If poo is the waste product of what we eat after our body has extracted the nutrients we need, what would we need to eat to produce none?

Something that provided exactly the right amount of nutrients our body needs without anything left over.

That's pretty impossible to do because everyone has different nutritional requirements according to their lifestyle. Even if you analysed someone's body you wouldn't be able to predict how active they are going to be so you could probably never make a 'no waste' diet.

In biology we were discussing the 'perfect protein' theory, which would be a kind of protien that provides exactly the right amount of amino acids for us to use, but such a protein doesn't exist and again, it would be different for every individual.

You could investigate human breast milk. Pooing anything between several times a day and once a week is quite normal for a breastfed infant. Breast milk is about as perfectly geared to the needs of human infants as it gets. It can be replaced by formula, and babies will thrive, but there are plenty of studies around showing that when all circumstances are as controlled for as possible, outcomes are better for breastfed babies.

Ah yes, and of course "baby's first stool" was discussed on the show last week I believe. If a baby needs to poo even after placental nutrition then poo must be quite inevitable. I only wondered because of those "recommended daily amounts" on vitamin supplements , if it would be possible.

There was a posting some time ago involving vanilla ice-cream and porn movies, but I don't think I want to go there.

Actually (and I'm as much an expert in this field as I am in synchro-cyclotron technology) a lot of stuff that goes through you must be what used to be called "roughage" and has to be eaten for your insides to work properly.

Army field rations (particularly the individual packs) are deliberatly very low in roughage, this is to reduce the amount of time that a soldier in a battlezone needs to spend wandering amongst the bushes with a shovel. In theory the ration packs should reduce the frequency of hole digging to once every 3 days, the big drawback is that since everyone in a battalion starts eating the rations at the same time, when the 3rd day dawns it is the 3rd day for everybody.
