Myth #8: Only overweight people get diabetes.

Here's the skinny on this one: Many people who have type 2 diabetes carry excess pounds, and some are obese, but many elderly people with the condition aren't particularly overweight. If you or the person you're caring for needs to shed some weight, it may be motivating to learn that even modest weight loss through healthier eating and increased activity can help keep long-term complications at bay. But diabetes doesn't discriminate: Even Slim Jims can succumb to the disease.
