I cheated on pre-op diet



Recommended Posts

Ok, so I was suppose to do a pre-op diet consisting of low carbs w/ only 700-900 calories a day for two weeks prior to my vsg surgery. To say the least I cheated 3 days and now I'm scared my liver hasn't shrunk enough although I have been losing 1-2 lbs a day. I still have 5 more days until surgery which plan on doing a strict liquid diet of Protein Shakes and Water. Will this help?

So....14 Days total

6 days you did ok

3 days you cheated

5 days to go.

I think as long as you don't cheat any more at all...and do your last five days by the book...my gut says you'll be ok. (as always, asking your group is the right answer here)

The main downside to cheating is that when you do you're reseting the clock so to speak. The pre-op diet is meant to be low carb and get your body into a state of ketosis. If you introduce carbs back into your diet then you're stopping that process. It may take 2-7 days to enter back into that state. Mind you everyone is different.

That being said I wouldn't worry that much, but stay strong the final few days. Keep that in mind that the better you do for just a few more days the better it sets you up in the long run for the other side. It's tough but you can do it!

From what I have read and seen (youtube videos) people "cheat" all the time. Do what you need to do to get and stay on track. Stay strong. Mind over matter girl, trust me!

Huh, I've never heard that part about ketosis. I thought the purpose was calorie restriction to induce visceral fat loss around the liver.

I know you can maintain ketosis long-term on up to 50g of carbs but usually it's recommended to stay under 20g to induce it for the first time. Many Protein Shakes and bars contain sufficient carbs to total more than 20g, right? My diet in particular is 5 shakes OR 4 shakes, 1 bar OR 3 shakes, 2 bars. I could stay at 25g carbs if I did all five servings from Premier Protein shakes. But if I added, for example, just one Pure Protein Bar, that's 15-25g just right there, plus 20g for the 4 shakes.

It's been several years since I was interested in Keto so maybe the recommendations or guidelines have changed.

Lol that's when I have cheated as well. It seems like I'm fine during the day but at night time is when I cave in. My surgery is Thursday.

I was told that if you don't eat enough during the day you will be hungry at night thus making you vulnerable. So I made sure I started my Protein early and every 3 hours. It worked. But that was only for a week.

      I am new here today... and only two weeks out from my sleeve surgery on the 23rd. I am amazed I have kept my calories down to 467 today so far... that leaves me almost 750 left for dinner and maybe a snack. This is going to be tough for two weeks... but I have to believe I can do it!

      Hey everyone. I'm new here so I thought I should introduce myself. I am 53y/o and am scheduled for Gastric Bypass on June 25th, 2025. I'm located in San Antonio, Texas. I will be having my surgery in Tiajuana Mexico. I've wanted this for years, but I always had insurance where bariatric procedures were excluded. Finally I am able to afford to pay out of pocket.  I can't wait to get started, and I hope I'm prepared for the initial period of "hell". I know what I have signed up for, but I'm sure the good to come will out way the temporary period of discomfort and feelings of regret. I'd love to find people to talk to who have been through the same procedure or experience before. So I look forward to meeting you all. Hope you have a great week!

      On day 4 of the 2 week liquid pre-op diet. Surgery scheduled for June 11th.
      Soooo I am coming to a realization
      of something and I'm not sure what to do about it. For years the only thing I've enjoyed is eating. We rarely do anything or go anywhere and if we do it always includes food. Family comes over? Big family dinner! Go camping? Food! Take a short ride or trip? Food! Holiday? Food! Go out of town for a Dr appointment? Food! When we go to a new town we don't look for any attractions, we look for restaurants we haven't been to. Heck, I look forward to getting off work because that means it's almost supper time. Now that I'm drinking these pre-op shakes for breakfast, lunch, and supper I have nothing to look forward to.  And once I have surgery on June 11th it'll be more of the same shakes. Even after pureed stage, soft food stage, and finally regular food stage, it's going to be a drastic change for the rest of my life. I'm giving up the one thing that really brings me joy. Eating. How do you cope with that? What do you do to fill that void? Wow. Now I'm sad.

        I hope your surgery on Wednesday goes well. You will be able to do all sorts of new things as you find your new normal after surgery. I don't know this from experience yet, but I am seeing a lot of positive things from people who have had it done. Best of luck!

        Life as a big person had limited my life to what I knew I could manage to do each day. That was eat. I hadn't anything else to look forward to. So my eating choices were the best I could dream up. I planned the cooking in managable lots in my head and filled my day with and around it.

        Now I have a whole new big, bigger, biggest, best days ever. I am out there with those skinny people doing stuff i could never have dreamt of. Food is now an after thought. It doesn't consume my day. I still enjoy the good home cooked food but I eat smaller portions. I leave food on my plate when I am full. I can no longer hear my mother's voice saying eat it all up, ther are starving children in Africa who would want that!

        I still cook for family feasts, I love cooking. I still do holidays but I have changed from the All inclusive drinking and eating everything everyday kind to Self catering accommodation. This gives me the choice of cooking or eating out as I choose. I rarely drink anymore as I usually travel alone now and I feel I need to keep aware of my surroundings.

        I don't know at what point my life expanded, was it when I lost 100 pounds? Was it when I left my walking stick at home ? Was it when I said yes to an outing instead of finding an excuse to stay home ? i look back at my last five years and wonder how loosing weight has made such a difference. Be ready to amaze yourself.

        BTW, the liquid diet sucks, one more day and you are over the worst. You can do it.
