Enara Health is building a data-driven platform and network to scale obesity treatment. Based in San Mateo, Calif., and operating since March 2015, Enara Health offers unique hybrid digital and in-person weight loss programs based on precision medicine. By combining mobile technology with health care visits and providing patients with personalized physician-driven medical weight loss programs, Enara Health routinely helps patients lose—and keep off—more than 15% of their baseline weight, which is far greater than the results seen with other e-health and m-health interventions.
