<human>: I've lurked here a while and I just signed up for Operation:Spring Cleaning so I guess it's time to introduce myself.  

I'm male, 31 yrs old, 5'8", and I currently weigh 250.  I work as a staff writer for a nonprofit company, so I'm not as active as I used to be.  I've been around this weight now for roughly 3 years probably.  Before I started working in an office about 6 years ago, I fluctuated around 195-200 and didn't look that bad to be honest.  I'm pretty stocky to begin with.

But yeah, getting older, getting worried about my health and I want to be more attractive to my fiancee who has been with me before I gained all the weight. 

I've been doing the couch to 5k program for the last 3 weeks and I've lost ten pounds in the first 2 weeks but haven't noticed a change in weight after the last.  I can run now though, so that's something.  My diet isn't terrible,  I usually skip breakfast, exercise on my lunch, eat a tuna sandwich and then something for dinner, usually (unfortunately) it's something like Q-doba or Zaxbys.  We've fallen out of the habit of eating at home cuz of our work schedules.  

Anyways, that's me.  I look forward to any advice that can help and I can supply more info if people want.

Can you summarize the given text in a few sentences?
<bot>: I want to lose 50-70 lbs.  I walk/jog 3 days a week for nearly an hour and I eat fast food at night.  Woo!
