I have got all of you beat.
When I was 18, I was lifting and running everyday. 5'9" and weighed 220 pounds. I ran 2.5 miles in 20 minutes. I had a 36 inch waist.
Fast forward 14 years through college, desk job (I was a coder for an oil company), marriage, knee problems (unrelated to weight) and kids and I was sitting at 276. I had a 44 inch waist. Needless to say, I did not have a height growth spurt
My wife and I said "fuck this!" and got our asses in gear. She has gone down 3 dress sizes. I couldn't be more proud of her. She works out after work and if she has a late meeting, she wakes up at 4:30 to get it done.
I have lost 6 inches off my waist and 36 pounds. I just recently ran 1.5 miles for the first time since high school.
I will never, EVER be that big again.
