See, I'm a big fan of intermittent fasting: during the school year (when I teach), I fast from bedtime to 4pm or so the next day. No food, except for coffee, during the day, and I feel far better and more productive than when I eat during the day. I get enough calories during the evening, and I'm definitely not starving myself (if you saw me in person...), but there's quite a bit of research into IF that shows its benefits.
I don't fast in the AM but typically don't eat a solid meal until early afternoon. A piece of wheat toast with peanut butter and some black coffee gets me going just fine. I graze throughout the day mostly. The 3 square meals a day baffles me, but that could be because I like being able to feast at night and not worry about empty beer calories haha.
