As if we don't have enough known implications of being overweight. A new study shows that besides an increased risk of heart-related diseases and other scary ailments, obese people are also prone to "severe brain degeneration".

Obese people have 8 percent less brain tissue than normal-weight individuals and look an alarming 16 years older (the brain)!

"That's a big loss of tissue and it depletes your cognitive reserves, putting you at much greater risk of Alzheimer's and other diseases that attack the brain," said Paul Thompson, senior author of the study and a UCLA professor of neurology.

Eating healthily is the first step - and most important - in reducing this risk. The brain's critical areas for memory, planning, attention, movements are all at risk of depleting quickly in obese people.
