Almost 10% of the US population has diabetes, with another 34% in a precarious state of prediabetes. Research demonstrates that lifestyle interventions, particularly those incorporating personalized nutrition therapy, produce clinically meaningful improvements in diabetes. Integrating this research foundation into the clinical setting is key. A recent study describes a 20-week clinical trial conducted by an endocrinology private practice in Washington, DC. Utilizing the waiting room to deliver weekly group-based nutrition education classes, the study examined the effects of two eating plans, low-fat vegan and portion-controlled, on cardiometabolic outcomes in patients with type 2 diabetes.
