Question: I'm going to try to form a...

Start slow, switch your chips and cookies for carrot sticks and fruit, and then work your way up to super healthy meals.
For exercising, put together a simple 15 minute routine you can do at home. Push ups, jumping jacks, skipping rope, sit ups, weights, stuff like that. If you're up for it you could even got for a walk or jog. Also try joining an aerobics or self defense class. They will help build muscle and keep you in shape, also going to every class helps you keep on top of exercising.

I think the important thing in staying with it is routine. If you get used to doing it every day it'll start feeling normal after a while.
Good luck :)

Good for you! *approves*
Self-control and motivation tips...
Really just find out what works for you. When are you motivated? WHen are you not? Now make sure you always have that enviorment of motivation.

But these might help anyways :)
Eating right: I would say cravings and over eating would be the hardest part of eating right (for most ppl at least) so make sure you know how to control that. Distract yourself when your craving something or give in by just taking the tiniest nibble. Sit up strait when you eat (you don't feel as full when your slouching! No Joke!), be very aware of the serving sizes your are giving yourself etc.

Self control: I have no tips for this. For me, self control was something i simply had to give myself time to develop. But i know for some people setting goals and keeping accountable helps.

For me I do everything better when I'm doing it with someone else. Exercising staying on a diet, writing a paper, everything. So when I make a New Year's Resolution or something I always do it with someone or have a friend keeping me accountable.

Hope that mess of info helped some :P

Your P.E. teacher has a screw loose O_0 The abdominal muscles are smooth muscle; they will gain definition, but they aren't going to "grow outwards". Unless you're doing some hardcore muscle building training for competition, you aren't going to get scary-looking abs. If your stomach is hurting from doing sit-ups, it's because you've strained the muscles -- that's normal, and not something to worry about.

When you do too many sit ups too frequently your abs grow outwards, Thats what my p.e. teacher tells me when i tell her about the pain in my stomache from doing too many sit ups at dance, so think about that before yuu do.

I don't know if I have any really motivational, empowering things to say, but whatever motivation you find, make sure it's an intellectual motivation rather than an emotional one. Anyone can get worked up emotionally about wanting to do something -- but the people who stick with it are the people who surpass their emotional ebb and flow and find good, solid reasons to stick with it. Frequently, someone sees an inspirational speaker or video and vows to make a change, but they're only riding the high of the inspiration. They often don't follow through.

The self-control is diligence you build up for yourself. You can make it easier by setting alarms or reminders (Google Calendars can send text message reminders to your phone, if you think that will help), but after that, it's all about you: you have to self-moderate, you have to get up off the couch (or from your desk, or out of bed twenty minutes earlier than usual) and make yourself take care of business. If you believe you are worth the effort, you'll do it.

Either in the morning or the night before, make a list of what you want to accomplish the next day. Give yourself four things to do (a short set of exercises; cook a meal from scratch; take a walk; Drink 40 oz. of water over the course of the day); at the end of the day, evaluate whether you did them and keep a journal just to list what you did accomplish. (Forget whatever you didn't accomplish. Focus on the positives.) Until these become pretty solid habits, don't overload yourself with ideal behavior. You'll burn out really fast if you try that, and all your good intentions will be for nothing.

It takes twenty-one days to make a habit -- so, for twenty-one days, force your way out of bed in the morning to do however many reps of sit-ups you can do, run in place for however long you can, and stretch out. Stretching is very important! You'll be more flexible if you stay well hydrated and you do something to warm your muscles up first. Stretching is the single best thing you can do for yourself. If you do nothing else, STRETCH.

Don't force your eating habits to become perfect immediately. While it really is better for you to only eat things that don't require a nutrition label -- fresh fruits and vegetables, fresh meat -- you can still eat some junky stuff, as long as it isn't all you're eating. Once you're more in the habit (21 days!) of eating healthfully, you'll start noticing you have limits when it comes to junk food. (There's a goal to aim for: the point where junk food is only appealing in small doses!)

if you have control over it, make sure you only have healthy things to eat in the house, or as much as possible. that way you don't really have a choice. remember healthy by no means means bland or bad; a lot of yummy things are healthy. if you don't already and are able to, cooking for yourself really helps 'cause you know what's going into the food you eat. also, carrying around a snack is good and helps you avoid buying possibly not-so-healthy food if you're feeling a bit peckish on the go. this also saves you money. i've found that keeping a food diary really helps me, because then not only can i see and asses what i'm eating and how to change that, i also avoid eating unhealthy stuff because i don't want to write it down and admit to myself that i've eaten so much of it lol. as for exercise, i'm having trouble sticking to exercising everyday too, though i'm trying to keep my goals in mind and think about how good i feel after exercising. i'm taking a kendo class right now, which kind of helps me keep on track, so maybe try signing up for a class if you're interested. or if you have a friend who's also trying to eat healthier and exercise, you guys can support and motivate each other?
good luck, and hope this helps
