The journal, Obesity Reviews, has published a article that adds to the evidence that obesity is unhealthy to the brain. The greater a subject’s Body Mass Index (BMI), the greater the disruptions were found in the white matter of the brain. These changes were even greater with increasing age of the subjects. The limbic system, which is responsible for emotional control, is disproportionately affected.
The bottom line is that it is very worthwhile to maintain a healthy BMI via sensible nutrition, exercise, and good sleep habits. Support those you care about in finding good brain and body health.
