucose regulation, and suppression of inflammation. Non-alcoholic fatty liver disease (NAFLD) is a metabolic condition that in certain patients can lead to significant morbidity and mortality. The only current treatment for NAFLD is weight loss. In the proposed study, the investigators aim to test the hypothesis that TRE will add additional benefit in the treatment of NAFLD on top of standard of care diet and lifestyle modifications.

Group Intervention Description SOC SOC lifestyle modifications and weight management. Participants will be given lifestyle recommendations with respect to diet and exercise. The registered dietitian (RD) will obtain a baseline dietary record and provide counseling on the time-restricted eating regimen. A baseline dietary record will be assessed prior to fasting initiation with the RD in person. The RD will also collect the subject's normal diet and exercise routine. The RD will instruct the participants regarding standard of care lifestyle recommendations. This includes education of a low-calorie diet (500-1000 kcal) and moderate-intensity exercise. TRE plus SOC TRE plus SOC Participants will be required to fast each day for 12 weeks and will be given lifestyle recommendations with respect to diet and exercise. The registered dietitian (RD) will obtain a baseline dietary record and provide counseling on the time-restricted eating regimen. The RD will collect the participant's normal diet and exercise routine. Counseling will involve instructing the participant to choose an eight-hour eating window (e.g., 10:00am - 6:00pm) during which the participant will be able to eat. During the 16-house fasting window (e.g., 6:00pm - 10:00 am), the participant is able to drink regular water and black coffee or tea. The RD will be available to answer any questions the participants may have pertaining to the regimen and will instruct the participants regarding standard of care lifestyle recommendations. This includes education of a low-calorie diet (500-1000 kcal) and moderate-intensity exercise. Crossover to TRE TRE Participants who have not lost weight or have lost less than or equal to 5% of their body weight, they will be given the option to crossover to the TRE arm. Following the initial 12-week period and end of study MRI, participants would restart another identical 12-week cycle but adhering to the exact steps of the TRE arm including another 4 visits with the registered dieticians (RDs) and an end of study visit with repeat Fibroscan, InBody 770 body composition scan, and MRI-PDFF.
- Primary Outcome Measures
Name Time Method Percentage of Patients Who Achieve At Least 30% Reduction in Liver Fat at 12 Weeks 12 weeks Evaluate the percentage of patients with baseline NAFLD (MRI-PDFF greater than or equal to 10%) who achieve clinically significant improvement in hepatic fat, as defined by greater than or equal to 30% reduction from baseline liver fat on MRI-PDFF, while adopting a time-restricted eating pattern (fasting 16 hours per day) along with standard of care management as compared to patients with only standard of care NAFLD management.
- Secondary Outcome Measures
Name Time Method Mean Change from Baseline in Quality of Life Score on SF-36 at 12 weeks Baseline, 12 weeks Evaluate the mean change of quality of life score from SF-36 from baseline to 12 weeks. Scores range from 0-100. Higher scores indicate better health status, while lower scores indicate a poorer health status. A mean score of 50 has been articulated as the normative value of all scales.
Mean Change from Baseline in BMI at 12 weeks Baseline, 12 weeks Evaluate the mean change of body mass index from baseline to 12 weeks.
Mean Change from Baseline in Body Composition Measurements at 12 weeks Baseline, 12 weeks Evaluate the mean change of body composition measurements as measure by InBody Body
Mean Change from Baseline in aspartate transglutaminase at 12 weeks Baseline, 12 weeks Evaluate the mean change in aspartate transglutaminase from baseline to 12 weeks.
Mean Change from Baseline in alanine transglutaminase at 12 weeks Baseline, 12 weeks Evaluate the mean change in alanine transglutaminase from baseline to 12 weeks.
Mean Change from Baseline in Weight at 12 weeks Baseline, 12 weeks Mean Change from Baseline in Liver Stiffness on Fibroscan® at 12 weeks Baseline, 12 weeks Evaluate the mean change in liver stiffness as measured by (FibroScan®) from baseline to 12 weeks.
Mean Change from Baseline in total bilirubin at 12 weeks Baseline, 12 weeks Evaluate the mean change in total bilirubin from baseline to 12 weeks.
Mean Change from Baseline in direct bilirubin at 12 weeks Baseline, 12 weeks Evaluate the mean change direct bilirubin from baseline to 12 weeks.
