A new study finds substantial weight loss improves brain health. In the study, obese patients who underwent bariatric weight loss surgery and lost an average of 50-pounds showed improvement in multiple cognitive abilities. They included memory and executive functioning, which includes organization skills.
Researchers say it's a logical conclusion that as a body becomes healthier so does the brain. However, they said people need to not only lose weight, but also to adopt a healthy lifestyle that includes food choices and activity.
