Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The investigators will conduct an open label, experimental medicine study exploring the diurnal patterns of hepatic lipid metabolism in NAFLD and non-NAFLD participants (determined by Transient elastography (TE) with controlled attenuation parameter (CAP)). We will also determine whether the diurnal patterns of lipid metabolism in NAFLD participants can be modified using lifestyle and weight loss intervention. Fourteen participants without NAFLD will have morning and evening metabolic investigations (visit 1M \& 1E) to assess for changes in lipid flux pathways across the course of the day. After morning and evening investigations their involvement in the clinical study will then end. Seventeen NAFLD participants will also have identical baseline morning and evening investigation after which they will be enrolled into a 12-week lifestyle and weight loss programme. After 12-weeks, all 17 participants with NAFLD will have a follow up CAP, and morning and evening metabolic investigations (visit 2M \& 2E).
