While one highly publicized study suggested that those who are moderately overweight have slightly longer lifespans, other studies, such as this one at Oxford University, associated being moderately overweight with a decreased lifespan. The overweight, or obese, are said to experience lifespans 10 years less than average according to the Oxford study.
Weight loss is a common concern for many older seniors. It may become necessary to eat every two or three hours, eat larger portions at the time of day when your appetite is strongest, incorporate healthy fats into your diet, make healthy smoothies for snacks, and have a healthy bedtime snack. Additionally, if you smoke, then speak to a healthcare professional about resources that can help you quit. (Smoking can reduce your appetite and ability to taste.)
Elderly people who live alone and are left to prepare food by themselves often have bad outcomes. Cognitive and physical problems often cause seniors to become unable to prepare adequately nutritious or filling meals. Eating almost every meal in isolation can also exacerbate anxiety, loneliness, and stress. In other words, constantly eating alone can put seniors at risk.
