WASHINGTON (Reuters) - Regular moderate exercise helps people with diabetes to reduce fat in their livers, in turn potentially preventing liver failure and heart disease, U.S. researchers said on Friday.

People with type 2 diabetes, the most common form of the disease and one closely tied to obesity, often have elevated liver fat levels and are at high risk for a condition called nonalcoholic fatty liver disease.

Diabetics who did a six-month program of cardiovascular exercise and weight lifting three times a week cut the fat in their livers by about 40 percent in the study by researchers at Johns Hopkins University in Baltimore.

They said the study, which used magnetic resonance imaging scans, is the first to show exercise can get fat out of the livers of people with type 2 diabetes.

"What we were able to demonstrate pretty definitively is that yet another benefit of exercise is to help reduce liver fat," Johns Hopkins exercise physiologist Kerry Stewart said in a telephone interview.
