Just don't eat anything. For three days you should be fine. If your stomach hurts just drink water.

I'm pretty Sure you are a Woman going on a hike for multiple days and you don't want to poop in the wild? These problems sound quite familiar xD

Bro are you mailing yourself somewhere?

Just adding a comment so people will believe me when I tell them I was here when the "3 days without pooping" post happened :)

Good luck on your journey, OP!

This has to be a kink thing, one of the weirder ones. Holding a plug, not sweating, because it is not wished?

Else it is something illegal. Drug mule, crossing a border which would either make the drugs visible, or maybe another crime to not leave obvious DNA traces. No sweating to not look suspicious on control? Not much stuff to disguise the longer travel?

1 word: pancakes. Nature's cork.

Why do you need this?

A small bottle of olive oil. It's very high calorie so it will keep you somewhat energized in small quantities. Consumed in small amounts you may be able to go three days without shitting.

What I would do in this situation would be a 4-day fast. It's not for everybody, but you might want to at least consider it, because it's definitely doable, and some people even claim it's healthy (disclaimer: I am not a medical professional, don't take medical advice from random people on the internet).

To prepare, I would suggest switching to OMAD (one meal a day - effectively you will be fasting 23h every day) up until the trip. OMAD will help your body adjust to long periods of not eating. To be successful with OMAD, you need to ensure that your single meal will cover your daily calorie and nutrient needs. There's a bunch of resources about it online if you search.

Eat your last meal 48h before the trip - this will give you a chance to empty your bowels before you leave. Every day, make sure you drink enough electrolytes + take multivitamins. On the final day of your trip, it should be safe to have a SMALL meal (do not overdo it, you can hurt yourself by eating too much after a fast) - it should take your body over a full day before you'll need to poop.

How long do you have to prepare? Personally, when I first started doing OMAD, it took me over a month before my body became adjusted to fasting. But now, it just feels completely natural.

I once survived 3 days without pooping at a festival. The secret was 15 liters of beer and ~ 9 cans of ravioli. But I peed A LOT.

I wonder if doing a colon cleanse beforehand help? Similar to what people do before a colonoscopy.

Also, it is an odd request but I’m now fully vested in your post to see what others suggest.

Cheese.

Would love an update haha

I just want to say that this post is awesome. Also Military MREs, come in a convenient form factor and had the effect of keeping me well fed and also completely blocked up during whole field exercises.

I'm so happy I can be a part of this historical moment.

I think David Blane talked about this on Hot Ones

I need to survive for 3 days without pooping, and eating as little as possible. I can pee, but not very often. It can’t take up too much space. What food do I pack?

Please stop asking because I am not telling anyone the reason.

I mean, working overtime in Amazon is no shame
