Ketogenic Ratio
The mathematical ratio of fats to carbohydrates plus proteins in the ketogenic diet, typically expressed as grams of fat per gram of combined carbohydrate and protein.
Full Definition
The ketogenic ratio is a fundamental parameter in ketogenic diet therapy for epilepsy, representing the proportion of fats to the combined weight of carbohydrates and proteins. Common ratios include 4:1, 3:1, and 2:1, with higher ratios producing greater ketosis. The ratio is carefully calculated by dietitians to achieve optimal seizure control while ensuring adequate nutrition for growing children. Adjustments to the ratio may be made based on seizure response, tolerability, and nutritional status.
Usage
Usage note: Always expressed as a ratio (e.g., 4:1) rather than a percentage.
