Scientists Create Mice Resistant to Obesity

SUNDAY, Aug. 10 (HealthDay News) -- Researchers have developed a strain of mice resistant to diet-induced obesity.

The findings could one day lead to possible drug treatments for obesity in people. They also shed light on the brain circuitry that controls energy homeostasis -- the balance between how much energy (i.e., food) an animal takes in and how quickly it burns that energy.

Dr. Julio Licinio, a professor of psychiatry and behavioral sciences at the University of Miami Miller School of Medicine, called the research a "technological tour de force."
