Start small. You may want to try my game [1] for that.

Do at least some short&easy workouts and gradually-very gradually raise the bar. Your goal is to find and carefully grow a joy in yourself of doing exercises b/c of having healthy body. Just listen to your body while doing workouts and in 1-2 weeks time you'll see a slight hint of improvements - catch it and babysit it into a habit of regular exercising. If you can keep it for 2 month, you can keep it forever.

Proper nutrition is a huge topic by itself... There are few simple rules thought: If you don't have specific conditions (consult your doctor) than just try to eat a little bit less energy than you spend, try to get used to occasional hunger (calories deficit is generally helpful for a well-being). Also prefer a food with a low glycemic index (google that term if it's new for you).
