TL;DR Someone trying to sell you on another crazy diet.

A complete enteral diet (when you're in the hospital and they feed it to you in a tube) is both extremely hard to achieve and expensive, not to mention the collateral effects. Then there's this guy claiming that he can not only live on a carb/protein/fat shake he made on his kitchen, but that it gave him superpowers and it's cheap to boot. He even gave it a market name already.

Not flying with me.

I agree that this is most likely a scam, but just wanted to point out that the 'market name' is just a reference to a movie called 'Soylent Green': http://en.wikipedia.org/wiki/Soylent_Green

I think you are mistaking parenteral and enteral. The difference is where the tube goes. Feeding someone with a tube is difficult only if the tube goes into the bloodstream.

If it goes to the stomach, a normal meal + a blender is all that is needed (or the fancy and overpriced equivalents sold for a small fortune to the hospitals)

If it goes to the bloodstream, it can't be food, and the problem is we don't exactly know yet everything it should contain.

For example, I remember in ICUs in the 1990s and early 2000, carnithin was the topic of many discussions. See for example http://www.ncbi.nlm.nih.gov/pubmed/2115077

There must be a new fad now.
