    Followed this a little bit. Soylent is interesting, but could never be an actual extended replacement for food.

    Why? Muscles in the human stomach move food around using Peristalsis. When 100% of your calories are in a liquid form, the muscles have nothing to act on. There's also the fact that, since you're guzzling a bunch of liquids, expect explosive diarrhea to go along with your hunger pangs and constantly rumbling tummy.

    Might be fine to do for a test drive, but biologically, humans aren't really setup to handle constant liquid diets. I did a two-week liquid diet with the wife when she was going in for stomach surgery and it's fucking miserable.

      Very interesting observation. Any idea on how long it would take for those muscles to weaken to the point where they are too weak to digest real food?

      But some experts say that you should chew your food until it is liquid before you swallow it. So the stomach should have no problem with liquid food. I'm curious about the liquid diet that you were on, and why it was so awful.

      I know from making my own protein smoothies, that if you include enough protein, fiber and fat in the smoothie, it can actually keep you feeling full for a while. If done right, a balanced liquid food would be just the same as a balanced solid diet, but the work that your teeth would do in turning it into liquid has already been done for you.

      Although it does raise the question of what would happen to us in evolutionary terms if we all had liquid diets. Would be evolve into beings that were unable to chew food properly?

      Did you include protein and fat as part of the liquid meals?
