Having extra body fat, especially around the middle, may be a risk factor for brain shrinkage, according to a study that looked at the effects of greater body mass index (BMI) and waist-to-hip ratio.

The researchers found that a higher level of obesity was associated with lower levels of grey matter volume in the brain.

‘Obesity was associated with lower gray matter brain volumes,’ the authors say. ‘It is unclear whether structural brain abnormalities drive obesity or whether obesity induces changes in gray matter volume that play a mechanistic role in future risk of neurodegeneration.’

The study analysed data from more than 9,000 people aged 40-69 years
