Reporting in the New England Journal of Medicine, the PROPEL Study found that an intensive healthy lifestyle intervention—which included health coaches embedded in primary care practices working with patients to develop healthy habits—resulted in patients losing significantly more weight than those who received usual care from their primary care clinics, and they kept more weight off at two years later. The results show that successful weight loss can be achieved in primary care settings in a highly underserved population who have significant barriers to obtaining health care services.
