Hypertriglyceridemia remains an important component of residual risk for atherosclerotic cardiovascular disease. Current guidelines from the AHA/ACC recommend the initiation of a very-low-fat diet to treat persistently elevated triglycerides, whereas the National Lipid Association argues that a very-low-carbohydrate, high-fat diet is contraindicated in severe hypertriglyceridemia. In contrast, we report resolution of two cases of severe hypertriglyceridemia with implementation of very-low-carbohydrate ketogenic diets and intermittent fasting. Here, we describe two patients who have demonstrated substantial reductions in serum triglycerides, effectively reversing severe hypertriglyceridemia using unconventional dietary methods. Although anecdotal, these cases point to a critical lack of flexibility in current dietary guidelines that hinder their application in clinical practice.

Although anecdotal, these cases point to a critical lack of flexibility in current dietary guidelines that hinder their application in clinical practice. This study will provide a narrative review of the history of the clinical use of low-carbohydrate diets and give a practical example of how to implement a low-carbohydrate diet, with an emphasis on deprescribing medications. Low-carbohydrate diets have been used since the late 19th century to treat obesity and type 2 diabetes mellitus (T2DM). Recently, clinical research has validated the use of low-carbohydrate diets for individuals affected by obesity and T2DM, and these diets are included in several national clinical guidelines.
