Ask Lemmy

If taste isn't a concern, I've gotten by with chlorella and cocoa chia pudding for longer than I care to admit. I don't mind the taste of chlorella, but most people apparently don't find it and other seaweed all that appetizing, but it's a drink so you can just chug it like a beer or something and neutralize the taste with like a splash of lemon juice or water with lemon juice. Won't fill your stomach all that much, though.

Miso soup (with wakame and maybe tofu and veggies cut down to tiny pieces?) is also a great addition to that.

Bananas. Easy to eat, nutritious, and even helping if you happen to have digestive issues. Very stable food, it's my go to when nothing else goes.

Another great option is diluting a stock cube (or half) in hot water and drinks it as a soup. Nutrients, vitamins and minerals! Very good for rehydration

Toast, banana, sunflower seeds. Those are my too sick to eat go-tos.

i have no idea but try wafer rolls

I like otter pops when I have a sore throat!

Buttered toast with salt, grapes (possibly frozen), Gatorade.

Any form of crackers works for me. Cheese flavored are the best for me, but just about any form of crackers or food that is well baked.

Fasting can actually help recovery. But no matter if you eat what you can or nothing at all it is absolutely necessary to get enough water, salt, and potassium.

Something that might go down easy is plain canned beans, just make sure to drain and rinse them and maybe even soak them a little to minimize intestinal issues. Plain quinoa or lentils made in a rice cooker or pot with just water and salt could also be good.

Sometimes your hear about the BRAT diet. I'd recommend against it, it is very nutritionally poor so it will not give you much energy if you can only handle eating a little.

bacteria might help

to eat something to keep my strength up

I wouldn't worry too much if you haven't eaten for a few days. I know of one instance where someone who was seriously obese went on a diet, and aside from vitamins and water, went over a year without eating. I've done over a week myself for the hell of it. Unless you're absolutely emaciated or have some sort of medical condition that creates a need for it, you can probably handle going for quite a while without food.

All that being said, this isn't to encourage doing it. Just that you're probably not creating any kind of dire health situation if you don't eat for a while.
