Nutrition and Physical Activity in Nonalcoholic Fatty Liver Disease

Abstract EN

Nonalcoholic fatty liver disease (NAFLD) is the most common liver disease worldwide and it is associated with other medical conditions such as diabetes mellitus, metabolic syndrome, and obesity.

The mechanisms of the underlying disease development and progression are not completely established and there is no consensus concerning the pharmacological treatment.

In the gold standard treatment for NAFLD weight loss, dietary therapy, and physical activity are included.

However, little scientific evidence is available on diet and/or physical activity and NAFLD specifically.

Many dietary approaches such as Mediterranean and DASH diet are used for treatment of other cardiometabolic risk factors such as insulin resistance and type-2 diabetes mellitus (T2DM), but on the basis of its components their role in NAFLD has been discussed.

In this review, the implications of current dietary and exercise approaches, including Brazilian and other guidelines, are discussed, with a focus on determining the optimal nonpharmacological treatment to prescribe for NAFLD.
