Ketogenic diets are not recommended for patients with Type 1 Diabetes due to increased risks of hypoglycemia, diabetic ketoacidosis (DKA), and potential bone health issues.

Avoid ketogenic diets if you have T1D. The risk of diabetic ketoacidosis (DKA) and hypoglycemia is too high. Focus on balanced meals with nonstarchy vegetables, whole foods, and careful carbohydrate counting instead of extreme restriction.

ModerateRefutesMEDIUM confidence
However, there is not yet sufficient evidence to recommend the safety of a ketogenic diet in T1D, with ongoing concerns for the risk of hypoglycemia, reduced glycogen stores blunting the response to glucagon [38], and the risk of relative insulin deficiency leading to DKA [39].

Why this rating

Based on mechanistic concerns and lack of sufficient safety data, rather than large-scale adverse event trials.
