Having a pot belly in middle age could raise people's risk of developing Alzheimer's disease. Dr Sudha Seshadri from Boston University School of Medicine led a study of over 700 people with an average age of 60. The participants had their body-mass index, waist-to-hip ratio and abdominal fat measured and had MRI scans to measure the volume of their brains. The higher people's body-mass index - i.e. the more overweight they were - the lower the volume of their brains was. There was a stronger connection between visceral obesity - a pot belly - and a reduction in brain volume.
