When Joe was still able to listen to podcasts, he listened to Terry Wahls talk about the Wahls Protocol, which allowed her to beat her progressive MS. He was convinced following the Wahls diet would help his PCS. There are 3 options - Wahls Diet, Wahls Paleo, and Wahls Paleo Plus. The Paleo Plus one is ketogenic, and he tried it for about a month and at the end of the month he was worse. He did want to stay on the straight Paleo diet and I help him by cooking for him this way. I think even that is too extreme, limiting things like oatmeal, brown rice, and legumes to only 2 servings per week. But he is an adult, and I am supporting what he wants to do. BTW, NOTHING has helped his condition for months, so the fact the diets are not helping is just more of the same.
