I have PD and have been very interested in trying ketogenic diet.
Since 10 weeks ago I started reducing carbo foods drastically, take two table spoons of coconut oil daily and obtain most of my calories from meat, vegtables and little fruits. So it is a far shot from strict ketogenic diet but never the less I noted a remarkable improvement in energy and mood. however, my main PD complain which is tremor did not improve at all.
wish you good health and companionship in our forum
