A large genetic study identified five major genetic groups underlying 14 psychiatric disorders, revealing shared genetic factors across conditions and highlighting the complex interplay between genetics and environmental factors in mental health. The findings suggest that mental illnesses are influenced by natural genetic variation and environmental stress rather than being solely biological defects.
Modern science reveals that weight loss is hindered by our brain's biological defenses, which evolved to protect our ancestors from starvation, making it difficult for many to lose weight and keep it off. These defenses include increased hunger and reduced energy expenditure after weight loss, and the brain's memory of previous higher weights. While medications and societal measures can help, understanding that obesity is a biological condition rather than a personal failure is crucial for effective treatment and prevention.
