Exercise may protect brain volume by keeping insulin and BMI
Studies have shown that exercise helps protect brain cells. The study involved 134 people with an average age of 69 who had no memory problems. The people filled out surveys about their physical activity over the past year. They had brain scans to measure volume and glucose metabolism. Information was gathered on BMI and insulin levels as well as cholesterol, blood pressure and other factors.

People with the most physical activity had a higher total volume of grey matter in their brains than people with the least amount of physical activity, with an average of about 550,000 cubic millimeters (mm³) compared to about 540,000 mm³. When researchers looked only at areas of the brain affected by Alzheimer's disease, they found the same results.

Those with the most activity also had a higher average rate of glucose metabolism in the brain than those with the least amount of activity. Maintaining a lower BMI through physical activity could help prevent disturbed insulin metabolism that is often seen in aging, thus promoting brain health.
