Well, okay. Just because vegetarians do/did it, doesn’t automatically make it good, much less optimum (take a look at soy, for instance). That being said, the question was about the effects of not sticking to consuming soylent in larger amounts at a time, and I was simply adding to the discussion. For clarity’s sake I will edit the post, but I will also add here that it isn’t that you don’t absorb any of the protein, it’s simply that your body can’t absorb and utilize all of it if there isn’t a large enough intake at one point in time.
This doesn’t necessarily mean it’s awful to consume sporadically, but it is an important point to consider. Ultimately, your choices on how you consume will affect your heath one way or another, and it’s up to you (and your doctor/nutritionist/whatever) to decide what you should do, I’m just trying to help paint a fuller picture of what happens overall.
