As few as possible. I get the best ideas and the best personal "performance" at the maximum point of hunger, which I can bear (approx. 2 days) . No, i´m not joking. After this point i eat as much as possible, but only healthy food like fruits, vegetables, or, if necessarily, also a fat and juicy steak. Regular eating makes me too fast tired and slow-acting. I compensate the lack of nutrient with tablets (magnesium, calcium, iron, vitamine A, vitamine C, Vitamine E, selenium etc). Imo (and also my personal statement) I live so healthier, as if I would eat every day only artifical sh*t from "normal" super market food. Since everything became cheaper in the food sector, are also the quality of the products and their contents -very bad-.
