Hello,
I lost 20 pounds a couple of months prior to my surgery, starting out at 334 pounds... my highest weight ever.
Since my surgery, which was about 6-1/2 months ago, I have lost an additional 84 pounds. I still have about 65 pounds to go before I get to my "goal" weight.
My weight loss pattern has been much like blizair's as he stated above. I usually lose about 3 pounds a week for a few weeks, then maybe a pound a week for a couple of weeks... then back to losing 3 or so pounds a week. That has pretty much been my pattern for the past few months. During the first two months, the weight came off a little faster. I am in no way discouraged or frustrated when I have those weeks where I only lose a pound. I also hit a couple of stalls a few months back, where I went a couple of weeks without losing any weight. I didn't let that bother me one bit. Stalls are going to happen.
I am encouraged by all of the weight loss, and the way my clothes/sizes have changed. I've gone from a 4-5X shirt to an XL (14-16), I've gone from a size 30 pants to a size 18. I am thrilled.
Blizair is right, follow your plan, work hard at it, and you will be successful!
I have only one regret, that I didn't have the surgery sooner!
p.s. Good luck with your surgery tomorrow and best wishes for a speedy recovery.
