Yeah my roommate has commented on this as well. I'm thinking of adding in more nuts and other calorically dense foods. I've only been doing this for a few months so it's a bit of an experiment.

you probably just have a low natural appetite but most people need far, far more fat in order to feel satisfied and not crave food all day and binge on crap later.

nuts work great, but my personal favorite fat-booster is eggs, followed by lots of olive oil.

At rough estimate, like half the calories most people need: http://www.wolframalpha.com/input/?i=1+cup+oatmeal+%2B+1+tbs...

scaled to the 2000'calories in soylent: 2000/951*$6.20 = $13.04 or 43% more expensive than soylent's $9.11.

shopping and cooking and eating and cleaning for this must take at least around 1/2 hour - hour each day (compared to about 5 minutes for soylent) equals about 3-6% of your waking hours.

Also, for the first time in my adult life, I'm pretty well prepared for natural disaster. before I would only keep a couple days of food in my apt and a lot of that needed refrigeration or cooking. Now I have a couple of weeks worth at the ready.

I think, though that the value prop probably makes far more sense for single people without children. For them, preparing food is far less efficient and they have to coordinate their eating with others less often. Also, it probably makes less sense if your employer provides you with free meals.

Whey protein & milk and he would be fine I think.
