Washington: Researchers found that obese teenagers who reduced their body mass index (BMI) by 8 percent or more had improvements in insulin sensitivity, an important metabolic factor related to the later development of type 2 diabetes. The teens followed a family-based, lifestyle-modification weight loss program that offers the potential to become a broader model.BMI is a measure of body weight adjusted for height."This threshold effect that occurs at 8 percent suggests that obese adolescents don`t need to lose enormous amounts of weight to achieve improvements," said pediatric endocrinologist Lorraine Levitt Katz, M.D., of the Diabetes Center for Children at The Children`s Hospital of Philadelphia. "The improvements in insulin sensitivity occurred after four months of participating in a lifestyle-modification program," Katz stated.
