Other men lose weight to feel better about themselves, before going on holiday or for health reasons. My husband announces this morning that the reason he has been loosing weight the last few months is...so he can look good in the birth pool. (As if he is going to get in with me!!!)
This actually tops the comment he made last weekend to a friend. When discussing when we would see her next (likely to be later this summer/early autumn) he said to me, "Who knows, you could be knocked up again by then."
