Lol, I've never understood how one can 'forget' to eat 🙂 I'm one of those people who just stop to function as a human being unless I eat something every third hour 😀
Quite easily, i'm really good during the week, I eat at certain times and because I am out the house for work then gym/training I will usually have breakfast, snacks and lunch in my bag (plus keeping things in the office).
Come the weekend when the structure of my days is different I can often run about from once place to the next and realise at 4pm that i've not eaten anything other than toast since 6am.
