Obesity and its complications such as fatty liver, type 2 diabetes and cardiovascular disorders are complex metabolic diseases that are polygenic and develop due to increased food intake and reduced physical activity. The genes identified so far can only explain a small part of the hereditary component of these diseases. Therefore, our group aims to gain further insights into the genetic factors and to investigate whether different interventions, such as intermittent fasting and exercise, can alter the expression of these genes.
