Vicc, thanks for the sensible advice. The idea that all the nutrients scale together is extremely appealing, and Rob seems to be making that claim in the packaging of original soylent when he says you can just eat more of it or less to suit your particular needs. But I wonder if the biology is really so tidy. Like, if I run an ultramarathon one day and the next day feel inclined to consume some three times my usual total fuel intake, does it really follow that it’s perfectly fine for me also to have three times the usual vitamin A? I mean, maybe it is, maybe extra exertions and stresses always draw on all nutritional inputs equally. But maybe not, maybe there are some core maintenance routines of the body that are unaffected by what I do or don’t do in terms of voluntary exercise. I wonder whether anybody knows the answer?
I am thinking of creating a DIY-complete recipe based on, say, 1200 calories, but then in practice handling the micronutrients separate from the macros. I would take my very carefully measured daily micronutrient mix and divide it into 3-4 roughly equal piles–at this point it’s not necessary to be exact, as long as I get all of them into me over the course of the day–then every time I want to eat I have a big heap of macros plus a little heap of micros, and if late in the day I run out of micros but still want to eat again I can mix up an extra meal of just macros…
In practice I don’t think it will be any more difficult than any other DIY. It will just require more and smaller containers.
What nutrients present the greatest danger of overdose? Is manganese a problem? I am very fond of oats. If I make oats my most important carbohydrate staple, and then there’s also manganese in my vitamin supplement (very likely), and manganese in the protein powder (also likely)… that could all add up to bump me over the limit.
@Tordenskjold, Well, at least bodyfat% has some kind of physiological reality, where weight is a complete chimera measuring nothing biologically real. People have just all collectively agreed to shut their eyes and hope that since it’s so easy and cheap to measure weight precisely and so difficult to measure bodyfat, that the two correlate reliably. But even bodyfat% strikes me as a fairly blunt instrument. Really, you think somebody with a tubby butt and thighs is the exact equivalent of somebody who has a lot of fat packed in around their internal organs, provided the two both have the same total fat percentage? Anyway, your fat’s going to collect where it collects; body composition is not in our direct control either.
