Someone say healthy meals?
Make everything you eat yourself from fresh stuff you buy in the produce section. There are literally thousands of places online where you can get recipes ranging from simple and healthy to delicious and healthy. I mean... I used to work in a produce section. People walk in and out of Health Capital every day and they don't even realize it. It feels like worlds away from the hermetically-sealed packets of sludge sold everywhere else in the store.
Peppers, bell peppers, carrots, onions, beans, basically anything that doesn't come in a packet, bottle or tin is great. Live somewhere fairly rural? Farm stands have the best stuff, I find.
Go wild. So long as it's fresh produce and you're not eating too much of it, you'll be fine as far as nutrition goes. As others have said, it'll take a while for you to get used to it because all the crap you normally eat numbs your taste buds. That's not to say it can't be yummy, you can find all sorts of ways to spruce up whatever you're eating, tastewise.
Assuming that you live in America, it's getting to be fall, and fall in the US is squash season. Squashes are awesome. Go make stuff with squashes. Also in fall is apple cider. Apple cider is way better than the concentrated stuff.
If you're gonna make something with potatoes, go with sweet potatoes instead. Normal potatoes are pure starch. Sweet potatoes at least have some other stuff besides, like atrociously good amounts of vitamin A, calcium, magnesium and manganese.
Meats I would keep to chicken and fish. Avoid red meat. Red meats have absurd amounts of salt, sat fats and just grease in general. Nice on occasion, good if you're in a famine, but long-term, health issues abound.
Stop drinking sodas. There are flow-charts that shows the panic mode your body goes into when it drinks 8oz of coke. It's pretty gruesome. Drink water. Tap water is fine. Juice is also good depending on what's been done to it and how much you drink. Excess sugar just gets metabolized into fat unless you burn it straight off.
On that note, keep your meals varied and portioned reasonably. Everything in moderation.
On top of everything, supplement your meals with plenty of exercise. Some people recommend weightlifting, some recommend pull-ups, etc, some recommend martial arts. I'm gonna suggest running. Grab a pair of shoes with thin soles, go outside and run. Not on a treadmill, not in a gym, go outside in the fresh air and run. You can easily run a mile right off the bat, right now, right after reading this sentence if you pace yourself correctly and run with good form (mid/front strike. Don't run on your heels). Humans are natural runners, everything about the human body is designed for long-distance running, from your cardio system to your sweat glands to your Achilles' tendons. It's fun, it gets you outdoors and most of all, it's free. You'll be happier for it as well. And the longer you run, the more stamina and endurance you'll gain.
A bit general, I know, but hope it helps!
