Counting Calories Helps Your Retirement Account, Too

Before those celebrating Thanksgiving reach for a second slice of pecan pie, they should consider this: A 55-year-old woman with Type 2 diabetes will pay an average of $3,470 more a year in medical-related expenses, or close to $160,000 in total, than if she didn't have the disease.

A one-time indulgence on a holiday certainly won't result in diabetes, but it's a good reminder that making the right food choices over time can have just as much of an impact on retirement savings as market forces and investment decisions. Minimizing the costs of aging is equally as, if not more than, important as maximizing retirement income.

Type 2 diabetes (along with its precursor, pre-diabetes) are prime examples since they're largely preventable by eating right and staying active. Those who suffer from them get hit financially because they don't necessarily shorten life expectancy; they allow people to live but with expensive health-related conditions — often incurring out-of-pocket costs that may not be covered by Medicare or insurance companies.

One study of Medicare beneficiaries showed that prescription medicine is the biggest driver of additional out-of-pocket costs for heart disease, diabetes and high blood pressure. Those with diabetes are also more likely to require costly organ transplants or long-term care, which Medicare doesn't cover.
