Just jogging or running the treadmill a few hours a week is enough exercise to at least keep your heart pumping. Find a buddy and make it fun! Converse and talk and laugh and people-watch while jogging indoors or outdoors and use each other to keep yourselves motivated.
As far as eating goes, just be adventurous. There's a bunch of different kinds of food you can cook and eat that are a lot healthier than what you describe is your diet so far. If that doesn't really suit you too much, try eating a small bowl of salad before every meal. The extra water inside the leaves will help curb those cravings later and you'll eat a smaller portion than before. That's one of my main points when trying to lose weight -- portion control. Every now and then go ahead and treat yo'self (HAH Parks and Rec) to eating that huge burger, but only after you've had yourself a bowl of salad and only eat half of it for lunch while saving the other half for later. That's really the key, especially when eating out at a restaurant where they give you such huge plates of food.
It doesn't really sound like you want into the whole muscle-building experience, so don't stress too much about lifting weights. One of the better ways to be fit and heart-healthy is just to make sure you don't fall behind in your cardio. Look into taking something like a kickboxing class to help keep your blood going while also getting some fun, stress-relieving activity in. Maybe go biking two days a week for a good 45 minutes each session with a friend? Offer to walk dogs in your neighborhood for a small fee and let them force you into walking and jogging around town! The best way to keep yourself motivated while exercising is to be creative and make things fun.
