For the first time scientists have kick-started the natural process by which genetically predisposed obese mice gain weight, opening up a new potential approach to fight off obesity. The study that was presented today at The International Liver CongressTM in Barcelona, Spain suggests that impaired brown adipose tissue (BAT), otherwise known as 'brown fat', drives obesity, and … [Read more...]

A new study presented today demonstrates that a build-up of fat around the waist can cause more serious complications than obesity in the development of non-alcoholic fatty liver disease (NAFLD).
