I've done it myself (zero calorie water fast) and it worked for me (n=1). The difference between day two and day three is stark. It's free and easy to try. Maybe check with your physician first if you are on medications or have health issues. If the question that you are trying to answer is "will this work for me?" then there aren't any papers that I know of which will answer that. :)
You can do a zero sugar, zero carb fast for three days. Once the gut bacteria starve and die the cravings disappear. The first two days are a bit tough.
