Even if reviving that six-pack from your twenties no longer seems feasible, keeping weight off the midsection is still a worthwhile goal into your middle age. Researchers have found that those who were overweight at the age of 50 were at a higher risk of developing Alzheimer’s disease. In fact, for each unit increase in body mass index (BMI), the indicators of Alzheimer’s seemed to appear about seven months sooner. While previous research has already determined obesity increases Alzheimer’s risk, this is one of the first studies suggesting that obesity can speed up how soon it begins as well. To maintain a healthy weight, the National Institute on Aging suggests incorporating a Mediterranean diet rich in fruit, vegetables and ‘good’ fats from olive oils and fish, as well as exercising for 30 minutes most days of the week. Do you find that keeping off weight gets harder with age? What weight maintenance strategies have worked for you? Tell us in the comments!
