Ah, it's okay. It's not that hard to get back in shape at all, as long as you do some of these things. You just need to stick with it. ^_^; Kairyu and the others gave some useful advice, but I'll still give some of my own health tips.
Drink lots of water and juice. Especially pineapple, apple, grape, etc. And every morning when you wake up, make drinking a glass of water one of the first things that you do. In fact, I would recommend cutting out soda and any other kind of junk, or atleast minimizing your intake. Soda has nothing in it that is good for you, so there's no use drinking it. And stay away from diet drinks. They have a chemical (Or something) called Aspartame in them, which is bad. (It subsitutes something in the regular drinks, but it's not good.)
Eating a lot of food all at once is no good. It's okay if you get hungry easily, just stay active during the day and you'll have no problem. It's better to eat small amounts of food at different times of the day instead of large amounts three times a day.
Stay active. This is most important for getting and staying in shape, plus it's extremely good for you. Don't just sit around all day, or else all of that wasted time will come back to haunt you when you're older and you find out that you have some kind of disease. When you stay active it keeps your blood flowing. When you don't, it just goes slower and your veins (I think) can get clogged up, and if they do it's deadly. Even if you don't have enough time to work out two or more hours a day, just 30 minutes atleast 3 times a week will keep you healthy. Whenever you have the chance, go on a walk, go swimming, get involved in sports, play outside, etc. There are a lot of fun things that you can do, and you'll hardly realize that you're actually excercising. Just don't push yourself. Go at your own pace. Don't expect to just be able to run 10 miles on your first try. You have to build up your muscles, and eventually they'll be really strong so maybe you could do that. Excercising isn't only for losing weight. It's good for you. A lot of people that are in shape excercise just because they want to stay healthy, and live longer lives. I know this for a fact. My 67 year old grandmother excercises every day, and she can do some things that I can't, or can
barely do! O_O She can raise her whole leg up to touch her head. Lol, that's some proof. Also, if you just walk really slowly you're not going to get anywhere. Go up hills, walk fast, etc. And stretching before you walk or do any kind of excercise is a must. Always do that.
And if you want to try it, here's a really good diet that works. I know, it seems like it would be hard, but it's only three days, and if you stick with it and follow it exactly, you could lose a lot of weight very easily.
