Welcome to DC!
Have a look around the forum. Most of us try to cook healthy (with the exception of bacon) and there are many recipes for all kinds of good stuff. Check out the Special Diets, Vegetarian, and General Cooking sections, along with Who's Trying to Lose Weight. There's also a lovely thread about Bento boxes. All really good stuff!
Also, the best exercise you can do is walking.
