Gain weight during pre op liquid diet?

I started my liquid diet May 10. I have 4 protein drinks a day broth once or twice a day and water in between . I lost mental focus the first day and cheated and had a hotdog for dinner but have maintained mental focus since then and have had nothing else. Weighed 244.4 May 11 in surgeons office, just now weighed 255.2. What gives?????

    Its the carbs that cause the major issues. Im struggling with the pre op diet too... only thing getting me through is my surgery date is this Thursday. Be kind to yourself it is hard, but will be so w

  • You gained 10lbs in 3 days? Did you mean to type 245 instead of 255? It's probably just a difference in scales. I'm struggling on my pre-op diet too but as everyone says, just keep at it.

    Exactly, the weight at home on your scale is likely to be different from the weight on the doctor's scale. Basically, at home, I weigh myself naked first thing in the morning after using the wash

Basically, at home, I weigh myself naked first thing in the morning after using the washroom. This is so that I have a baseline: the weight of clothes and other such stuff doesn't interfere. This isn't some cheap scale that I found at Goodwill either, it's a Withings scale which syncs my weight to the cloud (which is actually kinda cool, because it allows me to graph it and see patterns and progress).

At the doctor's office, I would be genuinely surprised if I DIDN'T weigh differently. Different scale, I'm clothed and I've had at a bare minimum at least 1 litre of water. Of course, I wake up at 5:00 am every morning, so there is a difference in time as well.

I'm so sorry ... Fat fingers. Not 245, 254. Gained a pound

Um, if you meant 254, then per your original post, you gained roughly 10 pounds.

If you meant 245, then you gained a pound.

So, it's 245?

I weighed in Thursday at 254.4, today at home weighed 255.2.. Sorry this lack of food has me all messed up lol

Ah, gotcha. Sorry. ^_^;;

Anyway, are you sure there aren't low-sodium broths? Yeah, salt definitely aids in water retention.

I looked for low sodium and there's even a sodium free but it has 10 calories and sugar and carbs . I think I will buy some low sodium tomorrow. I've been increasing my water thinking that would flush it out but just making me feel like a bloated whale.

Maybe you should discuss it with your surgeon's office? They might have some ideas about what works and what doesn't. As for the sugar and carbs, everything has sugar and carbs in it. If you were losing weight during your medical weight loss classes you might be okay. I think the issue of why they have you on a liquid diet prior to surgery is because they don't want anything physical in the stomach when it comes time to slice and dice.

It's to reduce the liver. I was not required to lose any weight prior to surgery, but he does have to move the liver so they don't want it inflamed as many obese people have. I emailed my dietician though. Hope to hear tomorrow

I thought that sounded a little familiar, so I pulled out my paperwork I got from the patient education seminar and saw a slide that read this:

  • We expect weight loss prior to surgery
  • Even a few pounds (5-10) can make a difference - Liver
  • Do not gain weight
  • May cx (cancel) surgery if there is weight gain

... So yeah, I need to be extra mindful about that.

If you regularly menstruate, you may also be at a point in your cycle where you gain a little extra. On average, I gain 2 - 5 lbs in the 10 to 5 days before my period starts. It returns to normal the day my period comes. That could be a factor too!

Try a water pill....just one....and drink tons of water....it will get rid of the sodium water

The pre op diet is to shrink the liver so there is room to get to the stomach.


I didn't use low sodium broth, and I also ate jello (sugar free) and some clementines, and watermelon the first week.

Second week I did protein drink with fish and cabbage salad for dinner nightly. I drank 65-88 ounces of water a day.

Tonight I had a rather huge dinner, salad, pasta, bite of tuna and handfuls of low sodium chips, none of which was satisfying ( I developed a like for healthy foods )

Sunday and Monday it's just liquid. Tuesday is surgery.

I dropped 20 pounds total. My weight fluctuated up and down 2-3 pounds depending but then would drop by two pounds at a time.

I started the diet on the 1st. Lost the most weight second week, and this week.

Pre-op wasn't required but I decided to anyway. My Doctor is very pleased.

By the way a pre-op doesn't shrink the liver but removes the slick fatty coat on the outside of it, this was told to me by another friend's whose doctor is also a liver specialist. Removing the slimy fatty film makes it easier for the tools to handle it and move it out of the way.

My doctor said that they don't know how diseased a liver is, or how big or small the liver is as a result of that disease until they open us up, the pre-op diet makes no difference, hence why no pre-op diet.

But he also said that people who start a pre-op generally do better with their weight loss.

I did to be safe, get a head start, and see what's in store.
