The Ketogenic Diet for Type 2 Diabetes Management

Introduction: Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder characterized by insulin resistance and elevated blood glucose levels. The management of T2DM typically involves lifestyle modifications, pharmacotherapy, and dietary interventions. Currently, it is widely accepted that ketogenic diets are efficacious in weight loss interventions. Over 90% of diabetic patients are overweight or have obesity, and there exists a clear connection between type 2 diabetes and obesity. Studies have demonstrated that even a moderate 5% reduction in weight can notably enhance HbA1c levels in patients with obesity and diabetes. The ketogenic diet (KD), a low-carbohydrate, high-fat diet, has gained attention as a potential therapeutic option for T2DM management. This comprehensive review aims to evaluate the evidence regarding the efficacy and safety of the ketogenic diet in the management of T2DM [1]. Methods: This review systematically analyzes existing literature, encompassing studies published from January 2000 to June 2023, retrieved from databases such as PubMed and Medline. Additional data sources include national health surveys conducted by governmental and international organizations. Through rigorous study selection criteria, this review incorporates methodologically sound research while excluding studies with limited intervention duration, non-peer-reviewed sources, or focus on type1diabetes. Results: Numerous studies, including randomized controlled trials, have investigated the effects of the ketogenic diet on T2DM. The findings suggest that the ketogenic diet may improve glycemic control, reduce insulin resistance, and facilitate weight loss in individuals with T2DM. Additionally, favorable changes in lipid profile, including reductions in triglyceride levels and increases in high density lipoprotein cholesterol, have been observed. However, concerns have been raised regarding the long-term sustainability, potential nutrient deficiencies, and adherence challenges associated with the ketogenic diet [2]. Conclusion: In conclusion, the available evidence suggests that the ketogenic diet may have potential benefits in the management of type 2 diabetes. However, due to the limitations of existing studies and the need for further research, it is important to approach the implementation of the ketogenic diet in T2DM management with caution. Clinicians and individuals with T2DM should carefully evaluate the potential risks and benefits, and personalized approaches should be employed to optimize the therapeutic outcomes.
