It's the second most preventable cause of death in the United States... obesity, or even just being overweight.  While it's easy for many people to lose weight, a new study shows that having someone to help maintain the loss can keep the weight off.   
    Researchers compared two different weight maintenance methods with self-directed maintenance.  One group had regular meetings with a counselor, while the other group used self-directed interactive technology.  While most people maintained their loss, the greatest losses were in the group who met with a counselor.
