It is possible to slow down the breakdown by removing enzymes (or just striping the human body of parts of organs) and hence it would be possible to do this.

Back to the question.
It has not been confirmed that it is impossible as we can find all nutrients and Amino acids, therefore we can extract all nutrients and Amino acids we need, it wouldn't be cost effective, but on the other hand this is a theoretical question.

Second source just lists what we mainly need to survive...

I think you wont be able to survive on just nutrients alone and you would need some form of solid for your body to break down or else your stomach acid would start eating your stomach lining because of an excess of enzymes

Please provide a source to back up your claim that an excess of enzymes would cause the stomach to break down.

Ok lets see... It's possible but it would take several years to poeple to accustom to change thier alimentary habits.

If your diet is bassed only on meal, candies, industrializated food w/e, And you prettend to change it to a healthy diet. your organism can suffer agitated alimentary changes, and that can cause injuries.

I recommend alot Water. and exercise.
