Interventional
Description of intervention(s) / exposure
Participants in the coffee group will be required to consume 2-3 coffees per day. Coffee pods and a coffee machine will be supplied for the duration of the trial of 6 months.
1 coffee serve is equal to 1 coffee pod prepared to the participant's preference using supplied coffee machine. Coffees can be consumed at any time during the day.
Participants may consume 2 or 3 coffees per day at their own discretion.
Participants will be required to monitor intake by recording their intake in a coffee diary.

Standard lifestyle modification advice for NAFLD will be given at baseline. Advice based on European Association for the Study of the Liver (EASL) guidelines for NAFLD management.
