Never got to the really big stage, peaked at 39yo 224lb, 5'10". 140lb with steel toe rubber boots and uniform when I was 19. My problem is being sedentary and lonely so I eat when bored.
My desire to get healthy is sparked by potential heart problems and poor self-esteem. I was "forced" into exercising when my car died - decided nothing was so far away I couldn't bike there instead. My only exercise is commuting/utility cycling and turning work or other daily activities (stairs vs escalator or elevator, etc) into exercise. Consistently hitting lower 190s now, and expect to break 190 this week.
Diet is better but till have bad days.
