Grey matter is the ‘thinking part’ of the brain, and consists of brain cells involved in muscle control, seeing, hearing, memory, emotions, and speech. The white matter is the ‘nerve motorway’ — the material that connects these cells to each other. Being overweight can change the way we think, too, affecting our judgment and making us crave even more high-calorie fodder. As a result, we seek out a food ‘fix’ in the same way a drug addict needs narcotics. With a quarter of adults and one in seven children in England thought to be obese — classified as having a Body Mass Index (BMI) of more than 30 — the implications are alarming... The researchers, who examined brain scans of nearly 100 people aged over 70, concluded the brains of overweight people were on average eight years older than those of their healthy counterparts. ‘We based this on the fact that the average person loses 0.5 per cent of their brain a year,’ says Professor Thompson.
