Study Overview: This study focuses on a liver condition called non-alcoholic fatty liver disease (NAFLD), which can lead to serious health problems like liver cancer. The study aims to test a new way to measure liver fat using a tool called the continuous controlled attenuation parameter (CAPc), which might be easier and cheaper than the usual method called MRI-PDFF (magnetic resonance imaging proton density fat fraction).

Participants will join a 6-month program to change their diet and exercise habits, which helps reduce liver fat. The study will compare how well CAPc measures liver fat changes against MRI-PDFF.

• **Duration and Visits:** The study lasts 6 months with 4 clinic visits.
• **Tests and Procedures:** Includes blood tests, liver scans, and lifestyle assessments.
• **Eligibility:** Participants must have a certain level of liver fat and meet specific health criteria.
