The diet is hard for parents to start their child on, as it cuts out most foods that kids love, but it is a healthy diet that has helped many children with their seizures.

Basically, the ketogenic diet forces the body to burn fat around the clock. By burning fat for energy instead of glucose, the diet is able to prevent seizures from occurring. The diet doesn't work for all children, but it is recommended by many doctors that children who suffer seizure disorders try the diet to see if it will help.

The diet consists of low calorie intake and high fat consumption. The diet is about 80% fat and 20% carbohydrates and proteins. 

The food and liquid intake must be carefully measured for each meal or snack for each individual person. Everyone is different, so the diet isn't 100% the same for each person.

Never start a child on the ketogenic diet without medical guidance, as the meal plan will be a little different for each child. Plus, the child needs to be carefully monitored by an experienced team.

There are some potential side effects with putting a child on this diet for seizures. Your child may or may not be affected, but it's always good to know what the potential problems are before you get started, so that you know what to watch out for.

Just remember to keep a close eye for any irregularities because some of the side effects can go away if caught early, and the child can continue on with the diet.
