The workshop featured invited presentations and discussions that explore what is known about current obesity treatment approaches and the challenges involved in implementing them, including their effectiveness (and how “success” is defined); payment for services; training of the workforce that provides the services; and health equity issues involved in treatment. The workshop agenda also addressed sustainable collaborations, new insights on implementing treatment-related interventions and policies, and research gaps in addressing treatment challenges. Participants discussed strategies that hold promise for progress in treating overweight and obesity.
