Ever wonder why it's so hard to keep that weight off as we age?

The NIH Directors blog explains how this research may one day lead to the development of DNA-PK inhibitors that could help us stay fit and lean as we age.  This magic pill will need to be tested for safety and effectiveness in humans, so it won't happen anytime real soon.  Fortunately in mice studies the treatment also protected the animals from developing early signs of diabetes, which is associated with obesity.  These promising results are worth keeping an eye on!
