Weight loss

My shorts keep falling down maybe I have lost a bit of weight? They're so loose, I have to keep pulling them up, I must have lost weight I suppose I have been eating quite healthily and skating a bit and well not really eating healthily but drinking a lot instead of eating which is sort of a bit almost like a diet and probably means I'd lose weight, except aren't there lots of calories in beer or something? But still they're so loose maybe I should buy a belt...oh no wait my fly is undone.
