When I am in ketosis I get cravings and am tempted all the time. I wouldn't go out and buy foods such as chocolate etc, but if it was sat there in front of me I would be tempted. I have been in ketosis for 3 weeks a few months ago and still felt the same way. I am getting cravings for foods I probably wouldn't have bothered me before.. Freshly baked White bread and butter, treacle tart and custard, shortbread with milk chocolate on the top... I sometimes sit with a nigella cook book looking through the colour photographs! Looking but not tasting!
