Updated: 1/31/19 A recent study has found that the brains of individuals who are overweight, appear '10 years older' when compared to individuals of normal weight.
Why is this? As people age, the brain naturally loses its white matter (the part of the brain that sends information.)
Recently, a Cambridge University group discovered that the loss of the brain's white matter was intensified with individuals who carry extra weight, indicating that extra weight negatively affects brain function.
The team who completed the study, from the Cambridge Center for Aging and Neuroscience, looked at the brains of 473 people between the ages of 20 and 87, dividing them into lean and overweight groups.
Their findings, published in the journal Neurobiology of Aging, found significant differences in the volume of white matter in the brains of overweight people compared with leaner people. Those in the overweight group had much less white matter than individuals in the leaner group.
Professor Sadal Farooqi, from the Welcome Trust Medical Research Council Institute of Metabolic Science at Cambridge University, who also worked on the study, stated "It will also be important to find out whether these changes could be reversible with weight loss, which may well be the case. This must be a starting point for us to explore in more depth the effects of weight, diet and exercise on the brain and memory."
