So, I am being sleeved this coming Monday, October the 10th! Very excited and can't believe it's almost here. I've been on the pre-op diet now for almost a week and a half and have lost a total of 2 pounds. Very confused by this. I am doing 2 shakes a day and one regular portioned low fat, low sugar, low carb meal. In between I can have snacks like sugarfree jello and pudding. I am down 31 pounds since I started going to my meetings the end of June and I'm very happy with this. However, I would have thought I would have lost even more weight in the last week and a half. I read on here of people loosing 10+ pounds on their pre-op diet and I want those results too. I'm tall and have a lot of weight to loose so I should be capable of dropping those large numbers. Praying for a big loss by Sunday night! Good news is I have not gained weight at all during the whole time so my surgery is still on. Just wanted to drop 9 more before I have surgery. Any suggestions?

I feel your pain. My surgery is the day after yours, but I had to follow a 4 week pre-op diet. Sounds like the exact same diet as you are following. I had the option of 2 shakes and 1 meal or 4 shakes and I did the 2 shakes/meal for the first 2 1/2 weeks and I've been doing the 4 shakes for the past week.I have lost slightly more than you, but not much. I lost 5 lbs the first week and another 4 pounds in the following 2 1/2 weeks. So a total of 9 lbs in 3 1/2 weeks. My doctor had not required me to lose any weight leading up to the surgery, other than this 4 week diet, so I'm sure the big drop the first week was the Water you lose like when starting any other diet.

Very very frustrating and it really worries me. I feel like I'm consuming less now than I will after the surgery, yet still not losing. So what's going to happen after surgery. Is it possible that I still won't lose weight? It's like my body won't get rid of this weight. It is a little concerning to say the least.

So I empathize with you, but lets hope the surgery will work and we just have to be patient.

Good luck on Monday!

I'm on day 14 of my pre-op diet (surgery is tomorrow). I found that on the days I didn't drink enough Water, my weight loss stalled. Just a suggestion, but make sure you are getting at least 48 oz of water in each day!

Good luck!

Losing 10 lb in two weeks is a tall order, particularly if you have already been losing some in the months before. Those who report losing that much are either doing so during a longer pre-op diet/exercise program that many docs and insurance companies require, or they had no significant prior weight loss effort so that their 2 week program loss was their initial loss.

It is not unusual to have a fairly large initial drop the first couple weeks of any kind of weight loss program. What happens is that most of the initial loss is from your limited stores of carbs and Protein, which lose at a rate of around 2000 calories per pound. After those first couple of weeks you will often experience a stall when your body realizes that something serious is going on starvationwise and works to adjust things before tapping your fat reserves, which then burn at a rate of around 3500 calories per pound, so your rate of loss slows some, but you are then burning mostly fat, which is the whole idea. You have likely already gotten into this fat burning mode from your efforts since June, so there really is nothing to worry about - things are going as they should.

Also, don't be surprised to see some weight gain when you get home from the hospital - they are going to keep you well hydrated with that nice IV bag feeding your arm. I think I gained about five pounds during that time, but it comes off quickly in a couple of days as you literally pee the weight away!

Good luck with it all - you already have a great start.

Just another suggestion is to make sure your cabs low, 30 - 40 grams per day, and your proteins are 70 grams or more. This will put you in ketosis which makes for faster weight lose.
