We'd also like to acknowledge contributing editor Dr. Rohit Marawar, and the team at Sage Publishing.

Five Key Takeaways:

Effectiveness of Modified Atkins Diet (MAD): The research conducted by Dr. Manjari Tripathi found that 26% of the people who supplemented their drug therapy with the MAD experienced a more than 50% reduction in seizure frequency compared to only 2.5% of people who used only drug therapy. Importantly, some patients even became seizure-free.
Improved Quality of Life: Along with a significant decrease in seizures, patients following the MAD also reported improved quality of life and behavior.
Difference in Adherence Between Adolescents and Adults: The study found that adults were more likely to adhere to the diet than adolescents, possibly due to a combination of food preferences and possible differences in gut microbiota.
Potential Long-Term Effects of Ketogenic Diets: While ketogenic diets can be effective in managing epilepsy, there are potential long-term side effects to consider, such as vitamin and mineral deficiencies, bone loss, risk of nephrolithiasis (kidney stones), and hyperlipidemia (high levels of lipids in the blood), which may lead to cardiovascular and cerebrovascular diseases.
Approach to Weaning off the Diet: Dr. Mackenzie Cervenka suggests that weaning off the diet should be considered in a similar manner to removing anti-seizure medication. The decision should be made considering the side effects and the overall burden of the therapy on the patient. Abrupt discontinuation of the diet can result in an increase in seizures, hence the diet should be gradually reduced.

Dr. Adriana Bermeo (00:06):

Hello, and welcome to episode three of Epilepsy Currents podcast. I am your host, Adriana Bermeo. I am the senior podcast editor for Epilepsy Currents, the official journal of the American Epilepsy Society. It is my pleasure to welcome today's guest to talk about the use of ketogenic diets in the treatment of refractory epilepsy in adolescents and adults. First, I want to welcome our contributing editor for epilepsy current, Dr. Mackenzie Cervenka, who wrote a commentary titled "Keto Is Not Just For Kids: a randomized trial of a modified Atkins diets for adolescents and adults with anti-seizure medication resistant epilepsy". This was published online first in the March, 2023 issue of Epilepsy Currents. Dr. Cervenka is Professor of Neurology at John Hopkins School of Medicine. She's the medical director of the Adult Epilepsy Diet Center and the Adult Epilepsy Monitoring Unit. She developed the John Hopkins Adult Epilepsy Dietary Center in 2010 and has treated nearly 450 adults with epilepsy using ketogenic diet. Dr.Cervenka, welcome to Epilepsy Currents podcast.

Dr. Mackenzie Cervenka (01:16):

Thank you so much Dr. Bermeo for inviting me as a guest today at the Epilepsy Currents Podcast.

Dr. Adriana Bermeo (01:22):

It's a pleasure to have you. I also want to specially welcome Dr. Manjari Tripathi, who is the senior author of the publication that inspired this commentary titled "Safety, efficacy, and Tolerability of Modified Atkins Diet in Persons with Drug-Resistant Epilepsy." This was published in Neurology in March of 2023. Dr. Tripathi is a professor of neurology and epilepsy at the All India Institute of Medical Sciences, where she serves as director of the Epilepsy, Behavioral Neurology, and Sleep Medicine Programs. Dr. Tripathi, it's a pleasure to have you.

Dr. Manjari Tripathi (01:57):

Hi. Thank you. Great being here.

Dr. Adriana Bermeo (02:00):

Dr. Cervenka, I want to start with you. Our listeners may or may not be familiar with the concept of ketogenic diets for the treatment of epilepsy in adults particularly, but they may not know that there are different options for treatment. Can you please give us an overview of the principles of these dietary treatments and tell us what options can we can offer to our patients

Dr. Mackenzie Cervenka (02:21):

In our field? We refer to ketogenic diets for epilepsy actually as ketogenic diet therapies. And we do this to distinguish them from ketogenic diets that we typically hear about being used for weight loss or for other purposes, and that are not necessarily recommended or monitored by clinicians or treating teams. Technically, a ketogenic diet therapy is any dietary manipulation that can produce a state of nutritional ketosis, and that is a state where the body metabolizes fatty acids into ketone bodies. Those are beta hydroxybutyrate, acetoacetate, and acetone. There are a whole variety of ketogenic diet therapies, and these include what are called the classic or classical ketogenic diet. This was first described over one century ago. There are also modified versions of this classic ketogenic diet, specifically the Modified Atkins diet and a modified ketogenic diet. In addition to that, there is a low glycemic index diet or treatment, and that can also produce a state of ketosis, although it is not the primary goal of that particular diet, and any of these diets can be supplemented with medium chain triglyceride oil, and that is readily metabolized into ketone bodies. So that can be added to any of these other diets that I mentioned. Finally, these diets can also be combined with fasting, which also, encourages ketosis as well.

Dr. Adriana Bermeo (03:51):

Thank you so much, Dr. Tripathi. Do different options fit different demographics? Particularly I'm curious of why did your team choose to try specifically the modified Atkins diet in adults and adolescents with refractory epilepsy as opposed to other options as Dr. Cervenka was describing?

Dr. Manjari Tripathi (04:10):

So this is a very pertinent question. We need to give something which is acceptable, accessible, and affordable. Now, if you look at the traditional classic ketogenic diet, as Dr. Cervenka described it, it's a very restrictive diet, and it's rigid. It's rigid in terms that it restricts the calories and the fluids. It often requires weighing of food, at least in our center, the ketogenic diet requires the patient to be admitted for a washout and monitoring before the diet is started, whereas a modified Atkins diet does not restrict calories. However, it produces the same effect that is ketosis. So, it's more flexible, it's easier on the gut and the palate, and we know that adults and adolescence can be picky eaters and cho...
