Suppose, say, the ketone bodies do rise. And they may not go from 0 to 100, but they go from 0 to 10, every day they go from 0 to 10. Then the second question is, 'What is the benefit of ketone bodies going to 10 from 0 on brain function or muscle function or heart function?' It's possible that maybe your brain may not get much benefit, but muscle and heart are getting some benefit.
