And having had quite a bad and not very healthy day, during which I feel like I ate a lot, and some serious crap, it turns out that a day of over-eating unhealthy crap for me is actually 1300 kcalories. So why the flippity flip do I gain weight so consistently? I'm 5 ft 6 and used to have the metabolism of a horse (which my three oldest children currently exhibit, for now anyway...) If I even attempt to eat what others consider normal I gain 2+ kg a month. In fact since DD3 was born just under 4 years ago I've gained nearly 10 kg, and not by eating all the pies neither! Gah!
