In people with type 2 diabetes, regular aerobic exercise and weightlifting may reduce levels of fat in the liver by as much as 40 percent, according to Johns Hopkins researchers.
High liver fat levels are common in type 2 diabetes patients and contribute to heart disease risk.
The study included 77 diabetic women and men who were divided into two groups. For six months, one group did three 45-minute sessions of moderate aerobic exercise (bicycling, running on a treadmill, or brisk walking) and three 20-minute sessions of weightlifting per week. The other group didn't do any formal aerobic fitness or gym classes.
MRI scans showed that people in the exercise group had lower levels of liver fat by the end of the study (5.6 percent) than those in the non-exercise group (8.5 percent).
