It's no secret, obesity rates are booming, and that spells trouble your clients' retirement. How? A report by The Trust for America's Health and the Robert Wood Johnson Foundation cites a recent study that shows older adults who are considered obese can live just as long as their more svelte counterparts, but will spend more on health care. Once your chubbier clients hit 65, they could be paying an additional $1,486 per year for health care compared to average-weight individuals; some studies have found obese seniors could pay as much as $6,192.
