Objective: The objective of this Expert Consensus Statement is to assist clinicians in achieving remission of type 2 diabetes (T2D) in adults using diet as a primary intervention. Evidence-informed statements agreed upon by a multi-disciplinary panel of expert healthcare professionals were used. Methods: Panel members with expertise in diabetes treatment, research, and remission followed an established methodology for developing consensus statements using a modified Delphi process. A search strategist systematically reviewed the literature, and the best available evidence was used to compose statements regarding dietary interventions in adults 18 years and older diagnosed with T2D. Topics with significant practice variation and those that would result in remission of T2D were prioritized. Using an iterative, online process, panel members expressed levels of agreement with the statements, resulting in classification as consensus, near-consensus, or non-consensus based on mean responses and the number of outliers. Results: The expert panel identified 131 candidate consensus statements that focused on addressing the following high-yield topics: (1) definitions and basic concepts; (2) diet and remission of T2D; (3) dietary specifics and types of diets; (4) adjuvant and alternative interventions; (5) support, monitoring, and adherence to therapy; (6) weight loss; and (7) payment and policy. After 4 iterations of the Delphi survey and removal of duplicative statements, 69 statements met the criteria for consensus, 5 were designated as near consensus, and 60 were designated as no consensus. In addition, the consensus was reached on the following key issues: (a) Remission of T2D should be defined as HbA1c <6.5% for at least 3 months with no surgery, devices, or active pharmacologic therapy for the specific purpose of lowering blood glucose; (b) diet as a primary intervention for T2D can achieve remission in many adults with T2D and is related to the intensity of the intervention; and (c) diet as a primary intervention for T2D is most effective in achieving remission when emphasizing whole, plant-based foods with minimal consumption of meat and other animal products. Many additional statements that achieved consensus are highlighted in a tabular presentation in the manuscript and elaborated upon in the discussion section. Conclusion: Expert consensus was achieved for 69 statements pertaining to diet and remission of T2D, dietary specifics and types of diets, adjuvant and alternative interventions, support, monitoring, adherence to therapy, weight loss, and payment and policy. Clinicians can use these statements to improve quality of care, inform policy and protocols, and identify areas of uncertainty.

While the Western diet has evolved to become increasingly high in saturated fat, cholesterol, protein, sugar, and salt intake, nutrition education and training of health care professionals to counsel their patients on the hazards of such a diet has trailed behind. Primary care physicians have an opportunity to bridge the gap by providing nutrition and dietary counseling as key components in the delivery of preventive services. Increasing research points to the value of a whole-foods plant-based diet in combating chronic disease, yet the knowledge of health professionals about the topic is comparable to that of the general public. This education crisis is apparent in medical training with restricted time for dedicated lectures on nutrition, physical activity, restorative sleep, emotional well-being, and avoidance of risky substance use. Together, educators and learners are valuable catalysts for culture change in medical education, training, and clinical practice. Barriers to physician ability to counsel about lifestyle are many, but one that stands out is lack of training and comfort with counseling. This has implications for the training of health care professionals. American College of Lifestyle Medicine has a committee, Professionals in Training, composed of interprofessional and multidisciplinary students, residents, and fellows nationally and worldwide who are committed to expanding exposure to lifestyle medicine and implementation of lifestyle medicine in parallel curriculum and personal care.

Lifestyle medicine group sessions present a promising approach to clinical care. Based on decades of work in shared medical appointments and group visits for diabetes and other chronic conditions, a lifestyle medicine group session has the potential to provide a fresh and rewarding way of interacting with patients that fuels the practitioner and feeds patients' needs to spend time with the lifestyle medicine practitioner, connect with him or her, connect with others, learn the latest recommendations regarding healthy habits, practice these behaviors, and discuss their obstacles, motivations, and strategies for healthy living. The lifestyle medicine group session discussed in this article is a combination of group coaching, education, and group support.
