It's not so much a change of diet you need, it's a change of lifestyle.
A thread like this will probably just get comments saying you should eat less or do exercise, but it's a bit more than that. You have to make a conscious effort, for yourself and not just because some doctor or whatever told you, to take on a different way of life. The mental shift in that is more important than you'd think.
It's not all mental motivation mumbo jumbo though. It's hard work. There's a reason we look up to fit people. It takes effort to be just that. Start the day of with some light exercise to get the blood flowing. It's quite ideal to start the day that way, because not only does it wake you the fuck up, the morning shower afterwards takes care of the sweat you might have worked up (and you better have worked it up).
Eating less? Depends on what you eat, really. Lay off the snacks. Not all the time, of course. You're human, a snack every now and again is fine. Get a balanced diet going. Try and look up information about nutrition and follow it. Soda? The less the better. That's actually the worst thing most people indulge in, especially considering how frequently they do so. The best choice of drink is water. Drink it frequently. It cleanses your body. Besides that, milk and malted soy drinks tend to be good as well. Not to say you can't have the odd soda every now and again, but not all the damn time like most people drink it. You know how people say you drink stuff like water when you drink it frequently, right? It's because you're supposed to be doing that with water.
Go out more. Get a bit of an active lifestyle going. I don't care how. Go for walks. Nature hikes. Bicycle routes. Jogging. Mug an old lady. Just go out and do things.
It might sound like a hassle, but it's going to power you up. After a while of this, you'll notice you'll feel more tired when you don't go for that quick dash or did the routine exercise in the morning.
Most importantly: shift into this gradually. Don't fucking jump into it in one go. You'll never be able to hold onto it and you'll find yourself demotivated before you know it. As much as your brain craves it and advertisers promote it, good lasting changes are never made instantly.
