What's everyone doing to keep their weight down? Diets, exercise?

We walk for 30 minutes 5 times a week....try to eat fresh healthy meals most of the time....we do have take away once a week though....we also enjoy a few light beers at the weekend so we're not real health freaks.
But our weight stays around the same so I think the walking really helps with that...plus we really enjoy going for a walk and you feel so much better afterwards.

Walking is good exercise, I also like to go swimming when I can!

Climbing up the stairs to my computer several times a day keeps me trim.

Seriously though, I really ought to do more exercise. I do have an exercise bike but don`t often use it. And, I tend to like most of the `wrong` foods.

I must organize a workable health regime for myself one day.
