Not all people who have type 2 diabetes are fat as many people suppose. Personally I am 5'6", weight 142 lbs and I am a type 2 diabetic. I could stand to be slimmer but I am not fat. People are often surprised to discover I am a diabetic. Here is a statistic for you - 20% of people with type 2 diabetes are not overweight! So don't think just because you aren't 'fat' you are protected from diabetes. Ruth Loos, Ph.D., leading researcher for the British Medical Research Council Epidemiology Unit, says, "Regardless of your size, aim for 30 minutes of moderate exercise most days of the week and eat a diet rich in whole foods. If type 2 diabetes runs in your family, ask your doctor about glucose testing.
