Hello Rob. Let me know how you do with the water fast. I am trying to water fast every week from about Sunday 6pm til Tues 7am. I have grapes or juice as my first "meal" on the Tuesday. Fasting has reset my appetite incredibly. Supper this evening was rocket, avo, toms and dressing plus a tub of kale chips. A tub is 35 grams so not as big as it sounds!
