As if you needed another reason to get and stay in shape, a new study has concluded that obese and overweight people have "significantly less" brain tissue than persons who are of normal weight.

According to the study's senior author, UCLA neuroscientist Paul Thompson, "the brains of obese people looked 16 years older than their healthy counterparts while [those of]overweight people looked 8 years older." He added that "this is the first study to show physical evidence in the brain that connects overweight and obesity and cognitive decline."
The study examined brain images of 94 people in their 70s over five years and concluded that subjects classified as clinically obese had eight percent less brain tissue, while overweight persons studied had four percent less brain tissue when compared to "normal" weight people.
