There's a new reason to lose weight. For every excess pound piled on the body, the brain gets a little smaller. That's according to new study that found that elderly individuals who were obese or overweight had significantly less brain tissue than individuals of normal weight.

Researchers from UCLA say much of that tissue was in the frontal and temporal lobe regions of the brain. That's the decision-making and memory portion of the brain.

The findings could have serious implications for aging, overweight or obese individuals, including a heightened risk of Alzheimer's.
