Exercise, obesity, brain health

From the New York Times
How Fat May Hurt the Brain, and How Exercise May Help 
By GRETCHEN REYNOLDS 
Obesity may have harmful effects on the brain, and exercise may counteract many of those negative effects, according to sophisticated new neurological experiments with mice, even when the animals do not lose much weight. While it’s impossible to know if human brains respond in precisely the same way to fat and physical activity, the findings offer one more reason to get out and exercise.
It’s been known for some time that obesity can alter cognition in animals. Past experiments with lab rodents, for instance, have shown that obese animals display poor memory and learning skills compared to their normal-weight peers. They don’t recognize familiar objects or recall the location of the exit in mazes that they’ve negotiated multiple times.
 One more article to reinforce what we already know. It's important to make time for exercise if we want to have a healthy mind and body.
