How's this for weird?
I go to France for a fortnight. I eat what I like, when I like. I eat bread (lots of it), cheese (lots of it), and barbecues. I drink wine (less this time than usual, but you get the picture) and beer (lots of it).
You could say that my diet while abroad is completely unregulated. It's just what I feel like eating or drinking at the time, with no regard for calories, five-a-day, balance or 'sensible limits'.
So how come I came home half a stone lighter than when I left?
And how come this happens every time I go abroad?
Answers on a postcard, please.
