Assuming you need 2000 kcal a day: You'd need to cram all those calories into a pill, in a form the body can digest. Now, fats contain 9 calories per gram, so you need 222 grams of fat to get all those calories. You need proteins and carbohydrates and vitamins too, so you'd probably need to take 400 grams of pills every day, in the best case.

You could survive off of pills and water for weeks, sure. But you'd be starving the entire time.

Longer than that, you'd need proteins, carbs, fats, etc.

Best bet would be to also have some Ensure-style drink.

not really. yeah you get all your vitamins and minerals in pill form, but you only need micro-grams of those so its easier.

But if you try to take in a diet of like 100g protien, 100g carbohydrates, and 100g of fat (which is about what you need give or take 10g in any category). But you'll have to take in a lot more because you can't eaisily store them in a stable form in a pill.

Its not just that the macro-nutrients are there, they need to be in a form that your body can process and absorb.

>2000 kcal of fat plus extra for protien and carbs.
do you even /fit/?
that is a diet for fat-asses and/or bodybuilders.

They do a good job selling it anyway

180 tablets is 15 days. Weighs 1 lb.


A. With just Survival Tabs and water, depending on the circumstances of course, one could maintain oneself for 3-4 months without any major difficulties. When the Survival Tabs were first developed, there was a woman, deathly ill and expected to die soon, who could not keep anything down. Someone suggested the Survival Tabs. She went on them exclusively and lived 2 years.

Even in its most compact/concentrated form the sheer mass of fuel the body needs doesn't fit very well into pills.

Water would be an order of magnitude worse.

But that 100g takes water weight into account too.

If you dehydrated and powderized certain foods, im sure you could fit a serving or two into a couple pill capsules, right? Then all you do is drink a shitload of water or take a catalyst pill that would hydrate it in your tummy and make you instantly feel full. Imagine powderized beef jerky.

You could do it with a superfood like amaranth, quinoa, or kale which would supplement some protein, fibers, carbs, and even omega-3 fatty acids. Match it with a multivitamin and viola!

2 weeks of food for under $25?? Im solddd

Lol jk i would die from lack of junk food

>>Not having capsules to keep you fed and hydrated for weeks
How can you compress water into smaller water?

You still need X liters of water, whether in pill form, bottled form or cupped form.

>>208092
being hungry is good, the protein that manifests feelings of hunger keep you alive longer. And reducing your carbohydrate intake to 1/3 and increasing your protein intake will also extend your life (Its how we relativley tripled the lifespan of domestic animals, cats dogs etc. through diet alone)

>>208095
2000 kcal is roughly what the average person needs on a daily basis.

>>208070
The proteins and what not, yes. It is possible to put those into pill form. You will need to get your water elsewhere. Same with some form of calories and fat for long term. Also, anything you put in pill form will have to wind up there in a fashion that your body can digest, and for a lot of things that would be problematic.

Doing something like that long enough will cause you to be horrible at digesting anything. Your system needs a variety of different foods to keep being able to digest things. This is why people who don't eat meat can't digest it after a while.

While it is a nice thought, it is a bad idea for anything but emergency situations.

>>208182
Yeah, we would have to modify the digestive system heavily to digest compact pills effectivley. What I would look at instead is a possible pill form which can be easily dissolved or crushed up and added to water. This should help digestion 10fold, and you would be getting both your water and nutrient requirements at the same time.

capsules to keep you hydrated.
Already existing, they're called water bottles

this has got me curious, what food has the highest energy density?

>>208208
dried fruits, due to the sugar content per weight

>>208208
Suet, by far - pure fat at 9kCal/g. Pemmican's probably next - 50% rendered fat (9kCal/g), 50% dried fruit (4kCal/g), which makes 1kg of pemmican about 6500kCal, which would keep you in homeostasis for a couple days in all but the most extreme conditions.

Stick a glucose IV in your arm like they do coma patients, then, and take multivitamins. Enjoy your flatline of an existence.

>>208245
There's a reason why Pemmican's an ancient recipe that's still around; it worked REALLY well for the hunter-gatherer tribes across pre-colonized America.

>>208267

We weren't all hunter-gatherers. Pemmican, Wasni and all the other variants are excellent for travel and home eating.

Another more modern option for people who squick over rendered fat would be that peanut butter and vitamin mix the UN gives to starving kids. It's called Plumpy'Nut and you can make any of a number of variants on it. 1 lb of enhanced peanut butter and one of pemmican is a lot of fuel.

We're animals that happen to be slightly smarter than the rest of the animals on this planet. Our bodies require food and drink. Trying to circumvent that generally speaking leads to disease. Is this some sort of retarded transhumanism post?

Gentlemen, I have discovered real-life Lembas bread. A single bite can sustain a fully-grown man for a day.

More importantly, why the fuck do we still have no dehydrated water? It can't be that hard.

>>208411
Because dehydrate literally means "to remove water from"

I was thinking something similar. But if someone else wants to try an extreme diet, then post the terrible side effects for science...well, who am I to argue with that?

I wonder which deficiencies would lead to different diseases. I know that a diet of only corn leads to a deficiency in niacin. It's needed for the body to create seratonin for the nervous system. There is niacin in corn, but we have to soak the corn in lime in order to make it digestible.

Welcome to the reasons why doctors say something is good for you one day, then bad for you the next.

Another thing to remember is that most vitamins need to be taken with food in order to be digested properly. Allegedly, one way around this is to take a capsule of fish oil before the rest of the vitamins.

I'm in California. We had a large percentage of non-agrarians compared to the plains or up north.

Three Sisters agriculture and agroforestry had replaced that lifestyle almost 1000 years before Europeans arrived in the Northeast US where I'm from - walled towns, long houses and foot roads dotted the landscape. The People in Arizona and New Mexico where settled even longer.
