I don't agree, at all. I'm French and I love food, and cooking. I treat myself to a super meal before I start fasting... Never had a headache! I try not to hit the bottle too much tho, there's nothing worse than a hangover at a time you /can't/ eat ;-)

As for emergency supplies; on the contrary; just CLEAR the fridge, remove any temptation. I usually prepare/buy meals for my wife, but I try to make them quick to prepare and not too smelly. No need to torture myself smelling her lovely little dinner ;-)
