Weight Loss May Not Help Hearts
Researchers stopped the large Look AHEAD (Action for Health in Diabetes) study early after it became clear that an intensive weight-loss program failed to reduce the risk of heart attack and stroke in people with long-standing type 2 diabetes. Participants had lost and kept off an average of 5 percent of their body weight for four years using a combination of exercise, diet, and medications. Yet, they were just as likely to have a heart attack or stroke as a group that received only education and diabetes support and lost just 1 percent of body weight. People in the weight-loss program had other significant benefits, including a reduced need for diabetes medications, fewer sleep disorders, improved mobility, and better quality of life.
