Abstract
SUMMARY: Traditional guidelines for type 1 diabetics do not restrict carbohydrates to improve clinical outcomes for patients. This paper highlights the favorable blood glucose control outcomes when a type 1 diabetic focuses on caloric intake from protein and healthy fats instead of the traditional carbohydrate-focused meals. We followed a male type 1 diabetic in his 20s adopting a ketogenic diet through a process of slowly lowering total daily carbohydrate intake. Diabetes-related biomarkers were measured throughout the process. Diabetes-related biomarkers saw massive improvements and ended up in the official non-diabetic range. Total daily insulin requirements dropped by 70%. The patient also experienced great improvements in his quality of life. This study demonstrates the possibility of improving diabetes-related biomarkers through dietary changes, which have positive effects on health outcomes in patients living with this disease. LEARNING POINTS: The adaptation of a ketogenic diet improved diabetes-related biomarkers in this patient. Diabetes-related biomarkers, such as HbA1c, are the main risk factors for developing complications in diabetics. The ketogenic diet is a feasible approach to minimizing the risk of developing complications in diabetics. Total daily insulin requirements dropped by 67% adapting a ketogenic diet. The patient experienced enormous changes in the quality of life after adapting to the new diet. The safe and physiological state of ketosis might be associated with additional benefits for the patient.
