I am 18 years old and live in Minnesota.
I didn't realize I was getting paunchy until December of 2006, when someone so graciously pointed it out to me. I wouldn't say I was FAT, persay, just getting chunky. I was at a BMI of about 25.1, with a weight of 170 at 5'9". Not too bad, but I didn't look how I wanted to look, so I buckled down and went on a strict diet. I did lose weight a lot faster than I should of, not on purpose, it came off quick by itself.
I knew I was embarking on quite the rough road to change, so I decided to take all my stats before I started, weight wise and health wise.

Update: I've been lifting weights and am up 7 pounds of muscle, 3 pounds of fat. I'm aiming for another 8 pounds of muscle before I cut and lose some of the fat while continuing to lift weights to preserve my muscle.

Before as of January 1st of 2007...
Weight: 171
Resting BPM: 81
Blood Pressure:129/90
Body fat %: 19
BMI: 25.3

And then here's what we have now...
Weight: 145
Resting BPM: 50
Blood Pressure:111/73
Body fat %: 11
BMI: 22

It was a difficult road, but it was achieved through a reasonable diet and plenty of vigorous exercise daily.
