AS BELLIES GROW, BRAINS SHRINK
BELLY fat has been linked to a new hazard. It seems people with excessive fat around their middles tend to have less grey matter in their brains than people of a healthier weight.
Researchers from Loughborough University and University College London measured the
BMI and waistto-hip ratio of 9,652 middle-aged people and used MRI to scan brain volume.
Those with a BMI of 30 or more (making them obese) and a high waist-to-hip ratio had a significantly lower average grey matter volume than those of healthy weight.
Scientists are, however, unsure if brain shrinkage drives obesity or vice versa. Poor diet and lack of exercise could be responsible.
