Randomized trial compares ketogenic diet costs to standard diets in adults, highlighting affordability implications.
Key Points
This study aims to evaluate the cost-effectiveness of various ketogenic diets compared to typical dietary standards in adults with epilepsy.
Generated seven-day meal plans for males and females aged 31-50 years for five different diets.
Obtained prices for meal plans from three different supermarkets.
Compared weekly costs of the classical ketogenic diet, modified ketogenic diet, specialty modified ketogenic diet, national dietary guidelines, and a typical Australian diet.
The classical ketogenic diet was $70.07 AUD for females and cheaper than the national dietary guidelines ($99.23 AUD).
For males, ketogenic diets ranged from $94.81 to $119.60 AUD and were more expensive than the typical Australian diet ($82.98 AUD).
Modified and specialty modified ketogenic diets increased food costs by 9%-31% for females and 26%-44% for males compared to a typical Australian diet.
