Study: Losing Weight Improves Memory

Ad Feedback

CBNNews.com  - Once again medical science is touting the health benefits of losing weight. A leaner body equals a sharper mind and better memory.

Researchers tested the memories of overweight men and women, who were about 60 years old.

Then they slashed their calorie intake by nearly a third and were tested again in three months.

After losing weight, they scored significantly higher on the memory test.

"These are the most robust and persuasive results we've seen," said Dr. Sam Gandy of Mt. Sinai School of Medicine. "I think the results are extremely exciting. I think this provides hope for a way we can intervene in humans and improve memory."

In fact, the more people lost, the better their memory.

Cutting calories boosts your insulin sensitivity and fights inflammation, two things that cause your brain to function more efficiently.

But if you're already at a healthy weight, no need to lose more. Regular, vigorous exercise also boosts your memory.

"I think the results are extremely exciting. I think this provides hope for a way we can intervene in humans and improve memory," Gandy added.

So in addition to looking better and feeling better, diet and exercise can also make you think better.
