May 6, 201016 yr High stress levels can make you fat, researchers claim By Daily Mail Reporter Last updated at 2:50 PM on 6th May 2010 Comments (4) Add to My Stories Most people trying to lose weight know it's a case of eating less and moving more. But weight-watchers may also do well to cut down on the stress in their lives if they want to drop a few pounds. New research has found that that high levels of anxiety can cause people to become obese. Weight problem: Stress activates a gene which affects the metabolism and contributes to our cravings for sweet, fatty foods, according to a new study The Israeli study found that stress activates a gene which affects the metabolism and contributes to our cravings for sweet, fatty foods. Dr Alon Chen, a neuro-endocrinologist at the Weizmann Institute, said: 'We showed that the actions of a single gene in just one part of the brain can have profound effects on the metabolism of the whole body.'

It starts with the pressure to fit in at school at five, pass exams, get into a good university, pay off student loans, meet mortgage payments - and before you know it, you're worrying about university fees for the children. 'Stress is definitely influencing every system in the body,' said Dr Chen. 'It's not just causing anxiety, depression and post-traumatic stress disorder but is influencing metabolic syndromes such as obesity.' In the study, published in the Proceedings of the National Academy of Sciences, the researchers discovered a 'stress switch' that can lead to both obesity and diabetes. The scientists created their own method for changing the activity of the gene on the brain, causing it to release varied amounts of a protein called Ucn3. They discovered that increased levels of Ucn3 caused anxiety and changes in metabolism. With increased levels of Ucn3, the bodies of mice used more sugar and less fatty acids and metabolic rates increased, showing the first stages of type 2 diabetes. Dr Chen added: 'Until now, the lines drawn between stress, appetite and anxiety were pointed out, but never fully explained. '�This new research may be the important missing link that can help drug developers create drugs targeting stress that could have multiple side-benefits, like preventing diabetes, promoting heart health and keeping our weight down.'

May 8, 201016 yr ^ I'm not fat either, but that obviously makes sense... I think it's because we're too young to have any noticeable effect of stress on our metabolism (which might be very high)... but then we must wait until we're 30-40. :confused:
