I don’t know where you are reading about people being cured in 6 weeks but its not gonna happen unless you have a fecal transplant or get prescription antifungals.
If you think you can heal the body while building body mass this is not the best mindset to have.
It sounds like you are not very serious about getting better. You’ll just reverse the 6 weeks on the diet in less than a week afterwards if you continue to eat things like wheat, corn, dairy, etc. that constipate you and benefit the yeast. What supplements and food items are you planning to eat?
