You should notice improvements immediately, except you’ll feel pretty bad with die-off. After 2-8 weeks you’ll feel like a different person and will gradually start to heal. After 6-12 months on the diet you will hopefully start to become symptom free. Everyone has a different rate of healing of course and how much you progress is completely up to you and what you decide to plan for your treatment. Going to a naturopathic doctor can significantly reduce your turnaround time.
