I’ve had my gallbladder removed and to be blunt, you will know if it is an issue. (Here is the blunt and a bit gross part) After surgery some people can respond poorly to fat in that they get constant “dumping syndrome” or aggressive diarrhea. This can last for a few weeks, months or years. I am 10 years out and I still have issues. I am on DIY because I still can’t tolerate as much fat as regular Soylent has. The best way to know is to try it. If your healthcare professional has said that it is ok to continue the soylent then I say test it out. If you have no adverse reaction then great.
Something to note. It was never an issue of daily fat intake for me. It has always been an issue of how much per meal. So if you find yourself having trouble then perhaps cut down to 4 a day but add low fat milk to each serving and drink it a bit slower. Adding a bit of fiber to the soylent might help too.
I have struggled for years to find a proper balance. Fortunately, my DIY has done wonders. I used to take calcium citrate supplements before they started to give me headaches. The calcium would bind to the bile and help bulk things a bit. My issue was that, without a gallbladder, I had a steady bit of bile constantly dumping into my stomach so if I went for a long period without eating my digestive track was gunked up with bile in between meals. That caused for me to have urgent bathroom moment. Eating small amounts throughout the day helped. I currently eat my DIY 5-6 times a day in smaller amounts.
Another thing I had heard of whs people supplementing with ox bile when they eat. Without a gallbladder some don’t have enough bile to digest larger meals properly. I have tried it but didn’t notice a difference.
Of course, your health care provider will know best what to do but this was my experience. Be mindful of what is working for you and against you. Fat won’t necessarily kill you but you can have a really bad time. That is why they recommend restricting it. Be prepared to need the bathroom after each meal. I didn’t have soylent but I am curious if it is a blessing or a curse after because I had a rotten time before I learned to balance things a bit. It would have been awesome to have something so convenient during recovery. The pain after isn’t that bad but it is a bit tiring.
Good luck and let me know how the soylent works for you!
