Just eat healthy stuff and don't eat a lot. If you are trying to kill parasites then you don't want to eat foods that they like. They like all the bad stuff. Eat as much raw foods as possible and limit things like beef and pork, fats, sugars, etc. It's just common sense really. Exercising and drinking water is very helpful also.
The parasite cleanse can take quite awhile depending on the level of infestation, so you have to eat. Sometimes I think it's better to not change your eating habits too much. Die-off can be tough enough without having to deal with the affects of a major diet change. The parasites did not get there overnight so they probably wont leave overnight either.
I'm using Para-buster and I will probably stay on it for 40 days.
