Being Overweight or Obese Could Damage Your Brain, Finds a Study

(26 November is observed as Anti-Obesity Day annually to raise awareness about the health hazards associated with obesity. FIT is reposting this story in that light.)

Results of a study has shown a possible link between body weight and brain health. Obesity could be connected to cortical thinning and brain atrophy.

Cortical thinning refers to the cerebral cortex, the part of the brain where all the information is processed. The thinner the cortex, the greater the risk of neurological and Alzheimer’s diseases.

Around 1200 people were recruited for the study to compare their bodies and brains. Their BMI and waists were recorded at the initial stage of the study and six years later, their brains were scanned by MRI to measure the thickness of the cortex and the brain volume.

Every unit increased in BMI made the cortex thinner by 0.098 mm in people who were overweight, and 0.207 mm thinner in those who are obese.

The results revealed that the higher the BMI, the thinner the cortex. Out of all the people observed, 371 people were obese, having BMIs 30 and above, 571 were overweight, with BMIs between 25 to 30.

Fatherly quotes study author and neurologist Dr Tatjana Rundek,

The overall thinning rate of the cortical mantle is between 0.01 and 0.10 mm per decade, but being overweight or obese speeds up this process by at least another ten years. Having a broader waist is also associated with thinner cortex.

While the scientists failed to give some strong evidence for the fact that there is a direct correlation between putting on weight and neurological diseases, the results are indicate a serious issue.

The study is alarming and the young generation should primarily focus on maintaining a healthy lifestyle and habits.
