How is it going OP? You better not post that you have quit or made no progress!
A lot of good information in this thread, our bodies are amazing and they can work themselves out....I know guys who are the size of bodybuilders who don't go to the gym, all they have is a pull up bar and a weight set...You can do it all in your home, don't think otherwise...I live on a 2nd floor apartment and choose to go to the gym to do my jump training, and cardio, but do everything else here...
I would just like to add: Do what works for you...P90X might work for you, Insanity might work for you, simple circuit training might work, or maybe just a long jog/run works....just get out there and get active...I am a computer guy so I am in the same inactivity boat, its rough!
Heres what works for me (and I am still fat!):
P90X + 1 hr of cardio 3 days a week, and an Insanity workout when bored.
I do take supplements: Animal pak vitamins, Isopure protein, creatine, L-glutamine, and jac3d before cardio sometimes.
Every time you mess up your diet - put money in a jar and give it to someone...
Simple diet, low carbs, high protein - 8 - 200 cal meals a day...
On cardio days I eat more carbs an hour or two before my workouts.
My best investment in 2010 was a George foreman grill, no joke.
PS: weight yourself 2 times a day, you will see fluctation because of water weight and stuff, but its a mental push...track your diet with

Now:
fairly simple, dont eat a lot and burn what you got off...
Realize you need to do different programs/diets to achieve different results.
Don't just take something off the web and use it as your own, your body is unique.
Figure out what it needs...don't get hooked on thermogenics!
I like P90X because I can go onto youtube and twitter and have a support group, watch other people struggle and get pushed myself...I'm now starting an out of home program called crossfit...It's insane!
Good luck, give is an update.
