Prevention of Type 2 Diabetes: The Role of Intermittent Fasting

Abstract

Despite the progress in treatment options and improved understanding of pathophysiology, type 2 diabetes remains one of the costliest and most harmful global chronic diseases. The current guidelines encourage physicians to fight an uphill battle and react to an incubated disease state that has been propelled forward by clinical inertia. The authors completed a literature search of PubMed, ScienceDirect, and NIH, searching with the terms intermittent fasting, type 2 diabetes, and prediabetes, and excluded studies related to religion-based fasting. There is emerging evidence that intermittent fasting could be an option to aid in weight loss, reduce hepatic steatosis, and lower the level of biomarkers such as fasting glucose while improving insulin resistance. If incorporated into the lives of patients with risk factors for type 2 diabetes, intermittent fasting could prove to be a cost-effective and efficient tool for preventing this insidious disease. This clinical review examines current evidence supporting the implementation of this lifestyle to prevent the onset or exacerbation of type 2 diabetes and the hurdles that must still be overcome for physicians to confidently prescribe this to their patients.
