According to the Kaiser Permanente study, published online in Diabetes Care of the American Diabetes Association journal, losing weight soon after the diabetes diagnosis helps to better manage the disease and control it. Therefore, it is very important to keep a special diabetes diet and carefully choose the types of foods that the diabetes patient can eat.

The story fromt the American Diabetes Association shows how early weight loss soon after the diabetes diagnosis can help to manage the disease.

People who lose weight soon after being diagnosed with type 2 diabetes are up to twice as likely as those who don't to achieve blood glucose and blood pressure goals, even if the weight comes back, according to a study published online today in the journal Diabetes Care.

Researchers at Kaiser Permanente's Center for Health Research (KPCHR) in Portland, OR, found that losing a moderate amount of weight (a mean of 9.8 percent of body weight) within an average of 18 months of diagnosis helped people with type 2 diabetes to achieve blood pressure and blood glucose levels within the target range. Those improvements remained three years later, even if the weight returned.

"What's critical here is that early weight loss may provide lasting benefits for risk factor control that in turn can reduce diabetes-related complications and mortality," said the Kaiser Center's lead researcher, Dr. Adrianne Feldstein. "We've known for a long time that weight loss is an important component in diabetes treatment and prevention. Now it appears there may be a critical window of opportunity following diagnosis in which some lasting gains can be achieved if people are willing to take immediate steps toward lifestyle changes."

Nearly all adults with type 2 diabetes are overweight and more than half are obese, a condition that is associated with poor blood glucose control and other cardiovascular risk factors. Previous research shows that losing weight and maintaining a healthy weight helps people with diabetes improve glycemic control, reduce blood pressure and improve blood lipids.

"These findings suggest that, even in the face of weight regain, losing weight can have long-lasting benefits in type 2 diabetes," the researchers concluded. "The therapeutic advantage achieved through weight loss is exceedingly important, given the close connection between glycemic and blood pressure control and cardiovascular outcomes."

Gregory Nichols, another author on the study, said people with type 2 diabetes may also be more motivated to lose weight when they are first diagnosed, and that doctors should encourage them to do so during this important window of opportunity.

However, he said, "We don't know if the initial weight loss increases the body's sensitivity to insulin, or if the sustained lifestyle changes are the reason for the long-term health benefits. What we do know is that losing weight reduces the risk factors that often lead to heart disease, blindness, nerve and kidney damage, amputations and death."

The study, a retrospective cohort, used data from the clinical medical records of 2,574 HMO patients aged 21-75 who had received a diagnosis of type 2 diabetes between 1997 and 2002. Patients were followed over a 48-month period. The study was supported by a grant from the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK).
