You can do it. Last fall, my doctor told me I was fat. You can thank two years at Google followed by a year of falafel at the place across the street from Odeo for that. I was clocking in at 200lbs and things were not looking good. In October, Obvious acquired Odeo and Twitter and I joined a health club. Then things started picking up.
Part of my problem was that somehow I had convinced myself that living a vegan lifestyle had me covered. Not true. My doctor's advice was very straightforward "Eat less and exercise." So I joined a health club and followed his advice. It took five months for me to lose 30lbs and it was a blast watching them melt off. Now I work out just about every day and I watch what I eat.
