Remission of Type 2 Diabetes After Treatment With a High-Fiber, Low-Fat, Plant-Predominant Diet Intervention: A Case Series.

Background: Prevalence of type 2 diabetes (T2D) is rising, and its burden on the healthcare system remains a challenge. Consumption of a plant-predominant diet is a promising approach for achieving remission, which has emerged as a therapeutic target. Objective: To establish feasibility of achieving T2D remission with a plant-predominant diet in a cohort of free-living individuals. Methods: Patients referred to a wellness clinic were treated with a low-fat, whole food, plant-predominant diet while receiving standard medical treatment. Included patients were adults, mostly elderly, with HbA1c > 6.5%, with or without use of antidiabetic medications. Results: N = 59 patients were included in this analysis, with mean age 71.5 years (range 41-89). Twenty-two (37%) patients achieved T2D remission. Mean differences showed a significant decrease post-lifestyle change (T2) compared to prior to lifestyle change (T1) for the following outcomes [least squares mean difference (95% CI)]: BMI [-2.6 (-4.8, -.3)] kg/m 2 ; HbA1c [ -1.3 (-1.6, -1.0)] %; and fasting glucose [-29.6 (-41.8, -17.5)] mg/dL. No significant differences were observed for systolic or diastolic blood pressure, HDL, LDL, or triglycerides. Conclusion: A lifestyle-based treatment intervention promoting adherence to a plant-predominant diet and integrated as part of routine care can successfully achieve T2D remission in wellness clinic patients.
