Brains of overweight people ‘ten years older’ than lean counterparts at middle-age
From middle-age, the brains of obese individuals display differences in white matter similar to those in lean individuals ten years their senior, according to new research led by the University of Cambridge. White matter is the tissue that connects areas of the brain and allows for information to be communicated between regions.
Our brains naturally shrink with age, but scientists are increasingly recognising that obesity – already linked to conditions such as diabetes, cancer and heart disease – may also affect the onset and progression of brain ageing; however, direct studies to support this link are lacking.

The team then calculated how white matter volume related to age across the two groups. They discovered that an overweight person at, say, 50 years old had a comparable white matter volume to a lean person aged 60 years, implying a difference in brain age of 10 years.
