The MKD is similar to the MAD (modified atkins diet) but has a more structured approach. It is restrictive, but has a slightly more generous carbohydrate allowance (especially when starting the diet) which is evenly spread over meals and snacks. Your ketogenic team will decide on the amount of carbohydrate suitable for you. Food choices are designed to be flexible and when undertaking the MKD guidance and structure will be provided on food selection and portion sizes by use of an ‘exchange ‘or ‘choice’ system for foods providing fats and carbohydrates. These are typically weighed out, especially at first. This, together with advice on moderation of protein foods, and meal plans, helps ensure an appropriate macronutrient and energy intake for you or your child.
