Doctor said 200lbs to 220lbs after surgery

Who knows how low your weight will go ..... Just work your program and see where you get.

Dont focus so much on numbers, try to focus on health.

I can't think of a reason not to work out during your pre op diet.  

It's tough to say without knowing how tall you are. I had RnY and was told that I would lose 50 - 80% of my "excess" weight. They calculated excess weight based on a BMI of 20. I started at 337, and am at 197 now (I'm 5'11"). I would like to get to a BMI of 24.5, and although I am losing really slowely, I think I can get there by my surgiversay. 

I think you can do it. I'm 6'3", high weight was 475, surgery weght 359. My surgeon's goal was 250, my own goal was 225. I've been within 3 pounds of 185 for almost a year and a half.

You can do it if you put the work in.

thanks!  Man thats really good 

"On average, people lose 61% of their extra weight after gastric bypass surgery."  Take me, for example.  I weighed 320 pounds when I started.  I "should" weigh 145.  So that's a difference of 175 pounds.  175 is my "extra weight."  61% of that is about 106 pounds, which would put my finishing weight at:  320-106 = 214 pounds.  My actual weight at the moment is 180, so I'm calling it a definite WIN!  (And I am 7 years out)  I would ask your surgeon about working out during the liquid diet.  I didn't have to do that with my surgeon, thank God! 

I think it's very realistic but the time frame is totally up to your own body. You and have have the same starting weight and, at 3 months post-op and including my 4 week liquid diet, I'm down 85 lbs.
You'll have to see how you feel on the liquid diet to see if you can handle working out. I did cardio a few times a week and  core work nearly every night during the pre-op diet (I wanted to be as healthy as I could be going in). I was pretty bagged by the end of the day and I have a sedentary job, a small condo, and no yard work, so my energy expenditure was pretty low on a daily basis. I don't think I would have had the energy for weights or anything much more than what I was doing.

I think Im going to just do cardio....i actuall like it better than weights surprisingly
