Weight loss and perseverance

The heaviest I have ever been is 233 lb
I'm about 5'10 now, at one point I was 6' even. My Dr (actually I usually see the PA) was complaining about me losing some, last time in I was down to 214.
I used to work with a guy who was ~5'8 and at least 500#. He lived at the bar, and while at work always did the minimum. This was a guy that you never wanted to be downwind of, without a gas mask....
I often told my wife that if I got anywhere near that size, to fix it the easiest way, just feed me some lead....
