Sigh. If you are drinking a Soylent or some other drink because you literally don't have the time to get up from your desk for 30-60 minutes for a meal I question what type of human existence you are living. There are so many things central to living life that revolve around eating (social benefits, maybe fresh air and sunshine, tasting and smelling the food itself) that one misses out on by just drinking a shake and not seeing daylight for days on end. It seems like another way to make people more productive. Who needs a lunch break? Just drink a shake and keep coding! If you don't have any ownership in what you are making why one would give up one of the rights they have as a worker, a break in the day to get something to eat, is beyond me.
With that said I understand the value of a meal replacement if you are trying to loose weight. Soylent seems to be better vs the older meal replacement shakes out there, ie that slim fast junk.
