For anyone else looking to shed some pounds here is my advice, I am no weight lose guru nor do I suggest you start by choosing one. Unless you are a very driven person you will fail in your dieting goals mainly because you are setting unrealistic goals. You will NOT lose 30lbs in a month. You should be happy to lose 4lbs in a month. I already know what you are saying "4lbs a month, then why should I even bother?" Because you dolt 12 months of that and you will have lost 50lbs.
Start with minor changes because major ones will just make you want to quit that much sooner. Trust me going out and getting a gym membership and starting a new diet tomorrow is setting yourself up for failure for most people. First you can lie to everyone else but if you are going to lie to yourself be consistent. If you are going to round up how long you excercised then you MUST round up how many calories you ate.
Ok you have decided to take the first step. For the first few days do nothing different in regards to your diet and excercise but observe it. Pick a day or two and add up all the calories you are eating and don't subtract anything for excercising. Take three pictures of yourself front, back, and the dreaded side. Step on the scale and record your weight. Put those pictures, the calorie number, and the scale in a safe place for a month and ignore them.
The next thing to do is start making small changes and setting small goals. None of the goals should be in regards to the amount of weight you wish to lose.
1) Throw out all "high level" junk food ie candy, ice cream, chocolate and replace those with "medium" or "low" junk food ie pretzels, crackers, etc. Don't try to make the jump to fruits and vegetable snacks to start off, remember small changes small goals.
2) You must start some sort of cardio excercise. Jog, treadmill, do a video, or whatever for 5-10 minutes. Stop when you start to get too frustrated but try to do whatever it is to take your mind off of it, listen to music, read, I play xbox.
3) Try to do crunches and push-ups.
4) Your goals during this period should be to increase you excercise period or intensity and decrease your portions. Try to increase your excercise time by 10-30secs each time or if you went .5 miles last time in 10 mins go further in 10 mins. You can still eat the same foods just try to reduce their portions.
5) Don't think about fat content etc think about it right now as addition and subtraction. You were eating X calories but now you are eating X calories - junk calories - portion difference - excercise.
6) Try to excercise everyday... remember its starting at 10 mins
After a month pull out your pictures and numbers. Take and record new ones. If you didn't lie to yourself you should see postive results. Put these away again for a month. Now start to make more small changes to your diet where you can. Remember to think of it as addition and subtraction. Eat a candy bar one day and then try to burn those 200 calories off, I promise you will stop eating candy bars after RUNNING for an hour

Keep increasing your cardio and get serious with the crunches and push-ups.
After the second month you can start thinking about a gym membership and making more dietary changes.
You aren't going to see huge changes immediately but if you didn't lie to yourself and started excercising just 10mins a day at the begining then you are hopefully doing 30-60 mins now and its easy because you didnt start out with that huge change. Eating a lot less junk food is probably easier when you start to realize to subtract what you just ate you would have to run for 10 times longer than if you just ate that carrot.
Speaking of carrots... try to find a reward at the end to hold your focus. Maybe its a reunion, maybe its a wedding, maybe it is a vacation in a bathing suit, or a new tattoo on your chiseled body

Everytime you start to slip think about how you will feel in that bathing suit or how your high school crush will look at you when you do succeed vs if you dont.
Good luck
