I don't know if "Fasting" ALONE will cure internal parasite infestations...Remember they can live inside and Feed off your Blood and be happy. So even if you stop eating food the Worms will stay attached to your Organs and suck on your Blood...Internal parasites are the smartest organisms in the world. They will try to out-smart you in order to live. Internal parasites can "mimick" internal oragans...
HumaWorm is one of the best & least expensive healing formulas out there for internal parasites..It may take years to Kill all the Eggs and Adult worms from head to Toe but it will be worth it in the long run.
Develop a plan and stick with it. Everyone is not infested with parasites but some of us are. Some form of daily meditation or prayer and patience is the only way you're going to follow through with a plan to rid your body of internal parasites..
