Multiple fasts to achieve your goal?

Just interested in stories of people who needed to do multiple fasts to accomplish their health goals?

Last year I did a 7 day and 14 day fast and I completed a 33 day fast in the summer but unfortunately am still dealing with the same issues. I've seen some improvements(eczema) but feel I need to do more fasting.

Thinking of doing a 40 day fast in the new year. My diet is good...plant based, whole foods only.
