Nonalcoholic fatty liver disease (NAFLD) is a widespread condition in the Western World. Around 30% of the population have lipid droplets stored in their liver which diminish its function in the long term. Main causes for NAFLD are our high-caloric diet in combination with a sedentary lifestyle. Hitherto, researchers have not fully understood the cause of this disease and despite the high number of affected individuals, there is no approved therapy.
