The rising prevalence of obesity has become a major public health concern. In the past 20 years, the number of individuals who are classified as overweight or obese in the United States has doubled, currently encompassing almost two-thirds of the adult population (1). Obesity plays a major role in the development of diabetes, hypertension, cardiovascular disease, and many types of cancer (2). More recently, attention has been drawn to the negative impact of high body mass on cognition. In rodents, diet-induced obesity is associated with impairments in spatial learning (3). Among humans, large epidemiological studies have reported that obesity at midlife is significantly associated with higher incidence of dementia in old age. Individuals who were obese during middle age were five times more likely to receive a diagnosis of vascular dementia and three times more likely to develop Alzheimer's disease (4). Even in the absence of dementia, obesity has been associated with poorer memory and executive function in older adults (5). Consistent with these findings, higher BMI in middle age is also related to greater cerebral atrophy later in life (6). Read more: nature.com
