Genetics and Epigenetics of Obesity
The genetics and epigenetics of obesity reveal how inherited traits and environmental factors interact to influence body weight and fat distribution. Genetic predispositions can affect appetite regulation, metabolism, and fat storage, making some individuals more susceptible to obesity. Recent research into epigenetics shows how lifestyle and environmental exposures can alter gene expression without changing the DNA sequence itself, potentially increasing the risk of obesity. These epigenetic changes can impact how genes related to hunger, metabolism, and fat storage are expressed.
