This question was inspired by a casual conversation with friends the other night. Some of us had noted that women tend to eat smaller meals more often (snacks, fruits etc) while men eat larger portions more infrequently. Also, several of the women said to be sensitive to food withdrawal, getting very hungry after a few hours and experiencing low blood sugar symptoms (even fainting in one case) if not eating regularly, for example if skipping lunch. Men (including myself) seemed to be less affected, often skipping meals without noticing.
This was a highly unscientific investigation with a tiny sample size :) just based on our personal stories and friends we know. It could, of course, reflect attitude/perception/habits rather than actual biological differences. It should also be said that not everybody agreed -- some men also stated that they felt sensitive to food withdrawal. But there are of course known differences in metabolism between the sexes, so it doesn't seem entirely implausible. It might also be related to different body mass, muscle mass, etc.
So my question: is there any scientific evidence that women and men react differently to short-term food withdrawal? Here short-term would be, say, up to 24 hours, as when skipping breakfast and/or lunch. Are there any data on differences in blood glucose levels after food withdrawal, for example?
