I got to 220 lbs when I sat at a desk for 8 hours a day. I was always skinny as a rail as a kid and ate whatever I wanted. I stayed that way for about 10 years. I would hike some and bike, but it didn't do much for me until I started running and ate less carbs. I am 185 lbs now and have stayed around there for 6 years. I run 2 to 3 days a week about 3 miles at a time. I like a lot of the ideas from this web site, although I don't do everything he says. www.marksdailyapple.com/ alcohol is my one weakness.
