Healthy Nordic Diet Improves Liver Fat in Type 2 Diabetes

Last updated July 18, 2026

Key finding

Liver fat was reduced by -1.46% (95% CI: -2.42, -0.51).

This study examined the impact of a low-carbohydrate high polyunsaturated fat diet on liver fat in individuals with type 2 diabetes, finding significant reductions in liver fat and body weight with the Healthy Nordic Diet.

Plain-language summary

What this paper says

A plain-language read of the study’s main message and where it applies.

Study focus

Clinical relevance

These findings highlight the potential of dietary interventions, particularly the Healthy Nordic Diet, in managing liver fat and improving metabolic health in individuals with type 2 diabetes. This could inform dietary recommendations and lifestyle changes for better diabetes management.

Keep in mind

The study may have limited generalizability due to specific population characteristics. Sample size and duration of the study might affect the robustness of findings. Potential confounding factors were not fully controlled.

Main Effects

Liver fat reduced by -1.46% (95% CI: -2.42, -0.51) in the LCPUFA diet group.

Liver fat reduced by -1.76% (95% CI: -2.96, -0.57) in the HND group.

Body weight decreased significantly more in the HND group compared to the other diets.
