Majority of participants in trial lost weight and reduced medication use.
Weight loss and control of blood sugar can reduce the risk of complications in patients with diabetes, but this is difficult for many to achieve. A UC San Diego School of Medicine randomized controlled trial of obese adults with type 2 diabetes suggests that participants enrolled in a community-based structured weight loss program are able to shed more pounds, improve blood sugar control and reduce or eliminate insulin use and other medications compared to a control group.
“Support and a tailored lifestyle intervention have been shown to reduce cardiovascular disease risk factors and adverse outcomes in people with diabetes,” said Cheryl L. Rock, Ph.D., R.D., professor of family and preventive medicine and principal investigator of the study. “However, most overweight individuals with type 2 diabetes do not receive this degree of support for changes in diet and physical activity to promote weight loss in their clinical care, due in part to constraints of time and training for most health care providers and clinicians.”
The results of the study, published in today’s (April 23) online issue of Diabetes Care, found that 72 percent of participants on the weight loss program that included portion-controlled foods and personalized counseling were able to change their insulin use compared with 8 percent of the control group. Similarly, other diabetes, cholesterol and blood pressure drugs were decreased or discontinued more often among the weight loss program enrollees.
According to the Centers for Disease Control and Prevention, 35 percent of adults in the United States are obese and 8 percent of adults are affected by diabetes.
“Weight loss is a primary strategy for successful management of type 2 diabetes due to its impact on glycemic control and improvements in cardiovascular disease risk factors,” said Rock. “These study results suggest that patients not only lose weight on structured commercial weight loss programs that include behavioral modification and individual support, but that this weight loss translates to significant improvements in diabetes control and cardio-metabolic parameters.”
