I can fairly happily eat healthily; weetabix/porridge for breakfast, cous cous/sushi/salad for lunch, meat/fish with veg/rice for dinner, it's the drinking that really prevents me from the whole toning aspect.
As much as I would love to have the elusive "beach body" as I did when I was younger (single), I'm not willing to go out, either for a casual afternoon/evening drink or an all dayer, and drink spirits and tonic water. I enjoy ale way too much.
Saying that, if I was to suddenly find myself single, I would probably turn into one of those people who spend every spare minute at the gym.
