A commentary on these issues can be found on the Dr. Andreas Eenfeldt – Diet Doctor website: Inaccurate news stories suggest low carb causes atrial fibrillation. Diet Doctor
In the following case study authors concluded that the implementation of a ketogenic diet triggered an increased number of arrhythmia events in a patient with congenital Long QT syndrome (LQTS)
In this case report two children are presented with growth failure using carbohydrate restriction in type 1 diabetes. In both cases they present as hypocaloric with no details apart from macronutrient percentage. These cases highlight the necessity of a well formulated diet in children along with sufficient monitoring and diet adjustments as required.
The following study demonstrates that a nutritionally sufficient meal plan can be implemented using a low carbohydrate approach.
Studies in children with epilepsy constitute the majority of the data on this subject. Of note is that the medical ketogenic diet for epilepsy may be lower in protein due to high ketones being of therapeutic importance for seizure control (often 4:1 or 3:1 ratios).
In the following paper, appropriate growth was maintained in the ketogenic diet group consisting of participants less than 2 years old, which is a critical period for growth.
This study of older children with epilepsy or GLUT1-DS found the majority of participants (80%) maintained or improved their weight at one year follow-up.
For completeness the following articles are included. In both these cases a thiamine deficiency was found and recovery of optic nerve function occurred with appropriate treatment.
