So, I'm curious what you all lost on the preop liquid diet (I'm doing 10 days starting next week) and in the first 2 weeks post op. Partially pure curiosity and partially because I'm supposed to get fitted for new uniforms at work tomorrow and I'm wondering if I should just tell them to make a size smaller than I am now. I wont be into the new ones until after I come back from surgery. Surgery should be 9th (tentative), returning to work the 26th.

It varies so drastically, I don't think there is any possible way for you to predict. Plus, even with a massive loss, you may not go down any clothing sizes. I think I had to lose like 40 pounds before I went down even one pants size.

I lost 11 pounds on my pre-op diet (15 days) and 14 pounds in my first month post-op. Some people lose like 20+ pounds on pre-op, some people only lose 4. Also, keep in mind that not all pre-op diets are created equal. Mine was very strict and only totaled up to 450 calories a day. Some people eat more like 1200 calories a day, depending on their guidelines.

​Like @@JamieLogical, I didn't go down in clothing size until I hit around 35 pounds lost. My pre op diet was strict as well with a long two weeks of liquids afterwards. Pre op I lost 13 pounds and only about 7 pounds the first two weeks post op. It's hard to know what to say about your uniform. Good luck on your life changing journey!

I lost 37lb pre-op

My surgery is tomorrow and I've lost about 10 lbs on my 10 day pre-op.

Thank you all for your responses. I knew it would vary but was just curious to hear what people lost at the begining. Getting so excited and worried now that its only a couple weeks away!

I only lost four pounds on my two week liquid pre op diet, but post op my weight came off much quicker.

If I was you I would order one size smaller in the uniforms. I wear uniforms in my job too. I ordered one size smaller and then as I lost weight I would get them altered and then reorder as the altered uniforms got too big.

Good luck

I lost 20 lbs in a two week pre-op at 1000 calories, and that included some serious cheating as well, so adjust upward by as much as 500 calories. I did a lot of exercise to compensate, as I just couldn't stick with 1000 (I can do it with the sleeve just fine). I also found going to liquids the last three days before very helpful.

First two weeks post-op was roughly another 15 lbs. However, as @@JamieLogical said, that may not equal a size, as much of the weight is water and glycogen storage in your liver. After that, size will follow weight loss a little more closely.
