But he says that he didn't only consume Soylent for a week, that he still ate regular meals. And then went on to say that there were times when he drank Soylent he would have preferred a regular meal. It makes no sense, why not just drink Soylent when the lack of taste was less important than the efficiency? This would have been a fairer test. If by the end of the week the guy was no longer drinking Soylent for any meals, then I'd buy that Soylent was doomed, but that's not what the experiment was.
