You need solid substances in your body to keep weight. You actually don't as easily digest vitamins and minerals from things such as tablets and health drinks as much as from actual solid food, so while you can probably stay alive with Soylent, chances are after a while you'd look like Death warmed over with the strength of a toothpick.

Do you have a source? Just interested.
Digestive organs require solid, hard food to keep them in working orderIt's why all these tube-feeders have terrible digestive tractsI heard it from my mommy (but she's probably right :L)
I don't even wanna bother reading that hippie-dippie nonsense.THE POINT IS: YOU NEED FOOD. ENOUGH SAID.
Oh look, it's igloos saying something silly again.You realize it's what's in something, not weather it's liquid or solid, that determines how your body can use it, right?
I realize that, but we need solids to survive, just drinking soy doodoo won't provide you with the energy and nutrients you need to survive.
