(Fox News) A study of nearly 2 million people in Britain suggests an unexpected protective effect against dementia: obesity in midlife.
The research, published Friday in the journal The Lancet Diabetes & Endocrinology, linked a 34 percent increased risk of dementia among people who had a BMI of less than 20 kg/m2. A BMI of 18.5 is considered to be underweight. Meanwhile, the study findings linked very obese people— those with a BMI greater than 40— to having a 29 percent decreased risk of dementia.
