If you cheat you only cheat the one that is most important.
YOU.
Why cheat?
If you need something sweet eat something LC not real sugar.
If you eat enough sugar it will defininatly kick you out of Ketosis. Then it will take you 48 hours to get back in ketosis.
Some people can handle the polyols (sugar alcohols) without too much problem. If you stall look hard at polyols.
