Dieting Might Damage Your Brain

Posted By on Tue, Aug 2, 2011 at 5:00 PM

While there might be some argument about how much of my brain I'm actually using, I definitely need whatever I have left, so I won't be dieting any time soon:

Like other parts of the body, brain cells begin to eat themselves as a last-ditch source of energy to ward off starvation, a study found.

The body responds by producing fatty acids, which turn up the hunger signal in the brain and increase our impulse to eat.

Researchers from the Albert Einstein College of Medicine at Yeshiva University in New York said the findings could lead to new scientifically proven weight loss treatments.

Tests on mice found that stopping the brain cells from eating themselves — a process known as autophagy — prevented levels of hunger from rising in response to starvation.

The chemical change in their brains caused the mice to become lighter and slimmer after a period of fasting, the researchers reported in the journal Cell Metabolism.
