I joined this forum back in December of 2005. I weighed 305 lbs at 5' 8". I have several friends that are strong riders and were encouraging me to ride with them so I bought a bike (predictably too much of a bike for my needs), and rode with them a few times but could never stick with it, despite a few failed attempts to get into cycling over past few years.
In May of 2008, I weighed 310 lbs (my all time high), and found out from my Doctor that in addition to all my other early mortality warning signs, I had now developed type 2 diabetes. I don't know why it took that particular piece of bad news to motivate me, but thankfully it did. I jumped on the elliptical trainer at the gym that night (May 10, 2008) and haven't skipped a day since! I cleaned up my eating habits, did a bunch of other lifestyle improvements and last Sunday (November 16, 2008) I weighed in at 199 lbs! That's 110 lbs in 190 days (just over 6 months). Along the way, I've pretty much reversed every major health concern I had.
I still have a bit to go (my healthy weight is probably around 180 lbs), but I'm confident I'll get there. And I need to make sure I maintain an active lifestyle that doesn't let me fall back to my former state.
Of course just as I get the bug to start riding, it's getting pretty cold here in Portland, Oregon. I did take my first spinning class last night and it felt great. At the very least I hope to set up my trainer and put in some indoor miles this winter. By the Spring, I'll be at my ideal weight, have some base miles on my legs, and be able to really enjoy this great sport.
I hope I'll still qualify as an emeritus member, even though I didn't lose most of the weight on my bike. This forum has always felt like my home base for the cycling community.
