A friend who went on a world cruise put on 31/2 stone, despite doing far more exercise than he ever did at home. As this was on Cunard he had sensibly taken two dinner suits with him, of increasing sizes. When he got back, the first 21/2 came off easily and fairly rapidly without doing anything in particular. The last stone was a different matter. But, anyway, the point is simply by eating normally for home, rather than as one does on a cruise, it usually disappears quite easily. 🙂
