The aim of this randomized interventional trial is to understand the effects of peanut consumption on patients with metabolic associated fatty liver. The main goal is to investigate if patients who consume peanuts have improved liver marker tests as well as metabolic profile. We will also investigate how peanuts alter the gut microbes and liver fat content in patients with metabolic associated fatty liver.

• Stool sample and blood (for biomarkers) collection across both arms at baseline and post-intervention
• Daily log to be completed for tracking peanut consumption
• 2-day Dietary recall at baseline, during Week 6 and Week 12
• Poat intervention Fibro scans for participants with baseline scans available
