Diabetic Ketoacidosis in Young Adults with Type 1 Diabetes: The Impact of the Ketogenic Diet-A Narrative Literature Review.

(1) Background: diabetic ketoacidosis (DKA) remains one of the most serious acute complications of type 1 diabetes, especially among young adults. At the same time the ketogenic diet, characterized by high fat and very low carbohydrate intake, is becoming increasingly popular, raising concerns about its appropriateness and safety for individuals with type 1 diabetes, (2) Methods: a literature review was conducted using MEDLINE and SCOPUS databases, complemented by additional searches in Embase, Cochrane Library, and Web of Science to ensure broad coverage of both international and European studies with the focus on keywords including "diabetic ketoacidosis", "type 1 diabetes", and "ketogenic diet". The most relevant and up-to-date studies were selected to evaluate both risks and potential clinical applications of this diet in T1D in young adults, (3) Results and Conclusions: While nutritional ketosis under controlled conditions is typically safe, individuals with T1D, especially young adults, may be more vulnerable to DKA due to factors such as inconsistent insulin administration, lack of ketone monitoring, and lifestyle changes. Reports of euglycemic DKA further highlight the importance of regular ketone tracking, even when blood glucose appears within target ranges. Although low-carbohydrate diets may offer improved glycemic profiles, their use in young adults with T1D must be carefully evaluated, emphasizing individualized care plans, close metabolic monitoring, and comprehensive patient education. Ongoing research is essential to clarify whether ketogenic diet can be safely integrated into diabetes management in this population.
