Why cant you survive only on raw leafy vegetables?

Answer 1

It may be possible if done gradually, very slowly over the course of many years. Most people would die trying this but knowing the will power of survival especially in humans I'd say some people would make it.

Your stomach and intestines would need to adapt by slowing down your metabolism greatly so the leafy substance in your body would produce a great amount of bacteria, your body then would have to absorb a large amount of bacteria as a source of energy.

Answer 2

Humans need nutrients like carbohydrates,fats,proteins,vitamins and minerals.Raw leafy vegetables contain only vitamins and minerals.Therefore we cannot get the other nutrients if we only eat raw leafy vegetables

Answer 3

A vegetable (fruit) is alive, living, and growing. It contains (most) of the sugars, lipids, proteins [forget about amino acids because all proteins are made of amino acids], and every cell contains DNA and Rna which are comprised of all types of nucleic acids. What more could be asked for ?

This diet would really need a protein and a multivitamin (just to cover the missed spots) adjunct.

Lipids may be tough to replenish with only vegetables, so corn oil, or any other seed or nut oil could be used, margarine or mayonnaise and/or peanut butter

Eggs, milk, cheese, nuts and especially do-nuts are usually fine.

Garnish with whole grains.
