What worked for me was doing two/three days of juice fast first. During this time you clear the colon. Once "empty" it is much easier to maintain the fast.

I usually the water fast for two/three days, and then do one day of dry fasting. If it goes really well I extend it by a day of two.

To get back to my regular diet (which is mostly "WFPB" https://www.doctorsfornutrition.org/general-public/what-is-w... ) from a dry fast, I usually take one day of fruit-only. This to gently start the GI back up.

I cannot recommend doing some fasting yourself enough. It really changed my attitude to food and "feeling hungry". I made some personal bests in sports while fasted!
