That to me doesn't sound like a recommendation to actually replace every single meal for that month. Rather, it's a unit of measurement that provides better context than simply giving the number of kilograms of powder you'll be receiving. Even so, I don't think it would be harmful to do it for an entire month anyways, and I doubt very many people will be that hardcore about it. It will work perfectly as an occasional meal replacement for busy geeks on the go. Attacking the extreme case is attacking the straw man, IMO.

Perhaps. There seems to be a lot of people who seem to have thought what I thought, though. Maybe it would be better if they gave an all-out disclaimer saying that, "no, Soylent cannot be considered as a replacement for your balanced diet"?

From his blog, he really did seem to push the idea of making Soylent his only food -- IIRC he felt like that the traditional idea of eating from a lot of different sources was stressful (I guess the decision of what to eat, etc, was stressful). His blog seems to be down for me right now, though, so I can't confirm that.

Yeah, I agree they should state that. He did mention a few times that he eats normal meals when he wants to, but even at that it was only a few times a week. If I buy the stuff I'm likely to only replace my breakfasts and lunches and continue having dinner with my family.
