I’m almost at the end of my 2nd week of my pre-op diet. I started 12 days ago and weighed 333. After the first week, I was down 316. The last 5 days, I’ve gained 2 pounds. I don’t understand why this is happening. I’ve been very strict with it (no cheats) the last 5 days. All told, I’m only getting between 600-700 calories per day, and I’m averaging close to 10,000 steps per day. What am I doing wrong? How is this possible? Am I just retaining water? Has anyone else experienced this before?

Thanks for any ideas you may have.

Unfortunately the body isn't a machine, many other factors to be considered when it comes to weight loss even when on low calories. You won't lose weight all the time and sometimes there are gains.

At a guess, its likely hormonal or body taking time to adjust hydration levels. A lot of the inital weight loss was likely fluid and your body became dehyrdated. When the body dehydrates it hangs on to the fluid for a while. If the weather is hot you could also be retaining fluid because of that.

Keep going you are doing well, won't be long before your surgery, hope it all goes well for you.

Don't stress about preop weight loss it's just a liver cleanse..
