Losing weight is easy

Over the past few weaks I've noticed that I've lost even more weight than when I first came to London. The reason for this is simple, I dont eat enough. No breakfast, a sandwich or two for lunch, and wahtever I have the energy to cook in the evening (quite often this is not much).

The problem here is that I dont really want to lose weight, but have no choice, breakfast is just too much effort for the morning, lunch is always good, but theres only so much you can eat, and after a long day at work, I dont really feel like standing in front of the stove cooking something.
So it normally ends up being a pizza, chiproll from the fish and chips shop, pasta, or toast, of which none are nearly filling enough.
