Low carbohydrate high fat (LCHF) diets are an effective means for people with type 2 diabetes (T2D) to improve glucose control and reduce medication use, however there are still many unanswered questions about the diet. For example, there is much confusion as to what actually constitutes an effective LCHF diet in practice and little is known about the perceptions and experiences of T2D patients who follow an LCHF diet. The physiological mechanisms of how the diet improves glucose control and affects health are not clearly understood. Understanding these mechanisms is important if LCHF diets are to be widely accepted for managing T2D because there are still concerns that the high fat component of the diet will negatively impact other aspects of diabetes pathology.
