It's not much to look at, but Rob Rheinhart insists that Soylent -- a liquid food replacement he's been using for several months -- could be the future of food.

Guest host Kevin Sylvester talks to the 25-year-old inventor about how he thinks his liquid meals can change the world -- addressing everything from food insecurity to obesity --  why he distinguishes between recreational eating and body fuel, and what he says to critics and skeptics.

Rheinhart admits that the "mildly sweet" drink with a milkshake-like texture may seem weird to some, but argues that new sources of nutrition often take a while to hit the mainstream.

"Think about the first person to drink the milk of a cow," he said.
