Protein I think would be the issue. There was a case study on a morbidly obese guy that did this with doctors. What I remember is he basically told his doctor he was going to stop eating entirely. They could either help him and give him medical advice along the way, or try to just advise against and he was going to do it anyways. He would take a daily vitamin for general vitamins and I believe some yeast paste to give him protein. I think the dude lost like 400lbs in a year. Had small bowel movements every 30 to 40 days.
Edit: Apparently it wasn’t protein but amino acids.
he consumed only vitamins, electrolytes, an unspecified amount of yeast (a source of all essential amino acids)
I’ve never heard the yeast paste for protein part of this story before. Every time I’ve seen it repeated it was just salt and minerals he was supplemented.
I think you would be fine for a long time if you drank old-style beer. Unfiltered, low alcohol content, some remaining sugar/starch and with lots of yeast, maybe some impurities that probably contain amino acids, vitamin b12 and other important stuff.
Depending on how broadly we define beer here, you could totally end up with one with a surprisingly high protein content. Certainly not enough to live forever on, but I’d bet you could get a lot further than you’d initially think. People can go a long time on just bread, don’t see why liquid bread would be much different

Bottle conditioned would likely make a huge difference.
