What makes me feel the absolute best is waiting till around noon for my first meal. I'm doing ~8-16 Intermittent fasting routine. I feel energetic all morning and it totally eliminated the mid-afternoon sleepy feeling. I've never been hungry first thing in the morning anyway, so it made sense for me to try. If I do force myself to eat something in the morning, I get hungrier sooner and then I find myself looking for the George Costanza Desk soon after lunch.
Some of you may die, but that is a risk I'm willing to take.
