For instance: you can stop by http://www.truenutrition.com/ or scores of other custom and premixed Meal Replacement Powder websites and get something cheaper and customized to your own activities and lifestyle.
Hospitals regularly feed people pre-mixed meal replacements when chewing food is not an option.
Soylent is just another old MRP with stupid "geek" marketing. Which should come as no surprise as the rest of the athletic supplement and MRP market is also just basic macronutrients and hokum with "bro" marketing. I can't wait for Soylent Monster Xtreme with Branched Chain Amino Acids. There's nothing wrong with it. Its probably no more over-priced than GNC. The only new things about it is its press on tech sites.
Which you think might know better, but the tech world is so narrow minded that obvious cons like this one can turn into a viable business.
