Thiele: Pretty much. We have a graph that we show that shows the typical American diet, and I think the typical American diet is close to 60 percent carbohydrates, which I'm not sure is great, and then on the ketogenic diet about 90 percent of the calories come from fat. And so many people are concerned. "Gee, high fat. What does that do for risk of heart disease in later years?" And that has never been looked at, unfortunately, but the diet's been used for over 80 years in this country, and at least as far as I'm aware, there isn't really an increased cardiovascular risk. We do follow children extremely carefully when they're on this diet, since they're growing children and we're changing their nutrition and what we do see is that the lipids, the cholesterol will increase slightly when children start the diet but that tends to normalize over time.
