Excessive body fat linked to smaller brain

Excessive body fat linked to smaller brain

A 2018 study, for instance, has shown that people with excess belly fat have twice the risk of suffering from heart attack or die from cardiovascular problems regardless of their weight.

The new findings, published January 9 in the journal Neurology, suggest that the combination of obesity (as measured by body mass index, or BMI) and a high waist-to-hip ratio may be a risk factor for brain shrinkage, the researchers said. Excess Belly Fat And Brain Shrinkage Findings of a new study that involved almost 10,000 people now provide evidence that having excessive fat around the middle may also be bad for the brain.

"Existing research has linked brain shrinkage to memory decline and a higher risk of dementia, but research on whether extra body fat is protective or detrimental to brain size has been inconclusive".

Researchers from Loughborough University and University College London discovered that people with a high body mass index (BMI) and high waist-to-hip ratio had brains that were 12 cubic cms smaller than people of a healthy weight.

The findings held even after researchers took into account other factors that can affect brain volume, including age, smoking and high blood pressure.

Links were also found between obesity and shrinkage in specific regions of the brain. Gray matter contains most of your brain's 100 billion nerve cells, while white matter is filled with nerve fibers that connect the brain regions.

The study observed 9,652 people with an average age of 55. "This will need further research but it may be possible that someday regularly measuring BMI and waist-to-hip ratio may help determine brain health".

After using a tape measure to calculate people's waist-to-hip ratio, scientists put them in MRI scanners to look at their brains.

Obese people carrying weight around their middle had the lowest average amount of grey matter, at an average of 786 cubic centimetres, compared to people of a healthy weight who had an average of 798 centimetres. Low-carb diets might be best for maintaining weight loss, study says Because the cause of a connection between brain volume and obesity is still unclear, perhaps something may be causing both, she wrote: "For example, if there are nutritional factors impacting brain volume, these same nutritional factors could be a direct cause of obesity". Hamer's findings confirmed that trend, since he found that people with high BMI readings and lower waist-to-hip ratios showed similar grey matter volumes to people who were not obese.
