Randomized controlled studies investigating the impact of replacing dietary carbohydrates with polyunsaturated fat (PUFA) on liver fat content and cardiometabolic risk in individuals with prediabetes and T2D are lacking. Also, the effects of a Healthy Nordic Diet on liver fat content and glycemic control have not be investigated. This study therefore aims to: Investigate the effects of the diets on liver fat content (primary aim) Investigate the effects of the diets on pancreatic fat, visceral fat, lean tissue, glycemic and lipid control Investigate the effects of the diets on plasma markers of de novo lipogenesis (DNL) and desaturation (i.e. stearoyl-Coenzyme desaturase 1, SCD-1) as well as on hepatic DNL using MRI spectroscopy Investigate gene-diet interactions, especially if common gene variants (e.g. in PNPLA3) known to increase liver fat and dyslipidemia, may modify the dietary effects. Perform lipidomic analyses to identify potential mechanistic pathways that may associate with diet-induced changes in liver fat, pancreatic fat, visceral fat, insulin sensitivity, dyslipidemia or DNL Our hypothesis is that a customized diet will effectively reduce liver fat through suppression of hepatic DNL and SCD-1 activity, and thereby improve atherogenic dyslipidemia, insulin resistance and hyperglycemia in individuals with prediabetes and T2D.
