A study conducted on a group of participants showed that overweight and obese individuals, people with a body mass index (BMI) greater than 25, had several abnormal brain biochemical deficiencies in both the white and gray matter.
According to Dr. Dieter Meyerhoff, professor of radiology at the University of California, “[The] results suggest that the brains of people who are overweight or obese age faster than the brains of people of normal weight, and thus these individuals are at increased risk of developing dementia.”
However, this can be prevented with proper diet and exercise. According to Ilchi Lee, originator of the Brain Education System Training (BEST) and author of In Full Bloom: A Brain Education Guide for Successful Aging, “Brisk cardiovascular exercise brings rich, oxygenated blood to the brain. You should get at least 30 minutes of heart-pumping exercise three times a week.” And don’t forget strength training, which also produces more energy for the brain.
With an estimated 150 million Americans now classified as overweight or obese, it’s more important than ever to keep your weight normal and your heart pumping. Not only will it keep your body in shape, it will also keep your brain in shape—and young.
