The thing that really got me was I didn't change my eating habits. I went from a job walking 5-6 miles a day, luggin a 300lb spray hose around to treat trees and shrubs, to being a sedentary office worker. I'm still active after work with playing and umpiring sports, but my calorie intake vs. output is way off. I actually just started running again, hoping that will get me back to my target weight of 190 shortly.
