Just get a check on it people and realise how remarkable creatures mushrooms are. You’ll see that different strains have different nutritional values, and of course they contain trehalose, kind of a mushroom sugar, so carbos are no problem. Usually mushrooms are considered to be thermogenic so you would starve yourself to death on only mushroom diet but with meat on the plate and a rotated mushroom species on side probably most of us would be healthier than now. See also if you irradiate mushrooms with UV light (can be done with a bulb) it will drastically boost Vitamin D content so even taking a nuclear sunbath isn’t necessary.
Tho reading some comments I recommend people to check upon trusted sources or there will be a lot more casualties upon a go-live-underground scenario.
OK, so the pigs eat other pigs and mushrooms. But what do the mushrooms eat? You could stockpile media for growing mushrooms but eventually that will be exhausted if you are trapped forever deep underground. There is no such thing as a free lunch.
Rabbit meat is ultra low fat and can cause serious health issues because of the lack of dietary fat if you subsist mainly on vegetables like Jerusalem Artichokes and cattail roots [common emergency winter survival foods if you are stuck somewhere like the Adirondacks or equivalent. I did a winter survival course there when I was a teen] with easily killed bunny. You should expand your diet to include fowl - water fowl like duck or goose is excellent, pheasant is also good or a fatty fish like salmon works as well.
Many mushrooms will happily grow on shit, so compost up the shit, cooking scraps and trash and any other organics that will break down.
That is true, Snowshoe hare and some other rabbits are too lean to subsist upon in cold climates, where you need extra fat in your diet.
But that doesnt mean meat, as a whole, including fowl and fish, do not generally have plenty of needed fats.
But where do you get the shit? From the pigs and humans, right? And how did they produce it? From eating pigs and mushrooms.
The second law of thermodynamics will catch up with you eventually.

Different people have different nutritional needs. For instance, some people have problems absorbing vitamin B12, or non-heme iron, or converting beta-carotene into vitamin A, and so forth. So I suspect this diet would create immediate selective pressure on humans.
The proposed diet is deficient in vitamin C. I heard about a guy who tried to live on a meat-only diet and suffered from scurvy. Mushrooms aren’t exactly a good source of vitamin C either. For that matter, I suspect pigs could not survive too long on just mushrooms. And of course there’s the lack of carbs (one of the three main dietarypillars). Human ancestors lived off of fruit and meat (carbs from one, protein and fat from the other) so the movement to eliminate carbs sounds like nonsense to me.
Yeah, this scenario makes absolutely no sense, unless for some reason you can also grow some sort of plant that pigs can eat and humans can’t. (Acorns maybe? But I think people can eat acorns if you process them correctly, and if so, it would surely be more efficient to eat them ourselves than to use them to produce pork.)
Not only can you, some species of oak produce acorns that need little to no processing.
Some raw meats do have some vit C.
However, sufficient amounts of vitamin C can be acquired from raw liver, fish roe and eggs. Lower amounts are also present in raw meat and fish (1).
You can even live on meat and mushrooms, minus the mushrooms. The Anderson Family has been living on an all beef diet for the last 20 years. Just grocery store ribeyes and water, no salt, no seasonings, no supplements.
There’s an entire reddit community /r/zerocarb where there’s tons of people demonstrating that you can live successfully on an all meat diet.
I’m not saying it’s a great idea, reddit is a hub for all sorts of extreme diet fans. I’m just saying if you’re looking for existence proofs that it’s possible, it’s not hard to find.
