I chose to have breakfast but I agree that we are brainwashed into what we need. Primarily, I think, by the food industry. We do NOT need to snack for example. Our blood sugar won't drop if we don't eat for two hours.

I've not snacked between meals since May 2012 and I'm still alive and haven't had a hypo. On my second fast day and I think that one reason why I've not had problems is that I am used to leaving gaps between meals. This is just one step up.
