Don't worry, kid. I was the exact same way 25 years ago or so. That will all change for you in about 10 to 15 years or so...   Better live it up now while you can.   
  
Just for the record, I didn't see this thread when it first came up, so I didn't sign up for the contest. However, in the last six weeks, I've lost 7 pounds just by not eating to the point of feeling stuffed all the time (from 192 down to 185, and still dropping). Just this week, I got back into a belt (a 34) that I haven't been able to wear since around 9/11 - and the buckle is in the middle hole!!!!1 
  
I haven't done any more exercise/activity than before, haven't change what I eat, and I still have my "glass o' red" every night. It just goes to show, as Couloir and others pointed out a few pages back, it's simply a matter of "calories in / calories out." Get less in, you lose weight. Get less out, you gain weight. Simple math.
