I spent the week eating a bunch of indian and chinese food. Problems cropped up when friends would want to drop by fast food places like mcdonalds or mos burger or pepper steak, which means that you're eating dessert now (ice cream) and getting actual food later.
Aside from the time-shifting, one part of my brain complained about not getting enough protein, so I ate less rice and more non-rice-based noodles. The alarm wouldn't quiesce, so I ignored it. Not sure whether my body actually had a shortage, or just that the new food mix had thrown it for a loop. Monitoring fail....
Although, there's probably a japanese toilet that tells you whether you have enough protein in your diet.
