I lost 215 lbs. in 15 months. My surgery was 10/24/07 and I hit the 200 lbs. lost at exactly 1 year out. I am 5'9".
I think you are doing great!! For comparison purposes, I lost 131 lbs by six months out, which meant it took me another six months to lose 69 more lbs. to achieve my 200 lbs. goal by one year out.
Since my 1 year surgiversary, I have lost 15 more lbs. , bringing my total to 215 lbs. by 12/24/08.
I'd like to lose 5 more to reach a final goal 150 lbs., but I'm not pushing too hard. I have loosened up my eating somewhat, and haven't lost a pound since Christmas Eve. I even gained 4 lbs., which I have since lost and am back to 155.
I have to confess that I have lost all this weight with VERY little exercise. I am not proud of this fact and have made a commitment that 2009 will be my year to get fit (2008 was my year to get healthy and I did it!!!!).
If you are wiser than I am and exercise regularly while keeping true to your nutrition guidelines, I feel very confident that you will reach your goal by your wedding day. Having said this, whatever weight loss you accomplish by your 1 year surgiversary (and wedding day) will be a TREMENDOUS achievement and one to be proud of.
Congratulations on your wonderful success and good luck with the remainder! Feel free to PM me with any questions.
