[quote]Though its exact mechanism is uncertain, the diet appears to work by throwing the body into ketosis, forcing it to burn fat rather than sugar for energy. Breakfast on the diet might consist of bacon, eggs with cheese, and a cup of heavy cream diluted with water; some children drink oil to obtain the fats that they need. Every gram of food is weighed, and carbohydrates are almost entirely restricted. Breaking the diet with so much as a few cookies can cause seizures to flare up.
For the British trial, the researchers enrolled 145 children ages 2 to 16 who had never tried the diet, who were having at least seven seizures a week and who had failed to respond to at least two anticonvulsant drugs.
One group began the ketogenic diet immediately. The control group waited three months before starting it. In the first group, 38 percent of the children had seizure rates reduced by half, compared with 6 percent in the control group. Five children in the diet group had reductions exceeding 90 percent.
